[0002] With the popularity of data centers and large-scale networks, Multi-Chassis Link Aggregation Group (MLAG) technology has become a common solution to improve network redundancy and reliability. Through the MLAG protocol, redundancy and load balancing of links between multiple switches can be achieved, which enhances the stability of the network without reducing network performance. However, the existing MLAG technology has some defects in some network topologies, especially in the processing of peer link isolation direction. At present, the MLAG protocol is mainly used for synchronization status and load balancing in the peer link connection between multiple switches, but the processing of the peer link isolation direction lacks flexibility, which affects the normal operation of the network. In addition, the existing MLAG implementation usually ignores the isolation requirements of different network traffic, resulting in redundant traffic and performance conflicts when the data flow passes through the peer link. In some application scenarios, the failure or performance bottleneck of the peer link will cause the performance of the entire MLAG link to degrade. Therefore, how to improve the performance of the multi-link aggregation group protocol peer link is a problem that still needs to be solved.

[0022] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0023] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The main solution of the present application is to detect the target traffic entering the multi-link aggregation group protocol peer link; 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 strategy according to the network load and the priority to complete traffic optimization.

[0025] At present, the MLAG protocol is mainly used for synchronization and load balancing of Peerlink connections between multiple switches, but the isolation direction of Peerlink lacks flexibility, 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, Peerlink failures or performance bottlenecks will cause the performance of the entire MLAG link to degrade. Therefore, how to improve the performance of the multi-link aggregation group protocol peer link is a problem that still needs to be solved.

[0026] The present application allocates bandwidth by comparing network load with the priority of traffic in peer links, thereby improving the performance of multi-link aggregation group protocol peer links.

[0027] Based on this, the embodiment of the present application provides a method for optimizing the traffic of a multi-link aggregation group protocol peer link, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for traffic optimization of peer links of a multi-link aggregation group protocol of the present application.

[0028] In this embodiment, the traffic optimization method of the multi-link aggregation group protocol peer link includes steps S10 to S30: Step S10: Detecting target traffic entering the multi-link aggregation group protocol peer link; 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 capable of realizing the above functions, a traffic optimization device for a multi-link aggregation group protocol peer link, etc. The following takes a traffic optimization device for a multi-link aggregation group protocol peer link as an example to illustrate this embodiment and the following embodiments.

[0029] It should be noted that multi-link aggregation group, or MLAG, is a network technology that is mainly used to improve network reliability and bandwidth. It allows two or more network devices (such as switches or routers) to form a logical aggregate link through multiple physical links, thereby providing higher throughput and redundancy. Peerlink is a key link in the MLAG configuration, used to connect two MLAG peer switches (or other network devices). It is a direct link that must be aggregated, 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.

[0030] Step S20: Obtaining the traffic type and traffic direction of the target traffic, and determining the priority of the target traffic according to the traffic type and the traffic direction; It is understandable that there are different types of traffic through the multi-link aggregation group protocol peer link, such as data traffic, control traffic, etc. In different scenarios, different types of traffic have different priorities, and the priority can be determined based on the traffic type; in addition, the traffic on the multi-link aggregation group protocol peer link can also be classified by traffic direction, and the priority can be determined together 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 be given priority treatment based on the traffic type. For reference Figure 2 , Figure 2 The figure is a schematic diagram of the network topology of the multi-link aggregation group protocol peer link. Figure 2 In the example, the heartbeat link is used 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 data traffic, it is determined to flow through the peer link from switch A to switch B. The data traffic is marked as high priority to ensure that the data can pass through the idle link first.

[0031] In a feasible manner, the step of determining the priority of the target traffic according to the traffic type and the traffic direction includes: Determining whether the target traffic is data traffic according to the traffic type; Determining whether the target flow is in a preset direction according to the flow direction; The target traffic whose traffic type is data traffic and whose traffic direction is a preset direction is determined as a high priority.

[0032] It is understandable that in different scenarios, the priority determination criteria are different. For example, the target traffic whose traffic type is data traffic and whose traffic direction is a preset direction can be determined as a high priority, while other traffic can be determined as a low priority.

[0033] Step S30: Acquire the network load in real time, and determine the bandwidth allocation strategy according to the network load and the priority to achieve traffic optimization.

[0034] It is understandable that after obtaining the network load and priority, a bandwidth allocation strategy can be formulated based on the network load and the priority to ensure that high-priority traffic can be processed first. The bandwidth allocation of the Peerlink link is adjusted according to the real-time network load. Bandwidth is allocated to different traffic to ensure that the network bandwidth is not overloaded and that traffic can be transmitted according to priority.

[0035] In a feasible manner, the step of determining the bandwidth allocation strategy according to the network load and the priority includes: Obtaining network congestion information of a peer link according to the network load; Determining the bandwidth requirement of the target traffic according to the priority; A bandwidth allocation strategy for the target traffic is determined according to the network congestion information and the bandwidth demand.

[0036] It is understandable that, based on the network congestion information, the traffic situation of the peerlink link can be obtained, and bandwidth allocation can be performed in combination with the bandwidth demand of the target traffic, so that the peerlink link can be fully utilized to complete traffic optimization.

[0037] In a feasible manner, after determining the bandwidth allocation strategy of the target traffic according to the network congestion information and the bandwidth demand, the method further includes: Obtain the bandwidth usage of multi-link aggregation group protocol peer links in real time; When the bandwidth usage reaches a preset threshold, the bandwidth allocation strategy is adjusted to avoid overloading of the peer link.

[0038] It is understandable that in the process of traffic passing through the Peerlink link, the bandwidth usage is monitored in real time. If it is found that the bandwidth usage of a link is too high, the bandwidth allocation strategy can be dynamically adjusted to ensure reasonable traffic allocation and avoid link overload.

[0039] This embodiment detects target traffic entering a multi-link aggregation group protocol peer link; obtains the traffic type and traffic direction of the target traffic, and determines the priority of the target traffic based on the traffic type and the traffic direction; obtains the network load in real time, and determines a bandwidth allocation strategy based on the network load and the priority to complete traffic optimization.

[0040] In summary, this embodiment allocates bandwidth according to the network load and the priority of the traffic in the peer link, thereby improving the performance of the multi-link aggregation group protocol peer link.

[0041] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 After step S30, the traffic optimization method of the multi-link aggregation group protocol peer link further includes steps S301 to S303: Step S301: monitoring the operating status of the multi-link aggregation group protocol peer link; It is understandable that by monitoring the running status of the multi-link aggregation group protocol peer link, the traffic changes in the peer link can be obtained in time, so as to perform fault processing in time.

[0042] Step S302: when the operation state is traffic overload, redirecting part of the target traffic to a standby link; It is understandable that when the operating state is traffic overload, it means that the traffic of peerlink is too much, and the peerlink backup link can be enabled to share the traffic pressure of peerlink and redirect part of the target traffic to the backup link. Figure 2 ,Assume that congestion occurs on the peer link between switch A and switch B, after detecting the link congestion, part of the traffic can be redirected to other backup links (e.g., through another physical link or backup port).

[0043] Step S303: When the operating state is a link failure, the LAPG peer link is isolated and the target traffic is redirected to a standby link.

[0044] It is understandable that if a link failure occurs, the link needs to be isolated to prevent interference with other traffic. Figure 2 If a peer link detects a failure, the heartbeat mechanism will be used to identify the health of the link. Once a failure occurs, the fault recovery function will be immediately activated and the traffic will be directed to the backup link (for example, the second peer backup link from switch A to switch B).

[0045] In a feasible manner, when the operating state is a link failure, the multi-link aggregation group protocol peer link is isolated, and the target traffic is redirected to the standby link, further comprising: Monitor link failures of multi-link aggregation group protocol peer links; When link failure recovery is detected, the traffic routing of the multi-link aggregation group protocol peer link is readjusted.

[0046] It is understandable that when the failed link is restored, the traffic routing will be readjusted to ensure balanced load on the link. Figure 2 , the normal traffic transmission is from host 1 to switch A to peer link to switch B to host 2. After detecting the peer link failure, the traffic of switch A and switch B is automatically switched to the backup link. When the peer link is restored, the traffic is redistributed back to the original link. 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 follow-up measures.

[0047] In a feasible manner, after the step of monitoring the running status of the multi-link aggregation group protocol peer link, the method further includes: Generate an operation log of the multi-link aggregation group protocol peer link according to the operation status; When the operation status is traffic overload or link failure, alarm information is generated according to the operation log.

[0048] It is understandable that by generating an operation log, the historical operation status of the link can be recorded for subsequent backtracking, and alarm information can be generated based on the operation log when the operation status is traffic overload or link failure for timely processing.

[0049] This embodiment monitors the operating status of the multi-link aggregation group protocol peer link; when the operating status is traffic overload, part of the target traffic is redirected to the backup link; when the operating status is link failure, the multi-link aggregation group protocol peer link is isolated and the target traffic is redirected to the backup link.

[0050] In summary, this embodiment improves the performance of the multi-link aggregation group protocol peer link by monitoring the running status of the peer link and performing corresponding processing according to the change of the running status.

[0051] The present application also provides a traffic optimization device for a multi-link aggregation group protocol peer link, please refer to Figure 4 , the traffic optimization device of the multi-link aggregation group protocol peer link includes: A detection module 10, configured to detect target traffic entering a multi-link aggregation group protocol peer link; A determination module 20, configured to obtain a traffic type and a traffic direction of the target traffic, and determine a priority of the target traffic according to the traffic type and the traffic direction; The allocation module 30 is used to obtain the network load in real time and determine the bandwidth allocation strategy according to the network load and the priority to achieve traffic optimization.

[0052] This embodiment detects target traffic entering a multi-link aggregation group protocol peer link; obtains the traffic type and traffic direction of the target traffic, and determines the priority of the target traffic based on the traffic type and the traffic direction; obtains the network load in real time, and determines a bandwidth allocation strategy based on the network load and the priority to complete traffic optimization.

[0053] In summary, this embodiment allocates bandwidth according to the network load and the priority of the traffic in the peer link, thereby improving the performance of the multi-link aggregation group protocol peer link.

[0054] In one embodiment, the determination module 20 is also used to determine whether the target traffic is data traffic based on the traffic type; determine whether the target traffic is a preset direction based on the traffic direction; and determine the target traffic whose traffic type is data traffic and whose traffic direction is a preset direction as a high priority.

[0055] In one embodiment, the allocation module 30 is further used to obtain network congestion information of the peer link according to the network load; determine the bandwidth requirement of the target traffic according to the priority; and determine the bandwidth allocation strategy of the target traffic according to the network congestion information and the bandwidth requirement.

[0056] In one embodiment, the allocation module 30 is further used to obtain bandwidth usage of the MLAG peer link in real time; when the bandwidth usage reaches a preset threshold, the bandwidth allocation strategy is adjusted to avoid peer link overload.

[0057] In one embodiment, the allocation module 30 is also used to monitor the operating status of the multi-link aggregation group protocol peer link; when the operating status is traffic overload, part of the target traffic is redirected to the backup link; when the operating status is link failure, the multi-link aggregation group protocol peer link is isolated and the target traffic is redirected to the backup link.

[0058] In one embodiment, the allocation module 30 is further configured to monitor link failures of the LAPG peer links; and when link failure recovery is detected, readjust the traffic routing of the LAPG peer links.
