[0052] The purpose, features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0053] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0054] 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.

[0055] The main solution of this application is to obtain the local first port status when the preset conditions are met; send the first port status to the master device of the cross-device link aggregation group; receive the link aggregation port status information from the master device of the cross-device link aggregation group; update the media access control address table according to the link aggregation port status information to obtain the target media access control address table; and forward data according to the target media access control address table.

[0056] In the currently used MLAG technology, there is a delay in state synchronization between MLAG devices when the link status changes, which affects stability. Therefore, how to reduce the synchronization delay of port states in cross-device link aggregation group technology and improve fault recovery efficiency is a problem that still needs to be solved.

[0057] The present application obtains the link aggregation port status based on the received link aggregation port status information and updates the media access control address table, thereby ensuring the availability of the media access control address table, enabling the cross-device link aggregation group to successfully complete data forwarding, reducing the synchronization delay of the port status in the cross-device link aggregation group technology, and improving the fault recovery efficiency.

[0058] Based on this, the embodiment of the present application provides a multi-link aggregation port state synchronization method based on a cross-device link aggregation group protocol, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol of this application.

[0059] In this embodiment, the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol includes steps S10 to S50:

[0060] Step S10: When a preset condition is met, obtaining the local first port status;

[0061] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a master device of an inter-device link aggregation group, a backup device of an inter-device link aggregation group, etc. The following describes this embodiment using a backup device of an inter-device link aggregation group as an example.

[0062] It's important to note that the first port refers to an MLAG port. An MLAG port refers to a physical or logical port that participates in multi-chassis link aggregation. In an MLAG configuration, multiple ports on a device (such as a switch) are aggregated into a single logical port, known as an MLAG port. Through MLAG technology, these ports can work together to achieve higher bandwidth and improved redundancy.

[0063] It is understandable that obtaining the local first port status may be triggered by various conditions, for example, obtaining the status of the first port immediately upon detecting a change in the port status, or obtaining the status of the first port at regular intervals.

[0064] In a feasible embodiment, when a preset condition is met, the step of obtaining the local first port status includes:

[0065] Monitor local port status;

[0066] When the local port state changes, the first port state is obtained according to the changed port state.

[0067] It is understandable that by monitoring the local port status, it is possible to promptly detect changes in the port and obtain the port status after the change. For example, if the port changes from open (up) to closed (down), the port status can be obtained as down; if the port changes from down to up, the port status can be obtained as up.

[0068] In a feasible embodiment, when a preset condition is met, the step of obtaining the local first port status includes:

[0069] Get the preset heartbeat interval;

[0070] According to the preset heartbeat interval, the local port status is acquired regularly to obtain the first port status.

[0071] It is understandable that the heartbeat mechanism can be used to periodically send the mlag port status to the master device. First, obtain the preset heartbeat interval. The heartbeat interval can be configured according to network conditions and requirements, usually between a few seconds and tens of seconds. Figure 2 , Figure 2 Configure the schematic for the mlag page. Figure 2 In [1], you can enable the mLAG function and set the mLAG system group ID. The two mLAG devices must be in the same ID group. The master device can be selected based on the system priority function. If the priority is the same, the master device is selected based on the MAC address. The heartbeat interval function can be used to set the time for sending heartbeat messages. The peer-link interface is the mLAG protocol message transmission path. Multiple mLAG ports can be configured through the mLAG interface function.

[0072] Step S20: sending the first port status to the master device of the inter-device link aggregation group;

[0073] It is understandable that after the first port status is acquired, the first port status may be sent to the master device of the inter-device link aggregation group so that the master device of the inter-device link aggregation group can calculate the multi-link aggregation port status.

[0074] In a feasible manner, after sending the first port status to the master device of the inter-device link aggregation group, the method further includes:

[0075] Send a confirmation request to the master device of the cross-device link aggregation group;

[0076] A confirmation signal from a master device of the inter-device link aggregation group is received to ensure that the first port state is successfully received.

[0077] It is understandable that after sending the first port status to the cross-device link aggregation group master device, there may be a situation where the information fails to be sent. Therefore, a confirmation request can be sent to the cross-device link aggregation group master device again, and a confirmation signal from the cross-device link aggregation group master device can be received to ensure that the first port status is successfully sent to the cross-device link aggregation group master device.

[0078] Step S30: receiving link aggregation port status information from the master device of the cross-device link aggregation group;

[0079] It is understandable that after sending the first port status to the cross-device link aggregation group master device, the cross-device link aggregation group master device can calculate the link aggregation port status information and reply, and receive the link aggregation port status information from the cross-device link aggregation group master device.

[0080] Step S40: updating the media access control address table according to the link aggregation port state information to obtain a target media access control address table;

[0081] As you can understand, the Media Access Control (MAC) address table records the mapping between the MAC addresses of other devices and interfaces, as well as interface-related information. This is the foundation for network devices to implement data forwarding. When a switch receives a data packet, it queries the MAC table based on the packet's destination MAC address to determine how to forward the packet. In this embodiment, the MAC address table is updated based on the link aggregation port status information to obtain the target MAC address table, ensuring smooth data transmission.

[0082] In a feasible manner, the step of updating the media access control address table according to the link aggregation port state information to obtain the target media access control address table includes:

[0083] When the link aggregation port state information is in an open state, adding the target media access control address to the media access control address table to obtain a target media access control address table;

[0084] When the link aggregation port state information is in a closed state, the target media access control address is deleted from the media access control address table to obtain a target media access control address table.

[0085] It is understandable that the addition or deletion of the media access control address table may be determined according to the link aggregation port status information.

[0086] Step S50: forwarding data according to the target media access control address table.

[0087] It is understandable that available MAC addresses are added to the target media access control address table or unavailable MAC addresses are deleted, and data can be forwarded according to the target media access control address table to avoid forwarding failures.

[0088] In this embodiment, when a preset condition is met, the local first port status is obtained; the first port status is sent to the master device of the cross-device link aggregation group; the link aggregation port status information is received from the master device of the cross-device link aggregation group; the media access control address table is updated according to the link aggregation port status information to obtain the target media access control address table; and data is forwarded according to the target media access control address table.

[0089] To sum up, this embodiment obtains the link aggregation port status based on the received link aggregation port status information and updates the media access control address table, thereby ensuring the availability of the media access control address table, enabling the cross-device link aggregation group to successfully complete data forwarding, reducing the synchronization delay of the port status in the cross-device link aggregation group technology, and improving the fault recovery efficiency.

[0090] 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 embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 3 , Figure 3 This is a flow chart of the second embodiment of the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol of this application.

[0091] In this embodiment, the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol includes steps S100 to S400:

[0092] Step S100: receiving first port status information from a standby device in an inter-device link aggregation group;

[0093] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, a master device of an inter-device link aggregation group, a backup device of an inter-device link aggregation group, etc. The following describes this embodiment using the master device of an inter-device link aggregation group as an example.

[0094] It is understandable that the first port status information of the cross-device link aggregation group standby device records the survival status of the port. Through the first port status information, it can be known whether the port of the cross-device link aggregation group standby device is enabled.

[0095] In a feasible manner, after receiving the first port status information from the inter-device link aggregation group backup device, the method further includes:

[0096] Receive a confirmation request from a standby device in a cross-device link aggregation group;

[0097] And send a confirmation signal to the inter-device link aggregation group backup device according to the confirmation request.

[0098] It is understandable that in order to ensure successful information transmission, the cross-device link aggregation group backup device may make a confirmation request. Therefore, after receiving the confirmation request from the cross-device link aggregation group backup device, a confirmation signal may be sent to the cross-device link aggregation group backup device according to the confirmation request.

[0099] Step S200: Obtain local second port information;

[0100] It is understandable that the calculation of the multi-link aggregation port state information also requires the local port state, and therefore, the local second port information may be obtained to calculate the final multi-link aggregation port state information.

[0101] Step S300: Obtaining multi-link aggregation port status information according to the first port status information and the second port status information;

[0102] It is understandable that for a cross-device link aggregation group, the MLAG port is considered down only when both devices' MLAG ports are down. If the MLAG port of the other device is up and the MLAG port of the local device is down, the local device will consider its MLAG port to be up. In this case, the status of the MLAG ports needs to be quickly synchronized. Figure 4 , Figure 4 This is a schematic diagram of determining the status of a multi-link aggregation port. Figure 4 The master device is the master device of the cross-device link aggregation group, the backup device is the backup device of the cross-device link aggregation group, the mlag port is the port, and the aggregation device is the other device connected to the ports of the master device and the backup device of the cross-device link aggregation group.

[0103] In a feasible manner, the step of obtaining the multi-link aggregation port state information according to the first port state information and the second port state information includes:

[0104] When the first port status information and the second port status information are both in a closed state, the multi-link aggregation port status information is obtained as a closed state;

[0105] When at least one of the first port status information and the second port status information is in an open state, the multi-link aggregation port status information is obtained as being in an open state.

[0106] Step S400: Synchronize the link aggregation port status information to the cross-device link aggregation group backup device.

[0107] It is understandable that after calculating the link aggregation port state information, synchronizing the link aggregation port state information to the cross-device link aggregation group backup device can enable the cross-device link aggregation group backup device to complete the MAC table update and ensure data forwarding.

[0108] For example, in order to help understand the implementation process of the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol obtained by combining this embodiment with the above embodiment 1, please refer to Figure 5 , Figure 5 A simplified flowchart of a multi-link aggregation port state synchronization method based on a cross-device link aggregation group protocol is provided. Specifically, when the mlag port of a backup device changes or a timed time interval is reached, the backup device sends an mlag message to the master device. The master device receives the mlag message from the backup device, then calculates the state of the protocol mlag port and sends the state of the protocol mlag port to the backup device.

[0109] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the multi-link aggregation port state synchronization method based on the cross-device link aggregation group protocol of the present application. More forms of simple transformations based on this technical concept are all within the scope of protection of the present application.

[0113] A receiving module 30 is configured to receive link aggregation port status information from a master device of an inter-device link aggregation group;

[0114] An updating module 40 is configured to update a media access control address table according to the link aggregation port state information to obtain a target media access control address table;

[0115] The forwarding module 50 is configured to forward data according to the target media access control address table.

[0116] In this embodiment, when a preset condition is met, the local first port status is obtained; the first port status is sent to the master device of the cross-device link aggregation group; the link aggregation port status information is received from the master device of the cross-device link aggregation group; the media access control address table is updated according to the link aggregation port status information to obtain the target media access control address table; and data is forwarded according to the target media access control address table.

[0117] To sum up, this embodiment obtains the link aggregation port status based on the received link aggregation port status information and updates the media access control address table, thereby ensuring the availability of the media access control address table, enabling the cross-device link aggregation group to successfully complete data forwarding, reducing the synchronization delay of the port status in the cross-device link aggregation group technology, and improving the fault recovery efficiency.
