FIG1 is a flow chart of a first embodiment of a method for optimizing network communication provided by the present application. As shown in FIG1 , the method may include:

S101. Determine the network transmission nodes between the client and the access layer device, and the status information of the network transmission nodes, wherein the network transmission nodes include firewalls, switches, and core layer devices, and the status information of the network transmission nodes includes bandwidth utilization and data packet loss rate.

Among them, the client is used to send different business request information so that the network architecture can determine the corresponding network information transmission channel according to different business request information, and send the client's network traffic information to the access layer device through the network information transmission channel. Among them, the network information transmission channel includes multiple network transmission nodes, and each network transmission node has a corresponding backup network transmission node to ensure that when the current network transmission node fails, the backup network transmission node can take over the data information of the current network transmission node to continue communication.

Optionally, before determining the network transmission node between the client and the access layer device, and the status information of the network transmission node, the method further includes:

Receive business data information sent by the client, where the business data information represents business type information and network traffic speed information sent by the client;

Determine the sampling frequency of collecting status information according to business data information;

According to the sampling frequency, the network transmission nodes between the client and the access layer device are sampled to obtain the status information of the network transmission nodes.

Among them, the status information of the network transmission node is the key information that characterizes whether the current network transmission node meets the client's business data transmission requirements. When transmitting network information, checking and predicting the status information of each network transmission node in advance can greatly reduce the failure rate of network communication and ensure the efficiency and reliability of the network architecture.

For example, after receiving the business data information sent by the client, the business type information and network traffic data information contained in the business data information are analyzed to determine the business requirements for data transmission time or the network traffic transmission speed corresponding to different business types; according to the business requirements for data transmission time or the network traffic transmission speed, the sampling frequency for collecting network transmission node status information can be set; according to the sampling frequency, the network transmission nodes that are performing data transmission can be sampled in real time and regularly, so as to obtain the status information of each network transmission node when it is working, so as to ensure that the fault information in the network transmission node can be discovered in time, thereby completing the subsequent replacement of the network transmission node and realizing efficient communication of network data.

S102: Determine a target network transmission node among the network transmission nodes according to the status information of the network transmission nodes and a preset status threshold.

The preset status threshold refers to status information that is determined based on the client service data information obtained in the above steps and meets the service data transmission requirements. The preset status threshold includes a bandwidth utilization threshold and a data packet loss rate threshold.

Determine the bandwidth requirements and data transmission efficiency requirements of each client service during network traffic transmission based on the service data information sent by the client received by the user plane;

According to the above bandwidth requirements and data transmission efficiency requirements, determine the bandwidth utilization threshold and data packet loss rate threshold that meet the client service data transmission requirements, that is, the preset state threshold;

Dividing the above preset state threshold into three intervals, namely a first threshold interval, a second threshold interval, and a third threshold interval;

The status level of each network transmission node is determined according to different threshold intervals. When the working status of the current network transmission node is in the first threshold interval, it is determined that the data transmission efficiency of the current network transmission node meets the business needs of the client, and the current network transmission node status is set to normal; when the working status of the current network transmission node is in the second threshold interval, it is determined that the data transmission efficiency of the current network transmission node meets the business needs of the client, but a failure may occur during the continued data transmission process, thereby failing to meet the business needs of the client, and the current network transmission node status is set to a warning state; when the working status of the current network transmission node is in the third threshold interval, it is determined that the data transmission efficiency of the current network transmission node cannot meet the business needs of the client, and the current network transmission node status device failure is set;

Corresponding backup or processing strategies are set for the above-mentioned different node states. When the node state is normal, the current network transmission node maintains the current state and the backup network transmission node is in standby state; when the node state is a warning, some functions of the backup network transmission node can be started, and preparations can be made to switch traffic to the backup network transmission node; when the node state is a serious warning or failure, the backup network transmission node is started immediately, all traffic is switched to the backup network transmission node, and an alarm is triggered to notify the network administrator.

Through the above mechanism, the backup or processing strategy can be reasonably set according to the status threshold and status classification of the network transmission node to ensure the stable operation of the network communication architecture and to be able to respond and handle abnormal situations in a timely manner.

Optionally, before determining the target network transmission node among the network transmission nodes according to the state information of the network transmission nodes and a preset state threshold, the method further includes:

Determine the service type information of the client according to the service data information sent by the client;

According to the service type information, determine the requirements of each service on network bandwidth utilization and data packet loss rate;

Determine the bandwidth utilization threshold and the data packet loss rate threshold according to the network bandwidth utilization requirement and the data packet loss rate requirement;

A preset state threshold is obtained according to a bandwidth utilization threshold and a data packet loss rate threshold.

Among them, the bandwidth utilization threshold can be determined based on different network information, for example, based on the network type, different bandwidth utilization standards corresponding to the corresponding network are determined according to different types of network requests sent by the client, thereby determining the bandwidth utilization threshold; or, the bandwidth utilization threshold is determined according to the demand for network applications sent by the client, thereby ensuring that the network can meet the performance requirements of the application.

In addition, the data packet loss rate threshold can be determined based on the client's requirements for the network service level or the load conditions in the communication link; for example, the corresponding data packet loss rate threshold can be set according to the data packet loss rate requirements specified in the client service level agreement; or the appropriate packet loss rate threshold can be determined based on the tolerance of different client applications to the data packet loss rate; or the data packet loss rate can be monitored in real time through a network monitoring tool, and the threshold can be adjusted according to actual conditions to ensure that the network performance reaches the expected level; or a reasonable data packet loss rate threshold can be set considering the load conditions of network devices and links, as well as the possibility of network congestion.

Among them, after determining the preset status threshold, the status information collected regularly can be compared with the preset status threshold to determine the status information that does not meet the preset status threshold requirement in the status information collected on time, and determine that the network transmission node that outputs the status information is a faulty node, so as to timely discover information in the network that cannot meet the bandwidth utilization threshold or the data packet loss rate threshold, and take corresponding measures to adjust the network configuration and optimize the network performance to ensure that the network can meet the requirements.

For example, the regularly collected bandwidth utilization information and data packet loss rate information are compared with the preset threshold value. If the bandwidth utilization within a certain sampling period exceeds the preset threshold value or the data packet loss rate exceeds the preset threshold value, it means that the current network transmission node cannot meet the requirements. At this time, it is necessary to determine the exact time period when the data transmission failure occurred within the sampling period, and perform a secondary state comparison of the data status information transmitted within the exact time period with the preset state threshold to determine the exact data point where the data transmission failure occurred within the time period, and mark the data information between the data points so that when the network transmission node is switched later, the data information between the data points can be synchronized to the backup network transmission node, thereby avoiding synchronizing the failed data information to the backup network transmission node.

In addition, for network transmission information that exceeds the threshold, it can be marked with color or alarm, so that the network problem can be intuitively displayed in the monitoring interface or report, or a real-time alarm or notification mechanism can be set up to send alarm information to the network administrator in time so that timely measures can be taken to solve the network problem; in addition, for network transmission information that exceeds the threshold, it is necessary to further analyze and troubleshoot the cause of the problem, which may include network congestion, equipment failure, link quality and other issues.

Wherein, if the status comparison result indicates that the status information does not meet the preset status threshold, after determining the target network transmission node corresponding to the status information, the method further includes:

According to the target network transmission node, determining the node type of the target network transmission node;

Determine the backup network transmission node and the data synchronization protocol according to the node type of the target network transmission node, where the data synchronization protocol is a protocol for synchronizing data information between the target network transmission node and the backup network transmission node;

According to the data synchronization protocol, the data information of the target network transmission node is synchronized to the backup network transmission node.

Among them, after determining the network transmission fault node that cannot meet the preset status threshold requirements, it is necessary to switch the network transmission fault node to a network transmission node that meets the preset status threshold requirements. For example, after determining the network transmission fault node, quickly formulate and implement an effective fault recovery strategy, including automatically switching to a backup network transmission node, promptly notifying the network administrator and other steps to minimize the time and impact of network interruption.

Optionally, when the target network transmission node is a firewall, determining the backup network transmission node and the data synchronization protocol according to the node type of the target network transmission node includes:

Determine the backup firewall corresponding to the firewall and the heartbeat line protocol for data synchronization between the firewall and the backup firewall according to the node type of the target network transmission node;

Determine the backup network transmission node and data synchronization protocol based on the backup firewall and heartbeat protocol.

Among them, when the target network transmission node with transmission failure is switched to the backup network transmission node, it is necessary to determine the node type of the target network transmission node and the data synchronization protocol between the network transmission failure node and the backup network transmission node; for example, when the network transmission node with data transmission failure is a firewall, it can be determined that the backup network transmission node corresponding to the firewall is the backup firewall, and the heartbeat line protocol for data synchronization with the backup firewall; the backup firewall can regularly monitor the received heartbeat signal of the main firewall through the heartbeat line protocol to confirm the status of the main firewall. If the backup firewall does not receive the heartbeat information of the main firewall within a certain period of time, it will be considered that the main firewall has failed. At this time, the backup firewall takes over the function of the main firewall according to the data information regularly sent by the main firewall between the heartbeat information is not sent, and starts to receive traffic from the network. At this time, the backup firewall becomes the new main firewall; in addition, when the original main firewall is repaired, it can also be reconfigured as a backup firewall and wait for the next switch.

Optionally, when the target network transmission node is a switch, determining the backup network transmission node and the data synchronization protocol according to the node type of the target network transmission node includes:

Determine, according to the node type of the target network transmission node, a backup switch connected to the switch stack and a stacking protocol for data synchronization between the switch and the backup switch;

The backup network transmission node and the data synchronization protocol are determined according to the backup switch and the stacking protocol.

Among them, when the network transmission node with data transmission failure is a switch, it can be determined that the backup network transmission node connected to the switch stack is the backup switch, and the stacking protocol for data synchronization between the backup switch and the backup switch; the backup switch can regularly monitor the status information received from the main switch through the stacking protocol, including port status, virtual local area network information (English: Virtual Local Area Network, abbreviated as: VLAN), routing table, etc., to confirm the status of the main switch. If the backup switch does not receive the status information of the main firewall within a certain period of time, it will be considered that the main switch has failed. At this time, the backup switch takes over the function of the main switch according to the data information regularly sent by the main switch between the status information is not sent, and starts to receive data information from the firewall. At this time, the backup switch becomes the new main switch; in addition, when the original main switch is repaired, it can also be reconfigured as a backup switch and wait for the next switch.

Optionally, when the target network transmission node is a core layer device, determining the backup network transmission node and the data synchronization protocol according to the node type of the target network transmission node includes:

Determine, according to the node type of the target network transmission node, a backup core layer device connected to the core layer device through cross-device aggregation, and a link aggregation protocol for data synchronization between the core layer device and the backup core layer device;

Determine the backup network transmission node and data synchronization protocol based on the backup core layer device and the link aggregation protocol.

Among them, when the network transmission node where data transmission failure occurs is a core layer device, the backup network transmission node that is aggregated and connected to the core layer device across devices can be determined as the backup core layer device, as well as the link aggregation control protocol for data synchronization with the backup core layer device; the backup core layer device can regularly monitor the status information received from the main core layer device through the link aggregation control protocol, including configuration information, VLAN information, routing table, etc., to confirm the status of the main core layer device. If the backup core layer device does not receive the status information of the main core layer device within a certain period of time, it will be considered that the main core layer device has failed. At this time, the backup core layer device takes over the function of the main core layer device according to the data information regularly sent by the main core layer device between the status information being not sent, and starts to receive data information from the stacked switches. At this time, the backup core layer device becomes the new core layer device; in addition, after the original main core layer device is repaired, link aggregation and data synchronization can be re-performed to ensure that the network is restored to its original working state.

S103. Replace the target network transmission node with a backup network transmission node to carry out network communication between the client and the access layer device. When the target network transmission node is a firewall, the backup network transmission node is a backup firewall that establishes a synchronous association relationship with the firewall according to the heartbeat protocol; when the target network transmission node is a switch, the backup network transmission node is a backup switch that is connected to the switch stack according to the stacking protocol; when the target network transmission node is a core layer device, the backup network transmission node is a backup core layer device that is aggregated across devices with the core layer device according to the link aggregation control protocol.

After replacing the target network transmission node with a backup network transmission node to perform network communication between the client and the access layer device, the method further includes:

The node state of the target network transmission node is adjusted to a maintenance state to perform fault analysis and optimization on the target network transmission node.

Among them, in the process of switching the actual network transmission node, appropriate switching strategies and mechanisms can be selected according to the specific needs and architecture of the network to ensure that the network can respond to the situation where the node or device cannot meet the threshold in a timely and effective manner, and ensure the normal operation and performance of the network. For example, through load balancing technology, after receiving the network traffic information of the client, the network traffic can be automatically shared to multiple nodes or devices, so as to avoid performance problems caused by single point failures, that is, when a node or device cannot meet the threshold, the load balancing strategy can be dynamically adjusted to redistribute the traffic to other normal nodes or devices; or, when it is found that a node or device cannot meet the threshold, the network administrator can manually intervene and switch the traffic to the backup node or device until the original node or device returns to normal; secondly, an effective fault recovery strategy can be formulated and implemented, including steps such as rapid fault detection, automatic switching to the backup node or device, and timely notification of the network administrator, so as to minimize the network interruption time and impact; in addition, the network transmission nodes or devices can be regularly inspected and maintained, and aging or faulty devices can be replaced in time to preventively improve the stability and reliability of the network, thereby improving the security and reliability of the network architecture to a certain extent.

The network communication optimization method provided in the present application can be achieved by determining the network transmission nodes between the client and the access layer device, and the status information of the network transmission nodes, wherein the network transmission nodes include firewalls, switches, and core layer devices, and the status information of the network transmission nodes includes bandwidth utilization and data packet loss rate; determining the target network transmission node in the network transmission node according to the status information of the network transmission node and a preset status threshold; replacing the target network transmission node with a backup network transmission node to perform network communication between the client and the access layer device, wherein when the target network transmission node is a firewall, the backup network transmission node is a backup firewall that establishes a synchronization association relationship with the firewall according to a heartbeat protocol; when the target network transmission node is a switch, the backup network transmission node is a backup switch that is connected to the switch stack according to a stacking protocol; when the target network transmission node is a core layer device, the backup network transmission node is a backup core layer device that is aggregated across devices with the core layer device according to a link aggregation control protocol, thereby solving the problems of single point failure and poor availability in the network architecture in the prior art.

FIG2 is a flow chart of a second embodiment of the network communication optimization method provided by the present application. As shown in FIG2, the flow of the method includes:

S201. Receive business data information sent by a client.

Among them, according to the service request information and data flow information sent by the client received by the user data plane, the service type of each service and the requirements of each service for network flow transmission are determined; according to each service type and network flow transmission requirements, the internal configuration information of each network information transmission device in the device network architecture can be further obtained.

S202: Determine a target network information transmission device according to the business data information.

Among them, according to the business data information sent by the client, the business type of each business can be determined; according to the business type of each business, the virtual private network (English: Virtual Private Network, referred to as: VPN) required for data transmission of each business can be determined; according to each VPN, the various VPNs that need to be bound inside the firewall in the network communication architecture can be determined to ensure that each business of the client can be isolated from each other and do not affect each other, thereby ensuring the security of each business; according to each VPN, the virtual router redundancy protocol information (English: Virtual Router Redundancy Protocol, referred to as: VRRP) of the firewall is determined, and the main firewall and the backup firewall are set. The working priority of the main firewall is higher than the working priority of the backup firewall. The main firewall and the backup firewall synchronize data through the heartbeat line in the VRRP to ensure that when the main firewall fails, the backup firewall can take over the main firewall and continue to work; the main firewall and the backup firewall are collectively referred to as the first target network information transmission device.

Secondly, the business data information sent by the client needs to be transmitted to the switch part after being diverted and detected by the firewall. The switch configures the corresponding VLAN LAN channel for each business according to the business information under different VPNs sent by the firewall to ensure that each business is sent to the corresponding bearer network; wherein, the switch part is configured as a stacked switch structure, by stacking two switches to logically become one switch, thereby achieving a redundancy effect; the stacked switch is the second target network information transmission device.

In addition, the business data information needs to be sent to the core layer device after passing through the stacked switch. In order to ensure the accuracy of the business data information transmission, the core layer device and the stacked switch can be connected by link aggregation; for example, the interfaces of the first switch and the second switch in the stacked switch are bound to an aggregation group, and the aggregation group should be configured as a switch mode, and the first core layer device and the second core layer device are set.

FIG3 is a schematic diagram of the network communication architecture structure provided in an embodiment of the present application, as shown in FIG3 .

User plane function (UPF) is a user plane network element defined by 5G, which is mainly responsible for processing the functions of the user data plane.

Routing and Switching Gateway (RSG) is a core layer device in the network. It is responsible for routing and switching business data in the network, connecting different network nodes and terminal devices, and ensuring smooth data transmission and exchange.

The Customer Side Gateway (CSG) is an access layer device in the network, used to connect the customer-side device and the operator's network, providing service access and data transmission functions.

Pseudo Wire (PW) is the most basic channel for carrying transmission services in communication networks. PW technology enables the network to provide multiple access services while reducing the cost and complexity of traditional network upgrades.

The process of determining the target network information transmission device is as follows: when the service data information sent by the client can be accurately sent to the bearer network, the transmission direction of the service data information is: mobile terminal, base station, UPF, main firewall, stack switch, RSG1, CSG, customer network;

When the link from the main firewall to switch 1 is interrupted, the firewall master-slave and VRRP master-slave switch occurs, and the transmission direction of service data information is: mobile terminal, base station, UPF, standby firewall, stack switch, RSG1, CSG, customer network;

When the link from RSG1 to switch 1 is interrupted, the PW primary and backup are switched, and the transmission direction of service data information is: mobile terminal, base station, UPF, main firewall, stack switch, RSG2, CSG, customer network;

When a fault occurs on the bearer network and causes PW switching, the transmission direction of service data information is: mobile terminal, base station, UPF, main firewall, stack switch, RSG2, CSG, customer network;

When the link from the main firewall to switch 1 is interrupted, and the link from RSG1 to switch 1 is interrupted at the same time, the transmission direction of service data information is: mobile terminal, base station, UPF, standby firewall, stack switch, RSG2, CSG, customer network;

When the link from the standby firewall to switch 2 is interrupted, and the link from RSG2 to switch 2 is interrupted at the same time, the transmission direction of service data information is: mobile terminal, base station, UPF, main firewall, stack switch, RSG1, CSG, customer network;

When the link from the main firewall to switch 1 is interrupted, and the link from RSG2 to switch 2 is interrupted at the same time, the transmission direction of service data information is: mobile terminal, base station, UPF, standby firewall, stack switch, RSG1, CSG, customer network;

When the link from the backup firewall to switch 2 is interrupted and the link from RSG1 to switch 1 is interrupted, the transmission direction of the service data information is: mobile terminal, base station, UPF, main firewall, stack switch, RSG2, CSG, customer network.

Therefore, as long as two firewalls, two switches, two RSGs, or two PWs on the same plane do not fail at the same time, the user's data transmission will not be affected. Through the device's own fast detection and switching mechanism, the user can be completely unaware in ordinary business scenarios, ensuring the user experience and improving the high availability of the dedicated line.

The network communication optimization method provided in the embodiment of the present application can achieve complete user-imperceptible performance in ordinary business scenarios through the rapid detection and switching mechanism of the device itself, thereby improving the stability and redundancy of customer dedicated lines and ensuring a good network experience for users.
