Description

technical field

Background technique

With the rapid development of cloud platform technology, more and more Internet companies integrate resources and provide them to the majority of users in the form of cloud platforms. The core concept of the cloud platform is the Internet as the center, so that everyone who uses the Internet can use the huge computing resources and data on the network. Therefore, the use of cloud platforms has high requirements on the transmission quality of the network. Currently, a commonly used network transmission protocol mainly adopts a stable Transmission Control Protocol (TCP) for data transmission. The stability of the TCP protocol is mainly reflected in: Before transmitting data, a connection is established through a three-way handshake. In the process of data transmission, there will also be acknowledgment, retransmission, congestion control and other mechanisms to ensure data transmission. After the transfer is complete, the connection is disconnected to save system resources.

However, since the above transmission mechanism takes some time, and each device using cloud platform technology needs to maintain transmission connections, each transmission connection needs to occupy system resources, so the TCP protocol is used for cloud platform data. Transmission will have problems such as high delay, high jitter, and high packet loss rate, especially in the case of poor network quality, which may cause problems such as operation freezes or blurred images, resulting in poor user experience.

In order to facilitate understanding of the solution proposed in this application, the network architecture involved in this application is first introduced. Referring to FIG. 1 , an architecture diagram of a communication system provided by an embodiment of the present application. Including terminal equipment and cloud platform server. The terminal device may also be understood as a client of the cloud platform.

The terminal device shown in FIG. 1, also known as a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., is a device that provides voice and/or data connectivity to users, for example, has wireless Connectivity-enabled handheld devices, in-vehicle devices, etc. At present, some examples of terminals are: mobile phone (mobile phone), tablet computer, notebook computer, palmtop computer, mobile Internet device (Mobile Internet Device, MID), wearable device, virtual reality (Virtual Reality, VR) device, augmented reality (Augmented Reality, AR) equipment, wireless terminals in industrial control (Industrial Control), wireless terminals in self-driving (self driving), wireless terminals in remote medical surgery (remote medical surgery), smart grid (smart grid) wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc.

The functions of the cloud platform server shown in FIG. 1 may be implemented by one server or by a server cluster, which is not limited in this application. The cloud platform server may include a processor, a hard disk, a memory, a system bus, etc., to receive messages from terminal devices, and to process the received messages accordingly.

Optionally, the data transmission between the terminal device and the cloud platform server may adopt a Transmission Control Protocol (Transmission Control Protocol, TCP), a User Datagram Protocol (User Datagram Protocol, UDP), or a File Transfer Protocol (File Transfer Protocol, FTP) etc. agreement. It should be noted that the above FIG. 1 is only an example, and the embodiments of the present application do not specifically limit the number of terminal devices and cloud platform servers included in the communication system.

In the related art, in order to ensure the stability and success rate of data transmission, when the cloud platform is used, the TCP protocol is generally used for data transmission between the cloud platform server and the terminal device. Specifically, before data transmission is performed, a communication connection is established through a three-way handshake. In the process of data transmission, the TCP transmission protocol also includes mechanisms such as acknowledgment, window, retransmission and congestion control to ensure the success rate of data transmission. After the data transfer is completed, the connection can also be disconnected to save transfer resources. However, it is precisely because of the above-mentioned mechanisms that the use of the TCP protocol for data transmission will cause a relatively high transmission delay, resulting in problems such as operation freezes and blurred images, which affect the user experience.

In view of this, the embodiments of the present application provide a method and device for data transmission based on a cloud platform, which determines the transmission protocol used for transmission by combining network quality, thereby improving the efficiency of data transmission and avoiding operation freezes or images. Blur and other issues that affect the user experience.

In order to facilitate the understanding of the data transmission method based on the cloud platform provided by the embodiment of the present application, referring to FIG. 2 , a flowchart of the data transmission method based on the cloud platform provided by the embodiment of the present application specifically includes:

201. The terminal device acquires network quality requirements corresponding to at least two pre-stored transmission protocols respectively.

Optionally, at least two transmission protocols may be pre-configured in the terminal device, and each transmission protocol may correspond to a network quality requirement. For example, taking the TCP protocol and the UDP protocol as examples, since the TCP protocol has higher requirements on network stability, a higher network quality requirement can be configured for the TCP protocol. Since the UDP protocol does not need to establish a communication connection and directly transmits data, it has lower network requirements, so a lower network quality requirement can be configured for the UDP protocol.

202. Determine the transmission protocol corresponding to the highest network quality requirement among the network quality requirements that the current network quality conforms to.

Optionally, the network quality may be determined according to relevant parameters of various businesses currently performed by the terminal device. For example, the relevant parameters may include parameters such as service access success rate, service access delay, service download rate, service download delay, service upload rate, service upload delay, signal quality or service interruption rate. The terminal device may determine the current network quality according to the above parameters, and may determine the highest network quality requirement among the pre-stored network quality requirements that the current network quality meets.

As an example, it is assumed that the current network quality satisfies network quality requirement A, network quality requirement B, and network quality requirement C among the multiple network quality requirements stored in the terminal device. And, the network quality requirement A is the highest requirement among the three network quality requirements. Then the terminal device can obtain the transmission protocol corresponding to the network quality requirement A.

203, the terminal device sends the data to be transmitted to the cloud platform server by using the determined transmission protocol.

Specifically, the terminal device may use a certain transmission protocol to process the data to be transmitted, for example, use a certain transmission protocol to package, encapsulate, encrypt, and add corresponding header information to the data to be transmitted. And send the data to be transmitted after processing to the cloud platform server.

Based on the above solution, the terminal device no longer uses a fixed transmission protocol for data transmission with the cloud platform, but pre-stores multiple transmission protocols and network quality requirements corresponding to the multiple transmission protocols. Further combine the current network quality to determine which transmission protocol to use for data transmission, so as to improve data transmission efficiency without reducing the stability of data transmission as much as possible, avoid problems such as screen freezes, and improve user experience. .

It should be noted that this application does not specifically limit the transmission protocol pre-stored in the terminal device. Optionally, a transmission protocol with high stability, many transmission mechanisms, and long transmission time may be configured with higher network quality requirements. That is, when the network quality is high, a transmission protocol with high stability is adopted. Less stable transport protocols can be configured with lower network quality requirements. That is, in the case of low network quality, a transmission protocol with low stability is adopted to ensure low transmission delay.

For the convenience of description, a specific description is given below in conjunction with the TCP protocol and the UDP protocol. It should be noted that this application does not limit the transmission protocol, and other transmission protocols may also be used. For the convenience of description, only the TCP protocol and the UDP protocol are used as examples for introduction. The TCP protocol includes the process of establishing a transmission connection, various guarantee mechanisms, and disconnecting the transmission connection after the transmission is completed. Therefore, using the TCP protocol for data transmission can improve the stability and success rate of data transmission. However, since each mechanism takes a long time, there is a problem of high delay when the TCP transmission protocol performs data transmission, especially in the case of low network quality, this problem is more serious. The UDP protocol does not need to establish a transmission connection, and can directly transmit data, which takes less time, but has poor stability.

Based on this, the embodiment of the present application proposes to use the TCP transmission protocol for data transmission in a scenario with high network quality. In the case of low network quality, the UDP transmission protocol is used for data transmission. In order to facilitate understanding, the process of data transmission between the TCP protocol and the UDP protocol is briefly introduced first.

First, the process of transmitting data with the TCP protocol is introduced:

Step 1: Establish a TCP communication connection through a three-way handshake.

For the first handshake, the terminal device sends a connection request message to the cloud platform server. The message may include the data communication initial sequence number of the terminal device. After the request is sent, the terminal device can enter the SYN-SENT state.

In the second handshake, the cloud platform server receives the connection request and returns the response information to the terminal device. The response information includes the initial sequence number of the cloud platform server for data communication. After the response information is sent, the cloud platform server enters the SYN-RECEIVED state.

In the third handshake, the terminal device receives the response information and returns a confirmation message to the cloud platform server. The terminal device enters the ESTABLISHED state after sending the confirmation message, and the cloud platform server also enters the ESTABLISHED state after receiving the confirmation message. So far, the TCP communication connection is established successfully.

Step 2, using the TCP protocol to process the data to be transmitted and transmit the data to be transmitted.

Optionally, the data to be transmitted may be encapsulated, encrypted, compressed, and a packet header added by using the TCP protocol. And send the processed data to be transmitted to the cloud platform server. In the transmission process, mechanisms such as acknowledgment, window, retransmission, and congestion control are used to ensure the success rate of data transmission.

Step 3: After the transmission is completed, disconnect the TCP communication connection.

Optionally, the TCP communication connection can be disconnected through a four-way handshake.

For the first handshake, the terminal device sends a connection release request to the cloud platform server after the data transmission is completed.

In the second handshake, the cloud platform server receives the connection release request and notifies the application layer to release the TCP communication connection. And return an acknowledgement character (Acknowledgement Character, ACK) feedback packet to the terminal device to indicate that the TCP communication connection has been released and no longer receive data packets from the terminal device. The cloud platform server can enter the CLOSE_WAIT state after returning the ACK feedback packet.

In the third handshake, if the cloud platform server still has data to be sent to the terminal device at this time, the data transmission will continue until the data transmission is completed, and the cloud platform server will enter the LAST-ACK state.

In the fourth handshake, the terminal device enters the CLOSED state if it does not receive data from the cloud platform server within the set time period after sending the connection release request. At this point, the disconnection of the TCP communication connection is completed.

Next, the process of UDP protocol data transmission is introduced:

When the terminal device uses the UDP protocol for data transmission, it does not need to establish a communication connection, but only needs to use the UDP protocol to process the data to be transmitted, and the processed data to be transmitted can be directly sent to the cloud platform server.

In general, when the UDP protocol is used to process the data to be transmitted, a UDP header can be added to the data to be transmitted. However, the stability and success rate of this kind of sending data are relatively low. In order to solve such problems, the embodiments of the present application propose to add timeout judgment and fast retransmission mechanisms when using the UDP protocol for data transmission, so as to ensure the success rate of data transmission. Optionally, a retransmission mechanism may be configured for the UDP protocol, which may include the retransmission time. In the process of data transmission, the red pair is retransmitted according to the retransmission time, so as to improve the reliability of data transmission.

In some embodiments, when the terminal device continues data transmission using the UDP transmission protocol, it may first determine whether the data to be transmitted is data that has already been sent. If the data to be transmitted is not the data that has already been sent, the UDP protocol is directly used to process the data to be transmitted, and the processed data to be transmitted is sent to the server of the cloud platform. If the data to be transmitted is already sent data, the retransmission mechanism configured for the UDP protocol can be used to retransmit the data to be transmitted. As an optional method, the terminal device can determine whether the time interval between the current time and the time when the data to be transmitted last time has reached the retransmission time configured for the UDP protocol, and if so, the data to be transmitted will be processed. transmit again. If not, wait until the retransmission time before retransmitting the data.

Optionally, the embodiment of the present application further proposes that the retransmission time configured for the UDP protocol may be shorter than the retransmission time configured for the TCP protocol. For example, in the Automatic Repeat-reQuest (ARQ) protocol, the retransmission time of TCP is defined as the time of the Retransmission Timeout (RTO)*2, that is, a certain distance from the last transmission. When a data reaches the RTO*2 time, and still does not receive an ACK packet from the opposite end, the data can be retransmitted. The embodiment of the present application proposes that the retransmission time configured by the UDP protocol may be configured to be RTO*1.5, or may be set to a smaller value, which is not specifically limited in the present application. In addition, the embodiment of the present application also proposes that in the case of continuous packet loss, the retransmission time can be reduced according to the number of retransmissions, so as to solve the problem of slow data transmission in the case of network congestion. improve data transmission efficiency.

In some embodiments, the retransmission mechanism included in the TCP protocol includes retransmitting all the data packets after the data packet with the smallest sequence number when a packet loss phenomenon occurs. The embodiments of the present application propose that when the UDP protocol is used for data retransmission, only the lost data packets may be transmitted, so as to reduce invalid data retransmission. In other embodiments, when the terminal device uses the UDP protocol for data transmission, the size of the sending window may also be determined according to the size of the sending buffer and the remaining receiving buffer size of the cloud platform server. In this way, congestion control is realized and the speed of data transmission is improved.

Further, after the terminal device transmits the data to the cloud platform server using the above-mentioned protocol and mechanism, the cloud platform server can process the received message according to the instruction of the message header, for example, perform operations such as unpacking and confirming the message. , and then send the processed data to the upper business layer for processing.

In some scenarios, the system shown in FIG. 1 may also be functionally divided into multiple modules, and different functional modules perform the above steps. Optionally, the terminal device side can be divided into: a protocol selection module, a processing module and an accelerated processing module. The server side of the cloud platform can be divided into: a processing module and an accelerated processing module. For convenience of description, the processing module and the accelerated processing module in the terminal device are referred to as the first processing module and the first accelerated processing module. The processing module and the accelerated processing module in the cloud platform server are referred to as the second processing module and the second accelerated processing module. As an example, reference may be made to FIG. 3 , which is a system architecture diagram provided by an embodiment of the present application. It should be noted that the above-mentioned division of modules is only an example, and the embodiment of the present application does not specifically limit the division rules of modules.

In order to further understand the solutions proposed by the embodiments of the present application, the solutions of the present application are introduced below with reference to the above-mentioned specific modules. Referring to FIG. 4 , a flowchart of a cloud platform-based data transmission method provided by an embodiment of the present application specifically includes:

401. The protocol selection module determines a protocol for transmitting the data to be transmitted according to the current network quality.

Optionally, the protocol selection module may be configured with the TCP protocol and the UDP protocol, and network quality requirements corresponding to the two transmission protocols. Further, the protocol selection module may determine the transmission protocol to be adopted according to the network quality requirements satisfied by the current network quality.

In one case, if the protocol selection module determines that the current network quality meets the network quality requirement corresponding to the TCP protocol, it may be determined that TCP is used for data transmission, and the process proceeds to step 402 .

In another case, if the protocol selection module determines that the current network quality does not meet the network quality requirements corresponding to the TCP protocol, but meets the network quality requirements corresponding to the UDP protocol, it may be determined to use the UDP protocol for data transmission, and proceed to step 403 .

It should be noted that the above agreement is only an example, and this application does not specifically limit the type and quantity of the agreement. That is, other multiple transmission protocols may also be configured in the protocol selection module.

402. The first processing module uses the TCP protocol to process the data to be transmitted, and sends the processed data to be transmitted to the second processing module.

403. The first acceleration processing module determines whether the data to be transmitted is sent data.

If so, go to step 404 .

If not, go to step 405 .

404. The first acceleration module determines whether the retransmission time corresponding to the UDP protocol is reached.

If yes, go to step 405 .

If not, step 405 is executed after waiting for the retransmission time.

405. The first acceleration module uses the UDP protocol to process the data to be transmitted, and sends the processed data to be transmitted to the second acceleration processing module.

Optionally, after receiving the data, either the second processing module or the second accelerated processing module will use a corresponding protocol to perform processing such as decapsulation of the data, and send the processed data to the upper service layer for service processing.
