[0002] In the application scenario of the switch MLAG (Multiple Link Aggregation Group) protocol, the synchronization of MAC and ARP information is a key factor in ensuring network performance and reliability.

[0003] However, in actual deployment, existing solutions still have shortcomings. When multiple switches share a link aggregation group, if their MAC address tables are not synchronized, or if the ARP cache information is inconsistent between different switches, network traffic may be routed incorrectly, thus affecting overall network performance. Therefore, in an environment that requires high stability and load balancing, how to ensure that this information remains consistent between multiple switches has become a technical challenge.

[0017] When the detection result is that the original physical address information is different from the physical address information in the heartbeat signal, or the original address resolution protocol information is different from the address resolution protocol information in the heartbeat signal, a synchronization mechanism is triggered;

[0018] A synchronization request instruction is sent to the switch whose position is recorded in the detection report, so that the switch receiving the synchronization request instruction updates the physical address information or the address resolution protocol information according to the heartbeat signal, and after the information synchronization is completed, the switch sends a confirmation signal to confirm that the information has been successfully synchronized.

[0019] In one embodiment, the step of receiving the confirmation signal and completing information synchronization includes:

[0021] After the detection information synchronization is completed, the latest physical address information and address resolution protocol information are updated to restore the normal operation of the network;

[0022] A result report is generated, which records the process and results of the information synchronization.

[0023] In one embodiment, the step of detecting whether information synchronization has been completed after receiving the confirmation signal further includes:

[0024] When it is detected that the updated physical address information or the updated address resolution protocol information of the switch is different from the heartbeat signal, the fault recovery mechanism is triggered to work through the preset backup path and automatic switching function.

[0045] 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.

[0046] 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.

[0047] The main solution of the embodiment of the present application is: by obtaining the original physical address information and the original address resolution protocol information, obtaining the heartbeat signal, checking the consistency of the original physical address information and the original address resolution protocol information with the heartbeat signal, and obtaining the detection result; when the detection result is that the original physical address information is different from the heartbeat signal or the original address resolution protocol information is different from the heartbeat signal, triggering the synchronization mechanism, sending a synchronization request instruction to the switch, so that the switch synchronizes the information and feeds back a confirmation signal, receiving the confirmation signal, and completing the information synchronization.

[0048] Based on this, the embodiment of the present application provides a switch information synchronization method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the switch information synchronization method of the present application.

[0049] In this embodiment, the switch information synchronization method includes steps S10 to S50:

[0050] Step S10, obtaining original physical address information and original address resolution protocol information.

[0051] It should be noted that in the switch MLAG protocol, each switch records the MAC addresses it observes and their corresponding port information to form a MAC address table, that is, physical address information. Similarly, the original address resolution protocol information contains the mapping of IP addresses to MAC addresses, which is essential for implementing IP-based packet forwarding. In order to maintain the consistency of the entire MLAG system, snapshots of this information, the so-called original data, must be obtained regularly.

[0052] The operation of obtaining this raw data can be achieved through the software API or command line interface (CLI), depending on the switch's operating system. For example, an administrator or automated script can execute commands to export current MAC address information and ARP cache information, such as show mac-address-table and show arp. After executing these commands, the switch will return all currently stored MAC address entries and their corresponding port information, as well as all known ARP entries.

[0053] Step S20, obtaining a heartbeat signal, where the heartbeat signal includes updated physical address information of the switch and updated address resolution protocol information of the switch.

[0054] It should be noted that in the switch MLAG protocol, a mechanism called "heartbeat" is used to ensure the consistency of MAC address information and ARP cache information between switches. This mechanism allows switches to periodically send heartbeat signals, which contain updated physical address information and address resolution protocol information. The heartbeat signal is not only used to detect whether a connection exists, but more importantly, it is used to synchronize network status information between switches to ensure network stability and efficiency.

[0055] When a heartbeat signal is received, the latest MAC address information and ARP cache information contained therein are compared with the information stored in the heartbeat signal. If any differences are found, such as new MAC address entries, removed entries, or changed entries, the MAC address table and ARP cache are updated according to the received heartbeat signal. The purpose of this is to ensure that all switches participating in MLAG have the same information and avoid problems caused by inconsistent information, such as data packets being incorrectly routed or causing network performance degradation.

[0056] In addition, the heartbeat signal can also contain confirmation information, indicating that the previously sent update has been successfully received and applied. If the sender does not receive the confirmation information, it can resend the heartbeat signal until the confirmation information is received.

[0057] Step S30, performing consistency check on the original physical address information, the original address resolution protocol information and the heartbeat signal to obtain a detection result.

[0058] It is important to understand that during this process, each switch will periodically receive heartbeat signals from other switches, which contain the latest MAC address table and ARP cache information. When receiving the heartbeat signal, the switch will compare its own MAC address table and ARP cache with the received information to detect whether there is a difference between the two.

[0059] Specifically, consistency checking involves understanding whether the MAC address table and ARP cache entries stored by the local switch exactly match the information reported by the remote switch. For example, if the local switch's MAC address table is missing a newly added entry, or has an entry that no longer exists, it will be marked as inconsistent. Similarly, for the ARP cache, any new entries that do not exist locally, or entries that are still retained locally but have actually been removed, will also be considered inconsistent. To achieve this, the switch analyzes each update in the heartbeat signal, including new, deleted, and modified MAC address entries and ARP cache entries. If an inconsistency is detected, the switch will record the specific inconsistency and prepare to trigger a synchronization mechanism to update its own MAC address table and ARP cache to make them consistent with the information in the heartbeat signal.

[0060] Step S40, when the detection result is that the original physical address information is different from the heartbeat signal or the original address resolution protocol information is different from the heartbeat signal, the synchronization mechanism is triggered to send a synchronization request instruction to the switch, so that the switch synchronizes the information and feeds back a confirmation signal.

[0061] It should be noted that when the detection results show that the original physical address information or the original address resolution protocol information is inconsistent with the information in the received heartbeat signal, the system will immediately start the synchronization mechanism. This mechanism is designed to quickly correct the information differences between switches to ensure that the MAC address table and ARP cache information within the entire MLAG system are consistent.

[0062] Specifically, the switch that first detects the inconsistency will generate a synchronization request instruction. This instruction contains specific information that needs to be synchronized, such as which MAC address entries need to be added, deleted, or updated, and which ARP cache entries need to be synchronized. Subsequently, the instruction is sent to other switches participating in MLAG. After receiving the synchronization request instruction, the receiving switch will update its local MAC address table and ARP cache according to the instruction content. After the update is complete, the receiving switch will send a confirmation signal to the switch that sent the synchronization request, indicating that the information has been synchronized. This confirmation signal is very important to prevent duplicate synchronization, and it also serves as a sign of the success of the synchronization process.

[0063] Step S50, receiving a confirmation signal and completing information synchronization.

[0064] It should be noted that after completing the synchronization of the MAC address table and ARP cache information, the switch will receive confirmation signals from other switches. These confirmation signals indicate that the information synchronization has been successfully performed and all related switches now have the same and latest MAC address table and ARP cache information.

[0065] Further, when the switch receives the confirmation signal, it updates its internal status information to indicate that the synchronization has been completed. This step is critical to ensure that all switches are in the same state. Only when all switches confirm the results of the synchronization can the information in the entire system be considered consistent. In addition, the confirmation signal also helps to establish a reliable communication channel to ensure the integrity of information transmission in a complex network environment. Once all confirmation signals are received, the information synchronization is officially completed. At this point, it is determined that all switches participating in the MLAG protocol have the same MAC address table and ARP cache information, which helps prevent incorrect routing of data packets or other network problems caused by information asynchrony. This process not only enhances the stability of the network, but also improves the performance of the network, because all switches can correctly process and forward data traffic, reducing unnecessary delays and errors.

[0066] This embodiment provides a switch information synchronization method, which obtains the original physical address information and the original address resolution protocol information, obtains the heartbeat signal, performs consistency check on the original physical address information and the original address resolution protocol information and the heartbeat signal, and obtains the detection result. When the detection result is that the original physical address information is different from the heartbeat signal or the original address resolution protocol information is different from the heartbeat signal, the synchronization mechanism is triggered, and a synchronization request instruction is sent to the switch to enable the switch to synchronize the information and feedback a confirmation signal, and the confirmation signal is received to complete the information synchronization. The MAC and ARP information are regularly checked and synchronized through the heartbeat signal, and the synchronization request is automatically triggered to ensure information consistency and improve network stability and reliability.

[0067] 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 refer to the above introduction, and will not be repeated later. Figure 2 The switch information synchronization method step S30 further includes steps S301 to S302:

[0068] Step S301, obtaining a consistency check time interval, wherein the time interval is configured according to the network conditions and requirements of each switch.

[0069] It should be noted that the consistency check interval refers to the frequency at which the switch performs consistency checks on the MAC address table and ARP cache information. This parameter can be flexibly configured according to the actual conditions and specific requirements of the network in which each switch is located. The choice of the time interval has an important impact on network performance because it directly determines the speed and accuracy of information synchronization between network devices.

[0070] When configuring the interval for consistency checks, network administrators need to consider several key factors. The first is the characteristics of network traffic. If the network traffic is very dense and changes frequently, a shorter check interval may be required to ensure the consistency of information. On the other hand, if the network is relatively static and the traffic does not change much, the check interval can be appropriately extended to reduce resource consumption. The second is the network scale and topology. For large networks or environments with complex topologies, more frequent consistency checks may be necessary to cope with various possible failures. For smaller network environments, the check interval can be adjusted according to actual conditions. In addition, the performance of network devices is also a consideration. Under high load conditions, frequent consistency checks may increase the burden on the switch.

[0071] Therefore, when configuring the time interval, the processing power of the switch and the system resource status should be considered to balance the frequency of consistency checks and the workload of the device. Finally, network administrators also need to consider business needs and service level agreements (SLAs) to ensure that the frequency of consistency checks meets the requirements of business continuity and service quality.

[0072] Step S302: Compare the original physical address information and the original address resolution protocol information with the updated physical address information of the switch and the updated address resolution protocol information of the switch in the heartbeat signal according to the time interval to obtain a detection result.

[0073] It should be noted that during this process, each switch will compare its original physical address information and ARP cache information with the updated information contained in the received heartbeat signal. The purpose of this process is to detect whether there are any inconsistencies. Specifically, the switch will check whether its local MAC address table entries are consistent with the MAC address information in the received heartbeat signal, including checking whether there are new, deleted or modified entries. Similarly, the switch will check whether its ARP cache information matches the information in the heartbeat signal. If any inconsistencies are found, such as missing entries in the local MAC address table or ARP cache or entries that should not exist, the switch will record these differences.

[0074] Further, step S302 also includes: when the detection result is that the original physical address information is different from the heartbeat signal or the original address resolution protocol information is different from the heartbeat signal, a detection report is generated, wherein the detection report records the location of the switch with inconsistent information. When it is detected that the original physical address information or ARP cache information is inconsistent with the information in the received heartbeat signal, the switch will generate a detailed detection report. This report will record the location of all switches with inconsistent information and other relevant information. This can help network administrators quickly locate the problem, understand which switches need to be synchronized and updated, and take appropriate measures to solve the problem.

[0075] Further, after step S302, it also includes: when the detection result is that the original physical address information is different from the MAC address information in the heartbeat signal, or the original address resolution protocol information is different from the ARP cache information in the heartbeat signal, triggering the synchronization mechanism. Sending a synchronization request instruction to the switch whose position is recorded in the above detection report, so that the switch receiving the above synchronization request instruction updates the MAC address information or ARP cache information according to the heartbeat signal, and after the information synchronization is completed, the switch sends a confirmation signal to confirm that the information has been successfully synchronized. When the detection result shows that the original physical address information or ARP cache information is inconsistent with the information in the heartbeat signal, the system automatically triggers the synchronization mechanism. The purpose of this mechanism is to quickly correct the information differences between the switches and ensure that the MAC address table and ARP cache information in the entire MLAG system are consistent. First, the system will generate a detection report to record the location and related details of all switches where inconsistent information is detected. Then, based on this report, the system will send synchronization request instructions to the switches at these locations. These instructions contain specific information that needs to be synchronized, such as MAC address entries and ARP cache entries that need to be added, deleted or updated. The switch that receives the synchronization request instruction will update its local MAC address table and ARP cache information according to the instruction content. During the update process, the switch will adjust its local storage according to the latest information in the heartbeat signal to achieve consistency with the sender. After the update is completed, the switch will send a confirmation signal to the switch that initiated the synchronization request, indicating that the information has been synchronized.

[0076] This embodiment obtains the time interval of the consistency check, and compares the original physical address information and the original address resolution protocol information with the updated physical address information of the switch and the updated address resolution protocol information of the switch in the heartbeat signal according to the time interval to obtain the detection result. The MAC and ARP information are compared by the timed consistency check, and synchronization is triggered when they do not match, so as to ensure information consistency and improve network stability.

[0077] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 3 The switch information synchronization method step S50 further includes steps S501 to S503:

[0078] Step S501: After receiving the confirmation signal, check whether the information synchronization has been completed.

[0079] It should be noted that this step verifies that all necessary updates have been performed correctly and that all switches participating in the synchronization have applied the latest information. When confirmation signals are received, check whether these signals cover all items in the previously sent synchronization requests. If all requested updates are confirmed, then the information synchronization is considered complete. At this point, the system will update its internal state, marking the synchronization operation as completed, and may record the successful synchronization event for later auditing or troubleshooting.

[0080] Furthermore, step S501 also includes triggering the fault recovery mechanism to work through the preset backup path and automatic switching function when it is detected that the updated physical address information or the updated address resolution protocol information of the switch is inconsistent with the heartbeat signal. When it is detected that the updated physical address information or the address resolution protocol information is inconsistent with the information in the received heartbeat signal, the switch will immediately trigger the fault recovery mechanism. The design purpose of this mechanism is to quickly restore the normal operation of the network through pre-configured backup paths and automatic switching functions. Specifically, when inconsistency is detected, the system will automatically select a pre-configured backup path. The existence of the backup path is to provide an alternative communication line when the main network path fails, ensuring that the data flow can continue to be transmitted smoothly. At the same time, the system will automatically activate the switching function to immediately transfer the network traffic to the backup path, thereby avoiding network interruption caused by inconsistent information.

[0081] If not all acknowledgments are received within the expected time, or if the acknowledgments received indicate that some updates were not successfully applied, the switch will resend the synchronization request until all information is correctly synchronized. This ensures that information consistency is eventually achieved even in the event of poor network conditions or problems with some switches.

[0082] Step S502: After the detection information synchronization is completed, the latest physical address information and address resolution protocol information are updated to restore the normal operation of the network.

[0083] It should be noted that after receiving all necessary confirmation signals indicating that all relevant switches have successfully updated their MAC address tables and ARP caches, the system will apply this latest information to actual network traffic processing.

[0084] Specifically, the switch will replace the original MAC address table entries and ARP cache entries and use the latest information that has just been synchronized. This means that any newly received data packets will be processed according to the updated information, ensuring that the data packets can be correctly forwarded to the destination. In addition, by updating the latest information, packet loss or routing errors caused by inconsistent information can be avoided, thereby improving the stability and performance of the network.

[0085] Further, step S502 also includes: after detecting that the information synchronization is completed, updating the physical address information and the address resolution protocol information to the latest state. Then verify whether the network traffic is correctly routed according to the updated physical address information and the address resolution protocol information to obtain a verification result. In order to verify whether the network traffic is correctly routed as expected, the switch monitors the actual traffic behavior. This includes checking whether the data packet is correctly forwarded to the target device, and whether any abnormal situation occurs, such as packet loss or wrong routing. In this way, it can be confirmed whether the updated physical address information and the address resolution protocol information effectively improve the operation of the network. When the verification result is that the stable operation is correctly routed, the normal operation of the network is restored. If the verification result shows that the network traffic is indeed correctly routed according to the updated information, it can be confirmed that the information synchronization process is successful and the network has been restored to a normal operating state.

[0086] Step S503: Generate a result report, which records the process and results of information synchronization.

[0087] It should be noted that the generated result report will record the process and results of information synchronization in detail to ensure that network administrators can fully understand the synchronization operation. The result report will cover the status before synchronization, the synchronization process, the synchronization results, and the summary and suggestions. The status before synchronization is the status of the original physical address information and ARP cache information of each switch before the start, as well as the detected inconsistencies. The synchronization process is each step of the synchronization operation, including when the synchronization mechanism is started, which switches are sent synchronization request instructions, how the switches respond, and when they send back confirmation signals.

[0088] The synchronization result is that once all switches confirm that the information has been successfully synchronized, the report will record the final status, that is, the MAC address information and ARP cache information held by all switches have been updated to the latest status. Summary and suggestions are based on the above information. The report will summarize the success or failure of this synchronization operation and make suggestions for improvement. For example, if it is detected that some switches are responding slowly, the report may suggest checking the network conditions of these devices or optimizing certain parameters in the synchronization mechanism.

[0089] The report will also include results that verify that network traffic is being routed correctly based on the updated information, confirming that the synchronization has achieved the expected results. In addition, the report will also point out any anomalies, such as delayed responses or failed synchronization attempts.

[0090] This embodiment detects whether information synchronization has been completed after receiving a confirmation signal, and after detecting that information synchronization is completed, updates the latest physical address information and address resolution protocol information, restores the normal operation of the network, and generates a result report. After receiving a confirmation signal, the synchronization is detected to be completed, the MAC and ARP information is updated, the network operation is restored, and a result report is generated to ensure information consistency and network stability.
