The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Referring to fig. 1, a flow chart of a network device configuration synchronization method according to an exemplary embodiment of the present application is shown, where the method may be applied to a VSM member device in a VSM instance, and includes the following steps:
Step 101: when the equipment is the main member equipment in the VSM example, if a first state message from the standby member equipment in the VSM example is received, the state of the standby member equipment is marked as unconfigurable based on the first state message.
In this embodiment, when a network device joins a VSM instance, its role in the VSM instance may be determined by role election. After all member devices in the VSM instance determine their roles in the VSM instance, the primary member device in the VSM instance may issue the user initial configuration to all member devices, so that all member devices in the VSM instance store the same configuration.
In this step, when the network device determines that it is a standby member device in the VSM instance to which the network device belongs through role election and starts VSM initial configuration, the network device may send a first status message to a primary member device in the VSM instance. When receiving the first status message, the primary member device in the VSM instance may mark the status of the standby member device that sent the first status message as unconfigurable.
step 102: and if a second state message from the standby member equipment in the VSM example is received, marking the state of the standby member equipment as configurable based on the second state message.
In this embodiment, when the standby member device in the VSM instance completes the VSM initial configuration, the second status message may be sent to the primary member device in the VSM instance. When receiving the second status message, the primary member device in the VSM instance may mark the standby member device that sent the second status message as configurable.
step 103: and if receiving a configuration request from a management side, locally executing configuration modification based on the configuration request, and sending the configuration request to the standby member equipment with configurable state, so that the standby member equipment locally executes the same configuration modification based on the configuration request.
In this embodiment, when the primary member device in the VSM instance receives a configuration request from the management side, the configuration request may be sent to the standby member device whose state is configurable, in addition to locally performing configuration modification based on the configuration request. In one example, a primary member device in a VSM instance may locally maintain a standby member device state table, which may include the state of each standby member device in the VSM instance and its device identification, for example: and the main member device can determine the standby member device with the configurable state according to the table and send a configuration request from the management side to the standby member device.
After receiving the configuration request, the standby member device with the configurable state can locally execute the same configuration modification as the main member device so as to ensure the configuration synchronization with the main member device.
it is to be noted that, in the present application, the master member device and the standby member device may implement the first status packet and the second status packet by using an existing protocol, for example: the existing protocol can be extended, and the flag bit for identifying the first status packet and the second status packet is added in the protocol packet. Optionally, the state of the member device may also be carried in the protocol packet, for example: if the message is not configurable, the message may be determined to be a first status message, and if the message is configurable, the message may be determined to be a second status message, which is not particularly limited in this application.
As can be seen from the foregoing embodiments, after a network device joins a VSM instance, if it is determined that the network device is a standby member device in the VSM instance, the network device may actively report the current state of the network device to a primary member device in the VSM instance. By adopting the mode, the main member device in the VSM instance can determine the state of each standby member device in time, and sends the configuration request message from the management side to the standby member device with the configurable state, so that the standby member device locally executes the same configuration modification as the main member device. Compared with the prior art, the method and the system have the advantages that the timeliness and the accuracy of configuration synchronization between the standby member equipment and the main member equipment are improved, the main member equipment in the VSM instance does not need to send the state confirmation message to the standby member equipment regularly, and the burden of each member equipment processor and the VSM data transmission channel is relieved.
In order to further improve timeliness and accuracy of configuration synchronization between the standby member device and the main member device, in an example, after receiving a configuration request from a management side, the main member device in the VSM instance may send a status confirmation request to the standby member device in a non-configurable state, in addition to sending the configuration request to the standby member device in a configurable state. The standby member device whose state is not configurable may return its current state to the primary member device after receiving the state confirmation request, and if the current state returned by the standby member state is configurable, the primary member device may update the state flag of the standby member device from unconfigurable to configurable, and send the configuration request to the standby member device, so that the standby member device locally performs the same configuration modification as the primary member device based on the configuration request.
In another example, if a certain standby member device in a VSM instance is not reachable due to a ring network or the like, a primary member device in the VSM instance may detect that sending a configuration request to the standby member device fails based on error information returned by its socket, and the subsequent primary member device may send a status confirmation request to the standby member device. The standby member device may return the current state to the main member device after receiving the state confirmation request, and if the current state returned by the standby member device is configurable, the main member device may send the configuration request to the standby member device again. If the current status returned by the standby member device is not configurable, the status of the standby member device may be marked as not configurable.
in another example, the timeliness and accuracy of configuration synchronization may be further improved by a state validation process. Specifically, if the standby member device in the VSM instance receives the status confirmation request from the primary member device in the VSM instance, and then the current status returned to the primary member device is unconfigurable, the primary member device may detect whether a status confirmation process for the standby member device exists. The state confirmation process is used for sending a state confirmation request to the standby member device according to a preset time period, and the standby member device can return the current state to the main member device after receiving the state confirmation request, so that the main member device can update the state of the standby member device in time.
In another example, if the main member device does not receive the current status returned by the standby member device within a timeout period preset by a user, the main member device may also detect whether a status confirmation process for the standby member device exists. Such as: the failure of the standby member device to receive the status confirmation request from the main member device or the failure of the main member device to receive the current status returned by the standby member device due to reasons such as a ring network, etc., may cause the failure of the main member device to receive the current status returned by the standby member device within the timeout period.
It should be noted that, when the primary member device in the VSM instance performs configuration synchronization, if the secondary member device whose state is not configurable is found, the primary member device may alert the user to remind the user that the secondary member device fails to successfully implement configuration synchronization with the primary member device.
In an optional embodiment, when receiving a first status message from a standby member device in a VSM instance, a primary member device in the VSM instance may start a status confirmation process for the standby member device; and when receiving the second status message from the standby member device in the VSM instance, the status confirmation process for the standby member device may be closed. In this way, if the primary member device fails to receive the second status packet of the standby member device in time, the primary member device may also update the status of the standby member device in time based on the status confirmation process.
