Description

Technical Field

[0001] This application relates to the technical field of traffic control, and particularly to a method, device, equipment, and storage medium for optimizing the traffic of peer links in a multi-link aggregation group protocol. Background Art

[0002] With the popularization of data centers and large-scale networks, the Multi-Chassis Link Aggregation Group (MLAG) technology has become a common solution for improving network redundancy and reliability. Through the MLAG protocol, redundancy and load balancing of links between multiple switches can be achieved, enhancing network stability without reducing network performance. However, existing MLAG technologies have some defects in certain network topologies, especially in the processing of the isolation direction of peer links. Currently, the Peerlink connections between multiple switches in the MLAG protocol are mainly used for state synchronization and load balancing, but the processing of the isolation direction of Peerlink lacks flexibility, affecting the normal operation of the network. In addition, existing MLAG implementations usually ignore the isolation requirements of different network traffic, resulting in redundant traffic and performance conflicts when data flows through Peerlink. In some application scenarios, the failure or performance bottleneck of Peerlink will lead to a decline in the performance of the entire MLAG link. Therefore, how to improve the performance of peer links in the multi-link aggregation group protocol is still a problem to be solved.

[0047] It should be understood that the specific embodiments described here are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] To better understand the technical solution of this application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0049] The main solution of this application is to detect the target traffic entering the peer link of the multi-link aggregation group protocol; obtain the traffic type and traffic direction of the target traffic, and determine the priority of the target traffic according to the traffic type and the traffic direction; obtain the network load in real time, and determine the bandwidth allocation policy according to the network load and the priority to complete traffic optimization.

[0050] Currently, the Peerlink connection between multiple switches in the MLAG protocol is mainly used for status synchronization and load balancing, but it lacks flexibility in handling the isolation direction of Peerlink, which affects the normal operation of the network. In addition, existing MLAG implementations usually ignore the isolation requirements of different network traffic, resulting in redundant traffic and performance conflicts when data flows through Peerlink. In some application scenarios, the failure or performance bottleneck of Peerlink will cause the performance of the entire MLAG link to decline. Therefore, how to improve the performance of the peer link of the multi-link aggregation group protocol is still a problem to be solved.

[0051] This application performs bandwidth allocation based on the network load and the priority of the traffic in the peer link, improving the performance of the peer link of the multi-link aggregation group protocol.

[0052] Based on this, an embodiment of this application provides a traffic optimization method for the peer link of the multi-link aggregation group protocol. Refer to Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the traffic optimization method for the peer link of the multi-link aggregation group protocol of this application.

[0053] In this embodiment, the traffic optimization method for the peer link of the multi-link aggregation group protocol includes steps S10 to S30:

[0054] Step S10: Detect the target traffic entering the peer link of the multi-link aggregation group protocol;

[0055] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device or a traffic optimization device for the peer link of the multi-link aggregation group protocol that can implement the above functions. The following takes the traffic optimization device for the peer link of the multi-link aggregation group protocol as an example to illustrate this embodiment and the following embodiments.

[0056] It should be noted that a multi-link aggregation group, namely MLAG, is a network technology mainly used to improve network reliability and bandwidth. It allows two or more network devices (such as switches or routers) to form a logically aggregated link through multiple physical links, thereby providing higher throughput and redundancy. A peer link, namely Peerlink, is a key link in the MLAG configuration and is used to connect two MLAG peer switches (or other network devices). It is a direct and must-be-aggregated link used to exchange negotiation messages and transmit part of the traffic. The traffic entering the Peerlink can be detected and classified according to the traffic type and traffic direction.

[0057] Step S20: Obtain the traffic type and traffic direction of the target traffic, and determine the priority of the target traffic according to the traffic type and the traffic direction;

[0058] It can be understood that the traffic passing through the peer link of the multi-link aggregation group protocol has different types, such as data traffic, control traffic, etc. In different scenarios, the priorities of different types of traffic are also different, and the priority can be determined according to the traffic type; in addition, the traffic passing through the peer link of the multi-link aggregation group protocol can also be classified according to the traffic direction and jointly determine the priority with the traffic type. Specifically, a traffic monitoring algorithm can be used to detect and identify traffic patterns in real time. For example, the traffic flowing into a certain Peerlink may have a priority and is given preferential treatment according to the traffic type. For reference Figure 2 , Figure 2 is a schematic diagram of the network topology of the peer link of the multi-link aggregation group protocol. Figure 2 In, the function of the heartbeat link is to detect whether the device status is normal. When Host 1 sends data to Host 2, the traffic is first analyzed. If it is identified as a data traffic and it is determined that its flow direction is through the peer link from Switch A to Switch B. And the data traffic is marked as high priority to ensure that the data can pass through the idle link preferentially.

[0059] In a feasible manner, the step of determining the priority of the target traffic according to the traffic type and the traffic direction includes:

[0060] Judge whether the target traffic is data traffic according to the traffic type;

[0061] Judge whether the target traffic is in a preset direction according to the traffic direction;

[0062] Determine the target traffic with the traffic type being data traffic and the traffic direction being the preset direction as high priority.

[0063] It is understandable that in different scenarios, the criteria for determining priorities are different. For example, the target traffic with the traffic type being data traffic and the traffic direction being a preset direction can be determined as having a high priority, while other traffic is determined as having a low priority.

[0064] Step S30: Obtain the network load in real time, and determine a bandwidth allocation strategy based on the network load and the priority to complete traffic optimization.

[0065] It is understandable that after obtaining the network load and the priority, a bandwidth allocation strategy can be formulated through the network load and the priority to ensure that traffic with a high priority can be processed first. Adjust the bandwidth allocation of the Peerlink link according to the real-time network load. Allocate bandwidth for different traffic to ensure that the network bandwidth will not be overloaded and the traffic can be transmitted according to the priority.

[0066] In a feasible manner, the step of determining the bandwidth allocation strategy according to the network load and the priority includes:

[0067] Obtain the network congestion information of the peer link according to the network load;

[0068] Determine the bandwidth requirement of the target traffic according to the priority;

[0069] Determine the bandwidth allocation strategy of the target traffic according to the network congestion information and the bandwidth requirement.

[0070] It is understandable that according to the network congestion information, the traffic situation of the peerlink link can be obtained, and the bandwidth allocation can be carried out in combination with the bandwidth requirement of the target traffic, which can make full use of the peerlink link to complete traffic optimization.

[0071] In a feasible manner, after determining the bandwidth allocation strategy of the target traffic according to the network congestion information and the bandwidth requirement, it further includes:

[0072] Obtain the bandwidth usage rate of the multi-link aggregation group protocol peer link in real time;

[0073] When the bandwidth usage rate reaches a preset threshold, adjust the bandwidth allocation strategy to avoid overloading the peer link.

[0074] It is understandable that during the process of traffic passing through the Peerlink link, the bandwidth usage situation is monitored in real time. If it is found that the bandwidth usage rate of a certain link is too high, the bandwidth allocation strategy can be dynamically adjusted to ensure reasonable traffic allocation and avoid link overloading.

[0075] This embodiment detects the target traffic entering the peer link of the multi-link aggregation group protocol; obtains the traffic type and traffic direction of the target traffic, and determines the priority of the target traffic according to the traffic type and the traffic direction; obtains the network load in real time, and determines the bandwidth allocation strategy according to the network load and the priority, so as to complete traffic optimization.

[0076] In summary, this embodiment allocates bandwidth based on the network load and the priority of the traffic in the peer link, improving the performance of the peer link of the multi-link aggregation group protocol.

[0077] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as in the above-mentioned first embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 , after step S30, the traffic optimization method for the peer link of the multi-link aggregation group protocol further includes steps S301 to S303:

[0078] Step S301: Monitor the running state of the peer link of the multi-link aggregation group protocol;

[0079] It can be understood that by monitoring the running state of the peer link of the multi-link aggregation group protocol, the traffic changes in the peer link can be obtained in a timely manner, so as to perform fault handling in a timely manner.

[0080] Step S302: When the running state is traffic overload, redirect part of the target traffic to the standby link;

[0081] It can be understood that when the running state is traffic overload, it means that there is too much traffic on the peerlink, and the standby link of the peerlink can be enabled to share the traffic pressure of the peerlink, and part of the target traffic is redirected to the standby link. For reference, see Figure 2 , assuming that there is congestion in the peer link between switch A and switch B, after detecting the link congestion, part of the traffic can be redirected to other standby links (for example, through another physical link or standby port).

[0082] Step S303: When the running state is a link failure, isolate the peer link of the multi-link aggregation group protocol and redirect the target traffic to the standby link.

[0083] It can be understood that if a link failure occurs, the link needs to be isolated to prevent interference to other traffic. See Figure 2 , if a peer link detects a fault, the health status of the link will be identified through a heartbeat mechanism. Once a fault occurs, the fault recovery function will be immediately started, and the traffic will be guided to the standby link (for example, the second peer standby link from switch A to switch B).

[0084] In a feasible manner, after isolating the multi-link aggregation group protocol peer link and redirecting the target traffic to the standby link when the operating state is a link failure, the following steps are further included:

[0085] Monitor the link failure condition of the multi-link aggregation group protocol peer link;

[0086] When it is detected that the link failure is recovered, readjust the traffic routing of the multi-link aggregation group protocol peer link.

[0087] It is understandable that after the failed link is recovered, the traffic routing will be readjusted to ensure balanced load on the link. Refer to Figure 2 , the normal traffic transmission is from Host 1 to Switch A to the peer link to Switch B to Host 2. After detecting the peer link failure, the traffic between Switch A and Switch B automatically switches to the standby link. When the peer link is recovered, the traffic is redistributed back to the original link. And a success confirmation or failure feedback message will be sent to the M-LAG module so that the M-LAG module can update the internal configuration synchronization status and take corresponding subsequent measures.

[0088] In a feasible manner, after the step of monitoring the operating state of the multi-link aggregation group protocol peer link, the following steps are further included:

[0089] Generate an operating log of the multi-link aggregation group protocol peer link according to the operating state;

[0090] When the operating state is traffic overload or link failure, generate an alarm message according to the operating log.

[0091] It is understandable that by generating the operating log, the historical operating conditions of the link can be recorded for subsequent traceability, and an alarm message can be generated according to the operating log when the operating state is traffic overload or link failure for timely handling.

[0092] This embodiment monitors the operating state of the multi-link aggregation group protocol peer link; when the operating state is traffic overload, redirect part of the target traffic to the standby link; when the operating state is a link failure, isolate the multi-link aggregation group protocol peer link and redirect the target traffic to the standby link.

[0093] In summary, this embodiment improves the performance of the multi-link aggregation group protocol peer link by monitoring the operating state of the peer link and performing corresponding processing according to the change of the operating state.

[0094] This application further provides a traffic optimization device for the multi-link aggregation group protocol peer link. Please refer to Figure 4, the traffic optimization device for the multi-link aggregation group protocol peer link includes:

[0097] An allocation module 30, configured to obtain the network load in real time, and determine a bandwidth allocation policy according to the network load and the priority, so as to complete traffic optimization.

[0098] In this embodiment, the target traffic entering the multi-link aggregation group protocol peer link is detected; the traffic type and traffic direction of the target traffic are obtained, and the priority of the target traffic is determined according to the traffic type and the traffic direction; the network load is obtained in real time, and a bandwidth allocation policy is determined according to the network load and the priority, so as to complete traffic optimization.

[0099] In summary, in this embodiment, bandwidth allocation is performed through the network load and the priority of the traffic in the peer link, improving the performance of the multi-link aggregation group protocol peer link.

[0100] In one embodiment, the determination module 20 is further configured to determine whether the target traffic is data traffic according to the traffic type; determine whether the target traffic is in a preset direction according to the traffic direction; and determine the target traffic with the traffic type being data traffic and the traffic direction being the preset direction as high priority.

[0102] In one embodiment, the allocation module 30 is further configured to obtain the bandwidth utilization rate of the multi-link aggregation group protocol peer link in real time; when the bandwidth utilization rate reaches a preset threshold, adjust the bandwidth allocation policy to avoid overloading the peer link.

[0103] In one embodiment, the allocation module 30 is further configured to monitor the operating state of the multi-link aggregation group protocol peer link; when the operating state is traffic overload, redirect some of the target traffic to a standby link; when the operating state is a link failure, isolate the multi-link aggregation group protocol peer link and redirect the target traffic to a standby link.

[0104] In one embodiment, the allocation module 30 is further configured to monitor the link failure condition of the multi-link aggregation group protocol peer link; when it is detected that the link failure is restored, the traffic routing of the multi-link aggregation group protocol peer link is readjusted.
