Background technique

With the launch of the new standard protocol of the seventh generation Wi-Fi wireless network (Wi-Fi 7), Multi-link Operation (MLO) technology has been introduced, allowing electronic devices such as mobile phones, virtual reality devices and routers to be used Multiple links send data simultaneously. The advantage of MLO technology is that by using multiple links to send data at the same time, latency can be reduced and bandwidth efficiency improved. However, the current MLO standard does not specify how to distribute data packets sent by the upper layer to each link when there are multiple available links. If the data packet allocation is not properly allocated according to the capabilities of each underlying link (such as competition conditions and interference conditions), it may result in that the link capabilities of better quality are wasted in a random interference environment, while the capabilities of links with poorer quality are wasted. The path is overloaded, which leads to an unexpected increase in transmission delay, which is even worse than the delay in a single link without MLO. In addition, due to the need to open multiple links at the same time, the power consumption of MLO technology increases multiple times compared with a single link without MLO.

With the launch of the new standard protocol of the seventh generation Wi-Fi wireless network (Wi-Fi 7), Multi-link Operation (MLO) technology has been introduced, allowing electronic devices such as mobile phones, virtual reality devices and routers to be used Multiple links send data simultaneously. The advantage of MLO technology is that because the probability of simultaneous contention and interference on multiple links is lower, MLO technology can reduce the time required to send data by using multiple links at the same time compared to the previous single-link transmission method. delay and improve bandwidth efficiency. Among them, the competition situation refers to the situation where a long backoff waiting time is required, and the interference situation refers to the situation where the transmission failure rate is high and retransmission is required.

However, the current MLO standard does not specify how to distribute data packets sent by the upper layer (above the network layer of OSI layer seven) to the Wi-Fi bottom layer of 802.11 (wireless local area network standard) when there are multiple available links. (MAC/PHY layer) on each link. If the data packet allocation is not properly allocated according to the capabilities of each underlying link (such as competition conditions and interference conditions), it may result in that the link capabilities of better quality are wasted in a random interference environment, while the capabilities of links with poorer quality are wasted. The path is overloaded, which leads to an unexpected increase in transmission delay, which is even worse than the delay in a single link without MLO. In addition, due to the need to open multiple links at the same time, the power consumption of MLO technology increases multiple times compared with a single link without MLO.

Among them, the OSI (Open System Interconnect) model is called the Open Communication System Interconnect Reference Model. It is a standard framework proposed by the International Organization for Standardization (ISO) that attempts to interconnect various computers into networks around the world. OSI divides the computer network architecture into seven layers. Each layer implements its own functions and protocols and completes interface communication with adjacent layers. That is, each layer plays a fixed role and does not interfere with each other. Among them, the seven-layer structure includes physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. The Physical Layer defines the physical structure of the network, the electromagnetic standard of transmission, the encoding of bit streams and the time principles of the network, such as time division multiplexing and frequency division multiplexing; the physical layer determines the type of network connection ( end-to-end or multi-end connections) and physical topology. The data link layer (DataLink eview) is used to establish a data link connection on two hosts, transmit data signals to the physical layer, and process the signals to ensure error-free and reasonable transmission. The Network Layer is mainly responsible for routing, selecting appropriate paths, and performing blocking control and other functions. The Transfer Layer is the most critical layer, providing users with reliable end-to-end services. It shields the details of lower-layer data communication, so that users and applications do not need to consider actual communication. method. The Session Layer is mainly responsible for communication between two session processes, that is, information exchange between two session layer entities and management of data exchange. The Presentation Layer is used to process the representation method of communication signals, translate between different formats, and is responsible for data encryption and decryption, data compression and recovery. The Application Layer is used to maintain data records required to establish connections between applications to serve users.

MAC (Medium Access Control), referred to as media access control. The MAC layer belongs to the data link layer in the OSI model, and its main task is to determine who to send the data packet to. The data link layer includes the MAC (Media Access Control) sublayer and LLC (Logical Link Control) sublayer.

PHY (physical), referred to as physical layer, is an abbreviation for the physical layer of the OSI model.

The embodiment of this application proposes a data packet distribution method to enhance the technical details that are not taken into account by the current Wi-Fi 7 new standard protocol. During the process of the Wi-Fi device sending the data packet, the data packet allocation method is dynamically and real-time based on the available multiple data packets. Link competition and interference conditions effectively and optimally allocate the data transmission load (i.e. packet sending ratio) of multiple links. Compared with the original mechanism, it can reduce delay, increase bandwidth and reduce power consumption. Effect.

Please refer to Figures 2 to 3. Figure 2 is a schematic flowchart of a data packet allocation method provided by an embodiment of the present application, and Figure 3 is a schematic diagram of an application scenario of the data packet allocation method provided by an embodiment of the present application. This method can be applied to the first electronic device 10 as shown in Figure 1. For example, the first electronic device 10 can be a radio access network device or a terminal device. The method includes:

Step 110: When there are multiple links for communication and interaction between the first electronic device and the second electronic device, and a data packet sending request is received, obtain the data packet status information and each of the multiple links. Communication status information of the link.

For example, the link may be a 2.4 gigahertz (GHz) link, a 4GHz link, a 5GHz link, a 6GHz link, etc.

For example, the first electronic device may use the MLO mechanism of Wi-Fi 7, and multiple links for communication interaction may be established between the first electronic device and the second electronic device. Each time the first electronic device (such as the MLO device) receives a notification from the upper layer and is ready to send a data packet, it will send a request based on the received data packet to obtain the data packet status information and the communication status of each link in the multiple links. information. In subsequent steps, the data packet status information and the communication status information of each link in the multiple links are used as input, and a set of decision-making mechanisms are used to make real-time decisions on the status of the data packets currently to be sent on multiple available links. The goal is to reach the minimum total sending delay and successfully send all data packets in the packet sending queue. The decision-making mechanism for the proportion of contract issuance can make real-time decisions before each contract issuance without switching to MLO mode.

The data packet status information may include at least one of the service type of each data packet in the packet sending queue and the length of the data packets (MPDU) currently stacked in the packet sending queue.

For example, in communication networks, the transmission and processing of data packets are very critical parts. In order to better manage and optimize the network, it is necessary to understand the status information of data packets. This information may include the status of packets in the send queue and the length of packets accumulated in the send queue.

Specifically, each data packet in the packet sending queue usually contains its business type information. This is because in the network, different business types may require different processing methods. For example, some traffic types may be more sensitive to latency, while other traffic types may be more sensitive to packet loss. Therefore, by understanding the service type of each data packet, we can better adjust the packet proportion decision for each link to meet different needs.

In addition, it is also necessary to understand the length of data packets currently accumulated in the packet sending queue to determine network congestion. If the length of data packets currently accumulated in the packet sending queue suddenly increases, this may mean that the network is experiencing congestion. At this time, the packet sending ratio decision of each link may need to be adjusted to avoid network overload.

Among them, the communication status information may include the service type of each link, the real-time transmission rate of each link, the packet sending success rate of each link, the backoff waiting time of each link, and the packet loss rate of each link. , at least one of the bandwidth utilization of each link, the signal strength of each link, the receiving sensitivity of each link, and the delay of each link.

For example, in communication networks, the communication status information of each link plays a key role in the transmission selection and optimization of data packets. The following is a detailed description of the communication status information such as service type, real-time transmission rate, packet sending success rate, backoff waiting time, packet loss rate, bandwidth utilization, signal strength, receiving sensitivity and delay of each link.

For example, the service type of each link: Each link may carry different service types, such as video streams, audio streams, data packets, etc. Depending on the type of business, the link to transmit the data packets can be selected more precisely to ensure the best data transmission quality. For example, for high real-time business types, links with low latency and high reliability should be selected. You can learn the link usage through the service type of each link. For example, if a link mainly carries real-time audio and video traffic, it may need to be allocated more bandwidth and priority to ensure stable operation.

For example, the real-time transmission rate of each link: The real-time transmission rate reflects the bandwidth of the link and is a key factor in determining whether a data packet can be successfully transmitted within a given time. By monitoring the real-time transmission rate, a link with sufficient bandwidth can be selected to transmit data packets to ensure the stability and reliability of data transmission. The maximum transmission capacity of each link can be understood through its real-time transmission rate. If the real-time transmission rate of a link suddenly drops, it may mean that the link is faulty or about to be overloaded. At this time, close attention is required and corresponding adjustments may be required.

For example, the packet sending success rate of each link: The packet sending success rate refers to the rate of a link successfully sending data packets. A high packet transmission success rate means that the communication quality of the link is high and the possibility of data packet loss is small. When selecting a link to transmit data packets, consider using a link with a high packet transmission success rate. The data packet transmission status of each link can be understood through the packet sending success rate of each link. If the packet sending success rate of a link continues to be low, it may mean that the link has a packet loss problem or other faults. That is, the lower the packet sending success rate, the higher the interference level in the link. In this case, troubleshooting and repair.

For example, the backoff waiting time of each link: When the communication quality of a link decreases, a backoff waiting time strategy is usually adopted to avoid data packet collision and loss. The shorter the backoff waiting time means that the link may be less congested, and priority can be given to using such a link to transmit data packets. Link congestion can be understood through the backoff waiting time of each link. If the backoff waiting time of a link suddenly increases, it may mean that the link is experiencing congestion. That is, the longer the backoff waiting time may be, the stronger the competition in the link will be. At this time, the packet sending ratio decision of each link needs to be adjusted to Avoid overloading this link.

For example, packet loss rate per link: Packet loss rate refers to the rate at which packets are lost on a link. High packet loss rates can lead to incomplete and delayed data transmission, so choosing a link with a low packet loss rate can ensure better communication quality.

For example, bandwidth utilization per link: Bandwidth utilization is the ratio of the actual bandwidth used by a link to its maximum available bandwidth. High bandwidth utilization may mean higher congestion on the link, so when choosing a link to transmit packets, you can choose a link with low bandwidth utilization to ensure smoother data transmission.

For example, signal strength per link: Signal strength reflects the reception quality of a wireless communications link and is typically measured in decibels (dB). When selecting a wireless communication link, you can choose a link with strong signal strength to ensure the stability and reliability of data transmission.

For example, the receive sensitivity of each link: Receive sensitivity refers to the ability of a link to successfully receive weak signals. High receiving sensitivity means that the link can work properly over long distances or in poor signal environments. When selecting a link to transmit packets, consider using a link with high receive sensitivity.

For example, latency per link: Latency refers to the time it takes for a data packet to travel from the sender to the receiver. When selecting a link to transmit data packets, you can choose a link with low latency to ensure that real-time services can be transmitted and processed in a timely manner.

Among them, according to different business requirements and communication environments, you can consider using one or more of the above-mentioned data packet status information and communication status information to optimize the transmission path of the data packet to ensure the best communication quality and user experience.

Step 120: Based on at least one of the data packet status information and the communication status information of each link in the multiple links, determine whether the data packet in the packet sending queue is in at least part of the multiple links. The proportion of packets sent corresponding to each link in the road.

In some embodiments, before determining the proportion of data packets in the packet sending queue corresponding to each link in at least part of the multiple links, the method further includes:

At least some links for transmitting data packets are selected from the plurality of links according to at least one of the data packet status information and the communication status information of each link in the plurality of links.

In some embodiments, the data packet status information includes the service type of each data packet in the packet sending queue, and the communication status information includes the service type of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , including: selecting a link whose service type matches the service type of the data packet to be sent from the plurality of links according to the service type of each data packet in the packet sending queue and the service type of each link. Road serves as at least part of the link used to transmit data packets.

For example, assume there is a data packet sending queue that contains multiple service types, including video streams, audio streams, and ordinary data packets. At the same time, there are multiple available links, each of which carries different types of services. For example, link A mainly carries video streaming services, link B mainly carries audio streaming services, and link C mainly carries ordinary data packet services. Link D carries other data services. For example, other data business types may also include network data transmission business, file transfer business, email business, video conferencing business, online game business, remote login business, online payment business, Internet of Things business, e-commerce business and location service business, etc. Any kind of business.

When selecting a link for transmitting data packets, the service type of each data packet in the data packet queue can be matched with the service type of each link. For example, for data packets of the video streaming service type, link A can be selected for transmission; for data packets of the audio streaming service type, link B can be selected for transmission; for data packets of the ordinary data packet type, link C can be selected Make the transfer. For example, at least some of the links selected for transmitting data packets according to the service type include link A, link B and link C. This business type matching method can ensure that data packets can receive the best processing and transmission effects during transmission. For example, video stream data packets can achieve higher transmission rates and lower packet loss rates when transmitted on link A, because link A mainly carries video streaming services and has better video streaming transmission performance. Similarly, audio stream data packets can be transmitted on link B to achieve lower latency and higher audio quality, because link B mainly carries audio stream services and has better audio stream transmission performance. Through this service type matching method, the link for transmitting data packets can be selected more accurately, thereby improving the reliability and quality of data transmission. Of course, in practical applications, other factors need to be considered, such as the real-time transmission rate of the link, packet transmission success rate, backoff waiting time, packet loss rate, bandwidth utilization, signal strength, receiving sensitivity and delay, etc., after comprehensive weighing Select the best or better link for data transmission.

In some embodiments, the communication status information includes a real-time transmission rate of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , including: according to the real-time transmission rate of each link, selecting a link with a real-time transmission rate greater than a rate threshold from the plurality of links as at least part of the link used to transmit the data packet.

For example, assume there are 5 communication links, and their real-time transmission rates are 5Mbps, 10Mbps, 50Mbps, 80Mbps and 100Mbps respectively. Now you need to select the link to transmit the data packet based on the real-time transmission rate of each link. Assume that the rate threshold is set to 20Mbps. According to this rate threshold, links with real-time transmission rates of 5Mbps and 10Mbps will not be selected as links to transmit data packets because their rates are lower than the rate threshold. Links with real-time transmission rates of 50Mbps, 80Mbps, and 100Mbps have rates higher than the rate threshold of 20Mbps, so they can all be selected as links for transmitting data packets. The rate threshold in this example is just an example value. In actual applications, the rate threshold setting will be determined based on specific application requirements and network conditions. For example, for data transmission with high real-time requirements, a link with a higher real-time transmission rate may be selected; while for transmission with a large amount of data, a link with a larger bandwidth may be selected. In addition, when selecting a link for transmitting data packets, in addition to the real-time transmission rate, other factors need to be considered, such as the link's business type, packet sending success rate, backoff waiting time, packet loss rate, bandwidth utilization, Signal strength, receiving sensitivity and delay, etc., are comprehensively weighed to select the optimal or superior link for data transmission.

In some embodiments, the communication status information includes the packet sending success rate of each link or the backoff waiting time of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , including: selecting a preset number of links from the multiple links as links for transmitting data in order from high to low according to the packet sending success rate of each link in the multiple links. At least part of the links of the packet; or select a preset number of links from the plurality of links in order of the backoff waiting time of each link in the plurality of links from short to long. As at least part of the link used to transmit data packets.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The packet sending success rate of each link reflects the data transmission reliability of the link. First, the packet sending success rate of each link needs to be counted in real time. This can be achieved by recording the number of successful and failed packet transmissions on each link during data transmission. By calculating the ratio of successful transmissions to the total number of transmissions, the packet sending success rate of each link can be obtained. Then, the links are sorted according to the packet sending success rate of each link, and links with a preset number of links are selected from high to low. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the real-time transmission rate of the link, service type, backoff waiting time, packet loss rate, bandwidth utilization, signal strength, receiving sensitivity and delay, etc., and the best or better solution can be selected after comprehensive weighing. link for data transmission.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The backoff waiting time of each link reflects the data transmission efficiency of the link. First, the backoff waiting time of each link needs to be counted in real time. This can be achieved by recording packet transmission delays on each link during data transmission. By calculating the ratio of the transmission delay of each packet to the total number of transmitted packets, the backoff waiting time of each link can be obtained. Then, sort according to the backoff waiting time of each link, and select the link with the preset number of links from short to long. This avoids excessive packet accumulation on certain links, thereby optimizing the performance of the entire data transmission network. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the link's packet sending success rate, real-time transmission rate, service type, packet loss rate, bandwidth utilization, signal strength, receiving sensitivity and delay, etc., and the best or better solution can be selected after comprehensive weighing. link for data transmission.

In some embodiments, the communication status information may also include the packet loss rate of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , may also include: according to the packet loss rate of each link, selecting a link with a packet loss rate lower than a preset packet loss threshold from the plurality of links as at least part of the link used to transmit the data packet .

For example, there is a data transmission network composed of 5 links, which connect different source nodes and destination nodes respectively. The packet loss rate of each link reflects the data transmission reliability of the link. First, the packet loss rate of each link needs to be counted in real time. This can be achieved by recording the number of packet losses on each link during data transmission. By calculating the ratio of the number of lost packets to the total number of transmitted packets, the packet loss rate of each link can be obtained. Then, sort according to the packet loss rate of each link, and select links below the preset packet loss threshold from low to high. In this example, the preset packet loss threshold is 5%, that is, only links with a packet loss rate lower than 5% are selected as at least part of the links used to transmit data packets. By counting the packet loss rate of each link in real time and comparing it with the preset packet loss threshold, it is possible to determine which links have a packet loss rate lower than the preset threshold, thereby selecting these reliable links for data transmission. . This ensures the stability and reliability of data transmission and reduces errors and retransmissions caused by packet loss. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the link's packet sending success rate, real-time transmission rate, service type, backoff waiting time, bandwidth utilization, signal strength, receiving sensitivity and delay, etc., and the best or better one should be selected after comprehensive weighing. link for data transmission.

In some embodiments, the communication status information may also include bandwidth utilization of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , can also include:

According to the bandwidth utilization of each link, a link with a bandwidth utilization lower than a preset bandwidth threshold is selected from the plurality of links as at least part of the link used to transmit the data packet.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The bandwidth utilization of each link reflects the data transmission capability of the link. First, real-time statistics on the bandwidth utilization of each link are required. This can be achieved by recording the data traffic on each link during data transmission. By calculating the ratio of data traffic to link bandwidth, the bandwidth utilization of each link can be obtained. Then, each link is sorted according to its bandwidth utilization, and links below the preset bandwidth threshold are selected from low to high. In this example, the preset bandwidth threshold is 80%, that is, only links with bandwidth utilization lower than 80% are selected as at least part of the links used to transmit data packets. By counting the bandwidth utilization of each link in real time and comparing it with the preset bandwidth threshold, it is possible to determine which links have bandwidth utilization lower than the preset threshold, thereby selecting these underutilized links for use. data transmission. This can ensure the stability and reliability of data transmission while optimizing link utilization and reducing bandwidth waste. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the packet sending success rate of the link, real-time transmission rate, service type, backoff waiting time, signal strength, receiving sensitivity, delay, packet loss rate, etc., and the optimal or better one should be selected after comprehensive weighing. link for data transmission.

In some embodiments, the communication status information may also include the signal strength of each link;

and selecting at least part of the links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , may also include: selecting a link whose signal strength is greater than a preset signal threshold from the plurality of links as at least part of the link used to transmit the data packet according to the signal strength of each link.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The signal strength of each link reflects the quality of data transmission on that link. First, the signal strength of each link needs to be counted in real time. This can be achieved by recording signal strength values on each link during data transmission. Usually, the signal strength value can be expressed in decibels (dB) or other corresponding units. Then, each link is sorted according to its signal strength, and links above the preset signal threshold are selected from high to low. In this example, the preset signal threshold is -60dBm (decibel milliwatts), that is, only links with signal strengths higher than -60dBm are selected as at least part of the links used to transmit data packets. By counting the signal strength of each link in real time and comparing it with the preset signal threshold, it is possible to determine which links have a signal strength higher than the preset signal threshold, thereby selecting these links with stronger signal strength for data transmission. This ensures the stability and reliability of data transmission and reduces transmission errors and retransmissions caused by insufficient signal strength. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the link's packet sending success rate, real-time transmission rate, service type, backoff waiting time, bandwidth utilization, reception sensitivity, delay, packet loss rate, etc., and the optimal or better option can be selected after comprehensive weighing. link for data transmission.

In some embodiments, the communication status information may also include the reception sensitivity of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , may also include: selecting a link with a reception sensitivity higher than a preset reception sensitivity threshold from the plurality of links as at least part of the link used to transmit the data packet according to the reception sensitivity of each link.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The receive sensitivity of each link reflects the data reception capability of that link. First, real-time statistics on the receiving sensitivity of each link are required. This can be achieved by recording the minimum receivable signal strength on each link during data transmission. Minimum Receiveable Signal Strength is usually a numerical value that represents the lowest signal strength of a link when a packet is received. Then, each link is sorted according to its reception sensitivity, and links above the preset reception sensitivity threshold are selected from high to low. In this example, the preset reception sensitivity threshold is -90dBm (decibel milliwatt), that is, only links with reception sensitivity higher than -90dBm are selected as at least part of the links used to transmit data packets. By counting the reception sensitivity of each link in real time and comparing it with the preset reception sensitivity threshold, it is possible to determine which links have a reception sensitivity higher than the preset threshold, thereby selecting these links that are more sensitive to signals for data use. transmission. This can ensure the stability and reliability of data transmission while optimizing the reception capability of data packets and reducing the bit error rate. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the link's packet delivery success rate, real-time transmission rate, service type, backoff waiting time, bandwidth utilization, signal strength, delay, packet loss rate, etc., and then choose the best or better option after comprehensive weighing. link for data transmission.

In some embodiments, the communication status information may also include the delay of each link;

Selecting at least some links from the plurality of links for transmitting the data packet based on at least one of the data packet status information and the communication status information of each link in the plurality of links. , may also include: selecting a link with a delay less than a preset delay threshold from the plurality of links as at least part of the link used to transmit the data packet according to the delay of each link.

For example, assume there is a data transmission network consisting of 5 links that connect different source nodes and destination nodes respectively. The latency of each link reflects the data transmission speed of that link. First, the delay of each link needs to be measured in real time. This can be achieved by recording packet transmission delays on each link during data transmission. By calculating the transmission time of a data packet from the source node to the destination node, the delay of each link can be obtained. Then, each link is sorted according to the delay, and links below the preset delay threshold are selected from low to high. In this example, the preset delay threshold is 100 ms (milliseconds), that is, only links with a delay less than 100 ms are selected as at least part of the links used to transmit data packets. By counting the delay of each link in real time and comparing it with the preset delay threshold, it is possible to determine which links have a delay less than the preset threshold, thereby selecting these links with faster transmission speeds for data transmission. . This can ensure the stability and reliability of data transmission while optimizing the transmission speed of data packets and reducing the impact of transmission delay on the performance of the entire network. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered, such as the link's packet sending success rate, real-time transmission rate, service type, backoff waiting time, bandwidth utilization, signal strength, packet loss rate and reception sensitivity, etc., and then choose the best or better option after comprehensive weighing. link for data transmission.

For example, the source node may be the first electronic device 10, and the target node may be the second electronic device 20 connected to each link.

In some embodiments, the communication status information includes the packet sending success rate of each link;

Determining, based on at least one of the data packet status information and the communication status information of each link in the plurality of links, that the data packet in the packet sending queue is in at least part of the plurality of links. The proportion of packets sent corresponding to each link in , including:

Based on the packet sending success rate of each link, according to the order of the packet sending success rate of each link in at least some of the links from high to low, the packet sending proportion is allocated from large to small, where, The link with the highest packet sending success rate among the multiple links is assigned the largest packet sending ratio.

For example, three links are pre-selected as at least part of the links used to transmit data packets. Next, one needs to predict the performance of these selected links over a future period of time. Since environmental interference factors usually persist for a certain period of time (for example, the time window is 5-10 minutes), changes in the packet sending success rate within this time window can be used to predict link performance in the future. For example, if the packet sending success rate of a link has remained above 90% in the last 5 minutes, it can be predicted that the performance of this link will be relatively stable in the future. Then, the proportion of data packets sent is allocated based on the predicted link performance. Since the higher the packet sending success rate, it means that a certain number of data packets require fewer retransmissions, so it can be speculated that the link can complete data transmission faster. Therefore, try to allocate as many data packets to the link as possible. In this way, links with high packet transmission success rates can be used to improve the performance of the entire data transmission network. Wherein, sorting is performed according to the packet sending success rate of each link in at least some of the links selected for transmitting data packets, and at least some of the links are selected from high to low. In this example, the link with the highest packet sending success rate is selected as the link with the highest priority, and then other links are selected in order of packet sending success rate. In this example, the total packet delivery ratio is divided into three parts, and the corresponding packet delivery ratio is allocated according to the packet delivery success rate of each link. For example, if the packet sending success rate of the first link is 90%, the packet sending proportion allocated to this link is 50%; if the packet sending success rate of the second link is 80%, the packet sending success rate allocated to this link The packet sending ratio of is 30%, and by analogy, if the packet sending success rate of the second link is 70%, the packet sending ratio allocated to this link is 20%. In this way, it can be ensured that during data transmission, links with higher packet sending success rates will send more data packets, thereby optimizing the performance of the entire data transmission network. At the same time, allocating the largest packet sending ratio to the link with the highest packet sending success rate among multiple links can further enhance the data transmission performance of the link. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered and the optimal link for data transmission needs to be selected after comprehensive weighing.

In some embodiments, the data packet status information includes the length of data packets currently accumulated in the packet sending queue;

Determining, based on at least one of the data packet status information and the communication status information of each link in the plurality of links, that the data packet in the packet sending queue is in at least part of the plurality of links. The packet sending proportion corresponding to each link in the packet sending queue also includes: based on the length of the data packets currently accumulated in the packet sending queue and the packet sending success rate of each link, when the data currently accumulated in the packet sending queue When the packet length is less than the data length threshold, and the difference in packet sending success rate between the link with the highest packet sending success rate and the link with the second highest packet sending success rate among at least some of the links reaches a preset difference, the packet sending is determined The proportion of packets sent in the queue to the link with the highest packet sending success rate among at least some of the links is 100%.

First, the packet sending success rate of each link needs to be counted in real time. At the same time, the length of data packets in the packet sending queue needs to be monitored in real time. If the length of the data packets currently accumulated in the packet sending queue is less than the data length threshold (1000 in this example), and the link with the highest packet sending success rate among at least some links (in this example, at least 3 links) is the same as the packet sending success rate, When the difference in packet sending success rate between the links with the next lowest rate reaches the preset difference (20% in this example), it is determined that the data packets in the packet sending queue are in at least some links with the highest packet sending success rate. The proportion of outsourcing is 100% (100% in this example). In this case, it can be considered that the data packets in the packet sending queue are more important and need to be transmitted preferentially through the link with the highest packet sending success rate. Therefore, all data packets in the packet sending queue are assigned to the link with the highest packet sending success rate for transmission to ensure that these data packets can be transmitted to the target node more reliably.

At the same time, factors such as the length of data packets accumulated in the queue, the number of available links, and packet sending capabilities can be comprehensively considered to optimize the sending of data packets. Specifically, when there is a long accumulation of data packets in the queue, a large number of available links, and a large difference in the packet sending capabilities of each link, the optimal multi-link packet sending ratio combination can be calculated through an optimization algorithm to maximize the number of packets sent. Reduce transmission delay and improve transmission efficiency. This optimization method can produce significant results in practical applications, especially when large amounts of data need to be transmitted efficiently. On the other hand, when the accumulation of data packets in the queue is small and the packet sending capabilities of each link are greatly different, try to use a single link with stronger packet sending capability to complete the sending task. This can avoid the delay caused by multi-link sending. Increased and unnecessary overhead. In this case, the possibility of using multiple links is less, so the performance improvement is also limited. For example, a single link with strong packet sending capability can be the link with the highest packet sending success rate. By comprehensively considering the above factors and adopting corresponding optimization strategies, more efficient and reliable data transmission can be achieved, while transmission delays can be minimized and overall performance can be improved. This intelligent data transmission mechanism is crucial for modern network applications, especially in scenarios with large-scale, high concurrency and high real-time requirements. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered and the optimal link for data transmission needs to be selected after comprehensive weighing.

In some embodiments, the communication status information includes the backoff waiting time of each link;

Determining, based on at least one of the data packet status information and the communication status information of each link in the plurality of links, that the data packet in the packet sending queue is in at least part of the plurality of links. The proportion of packets sent corresponding to each link in the link includes: based on the back-off waiting time of each link, in order from short to long of the back-off waiting time of each link in at least some of the links, The packet sending ratio is allocated correspondingly from large to small, wherein the link with the shortest backoff waiting time among the at least some links is allocated the largest packet sending ratio.

For example, three links are pre-selected as at least part of the links used to transmit data packets. Next, one needs to predict the performance of these selected links over a future period of time. Since the channel competition factor usually has a certain time duration (for example, the time window is 5-10 minutes), the change in the backoff waiting time within this time window can be used to predict the link performance in the future. For example, if the backoff wait time of a link has remained below 10 milliseconds in the last 5 minutes, it can be predicted that the performance of this link will be relatively stable in the future. Then, the proportion of data packets sent is allocated based on the predicted link performance. Since the longer the backoff waiting time is, the lower the duty cycle is when the link can be used as Tx (send data). Therefore, it is speculated that the link will take longer to complete data transmission, and try to allocate less data to the link. The proportion of packages issued.

First, the backoff waiting time of each link needs to be counted in real time. Then, sort according to the backoff waiting time of each link, and select at least some links from short to long. In this example, the link with the shortest backoff waiting time is selected as the link with the highest priority, and then other links are selected in order of backoff waiting time. Next, according to the backoff waiting time of each link, in order from short to long, the packet sending proportion is allocated from large to small. In this example, the total packet sending ratio is divided into three parts, and the corresponding packet sending ratio is allocated according to the backoff waiting time of each link. For example, if the backoff wait time of the first link is 2 milliseconds, the proportion of packets allocated to this link is 60%; if the backoff wait time of the second link is 5 milliseconds, then the proportion of packets allocated to this link is 5 milliseconds. The packet sending ratio is 30%, and by analogy, if the backoff waiting time of the second link is 10 milliseconds, the packet sending ratio allocated to this link is 10%. In this way, the sending of packets can be optimized based on the backoff wait time of each link. The shorter the backoff waiting time is, the higher the duty cycle of the link can be used to transmit data, so it can be inferred that the link can complete data transmission faster. Therefore, try to allocate the link with the shorter backoff waiting time to send more data packets to make full use of its transmission advantages. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered and the optimal link for data transmission needs to be selected after comprehensive weighing.

For example, when the accumulation of data packets in the queue is small and the packet sending capabilities of each link are greatly different, try to use a single link with stronger packet sending capability to complete the sending task. This can avoid the increase in delay and delay caused by multi-link sending. Unnecessary overhead. In this case, the possibility of using multiple links is small, so the performance improvement is also limited. For example, a single link with strong packet sending capability can also be the link with the shortest back-off waiting time. Therefore, it can also back-off and wait when the length of the data packets currently accumulated in the packet sending queue is less than the data length threshold, and at least part of the link When the difference in the shortest back-off waiting time between the link with the shortest time and the link with the next longest back-off waiting time reaches the preset time difference, it is determined that the data packet in the packet sending queue has the shortest back-off waiting time in at least part of the link. The proportion of packets sent in the link is 100%.

In some embodiments, the communication status information includes the packet sending success rate of each link and the backoff waiting time of each link;

Determining, based on at least one of the data packet status information and the communication status information of each link in the plurality of links, that the data packet in the packet sending queue is in at least part of the plurality of links. The proportion of packets sent corresponding to each link in , including:

If the link with the highest packet sending success rate among the at least part of the links is the first link, and the link with the shortest backoff waiting time among the at least part of the links is the first link, then the first link The link allocates the largest proportion of first packets sent; or

If the link with the highest packet sending success rate among the at least part of the links is the second link, and the link with the shortest backoff waiting time among the at least part of the links is the third link, then for the second link Allocate the largest second packet sending ratio simultaneously with the third link;

Wherein, the first contracting proportion is greater than the second contracting proportion.

For example, the evaluation is based on the packet sending success rate and backoff waiting time of each link. If the link with the highest packet sending success rate among at least some of the links is the first link, and the link with the shortest backoff waiting time among at least some of the links is also the first link, then the largest first link will be allocated to the first link. Proportion of outsourcing. This means that the first link will have the highest weight in data transmission, and the transmission performance and availability of this link are predicted to be relatively high.

On the other hand, if the link with the highest packet sending success rate among at least some of the links is the second link, and the link with the shortest backoff waiting time among at least some of the links is the third link, then the second link and The third link is also allocated the largest proportion of second packets. This means that the second and third links will have the highest weight in data transmission, since both links are predicted to have relatively high transmission performance, although their backoff waiting times may be slightly different.

In addition, the proportion of the first contract and the proportion of the second contract can be adjusted according to the demand for the proportion of the contract in different scenarios. For example, in some cases, it may be preferable to increase the proportion of the first packet sending to maximize the transmission advantage of the first link; in other cases, it may be preferable to utilize both the second link and the third link. Because of the advantages of the road, the proportion of the second package is set to be larger. It should be noted that this is just a simple example, and the actual data transmission network may be more complex. In addition, other factors need to be considered and the optimal link for data transmission needs to be selected after comprehensive weighing.

Step 130: Based on the packet sending proportion corresponding to each link in the at least part of the links, send the data packets in the packet sending queue to the second electronic device through the at least part of the links.

As shown in Figure 3, the first electronic device 10 can use the MLO mechanism of Wi-Fi 7, and multiple links for communication interaction can be established between the first electronic device 10 and the second electronic device 20, for example, The links can be 6GHz link 1, 5GHz link 2 and 2.4GHz link 3. Each time the first electronic device 10 receives a notice from the upper layer and is ready to send a data packet, it makes a real-time decision on the number of packets sent by the link based on the packet sending proportion decision-making mechanism provided by the data packet allocation method of the embodiment of the present application. The goal is to reach the lowest total sending delay and successfully send all data packets in the packet sending queue to the second electronic device 20.

For example, different packet sending ratios can be assigned to each link based on the length of data packets currently accumulated in the packet sending queue and the interference and competition conditions existing on each link. For example, link 1 and link 2 have low interference and contention, so each is allocated 40% of the packet sending ratio; link 3 has moderate interference and contention, so it is allocated 20% of the packet sending ratio. For example, the higher the packet sending success rate, the lower the interference situation. The shorter the backoff wait time, the lower the contention situation.

Next, the packet sending queue of the data packet to be sent is stored in the first electronic device 10 . The first electronic device 10 allocates the data packets in the packet sending queue to each link according to the packet sending ratio of each link, and sends them according to the packet sending ratio of each link. For example, if there are 10 data packets to be sent in the packet sending queue, link 1 will send 4 data packets, link 2 will send 4 data packets, and link 3 will send 2 data packets.

During the process of sending data packets, if a link fails or transmission is interrupted, the first electronic device 10 will redistribute the sending of data packets according to a preset fault recovery mechanism. For example, if link 2 fails, the first electronic device 10 will suspend the transmission of link 2 and redistribute the data packets originally intended to be sent by link 2 to link 1 and link 3.

In this way, based on the packet sending proportion corresponding to each link, sending the data packets in the packet sending queue to the second electronic device 20 through at least part of the link can effectively utilize the transmission capability and reliability of each link, and at the same time It ensures reliable transmission of data packets and achieves the lowest total sending delay, thereby increasing bandwidth and reducing power consumption.

All the above technical solutions can be combined in any way to form optional embodiments of the present application, and will not be described again one by one.

The embodiment of the present application is applied to the first electronic device. When there are multiple links for communication and interaction between the first electronic device and the second electronic device, and a data packet sending request is received, the data packet status information and Communication status information of each link in the multiple links; determine whether the data packet in the packet sending queue is in the multiple links according to at least one of the data packet status information and the communication status information of each link in the multiple links. Based on the packet sending proportion corresponding to each link in at least part of the link, send the data packet in the packet sending queue to the second electronic device through at least part of the link . The embodiments of this application can appropriately allocate the proportion of packets sent according to the capabilities of each underlying link to avoid the waste of better-quality link capabilities and overloading of poor-quality links in random environmental interference scenarios. This optimizes transmission performance and reduces power consumption. In addition, the embodiments of the present application can also dynamically adjust the sending strategy of data packets according to the real-time status of the link, making data transmission more flexible and efficient.
