[0021] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0022] Figure 1 The bandwidth adjustment and correction method shown according to the embodiments of the present application includes:

[0023] Step S11: If the service bandwidth of the preset path is increased, obtain the connection admission control (CAC) opening state of the preset path;

[0024] Step S12: If the CAC is open, obtain the bandwidth carried by the tunnel layer where the preset path is located;

[0025] Step S13: If the bandwidth carried by the tunnel layer is exceeded, determine a target route for the service matching the preset path according to the adjusted bandwidth of the preset path and the preset routing policy;

[0026] Step S14: If the target route exists, adjust the preset path to the target route.

[0027] Among them, when adjusting the bandwidth of a preset path on the network management platform, if the bandwidth of the preset path is increased, it is necessary to determine whether the increase in bandwidth will exceed the bearing capacity of the tunnel. The network server obtains the adjusted bandwidth for the preset path bandwidth and determines whether CAC is enabled. When CAC is enabled, it further determines whether the bandwidth is over-limit. By querying the routing table and the Quality of Service (QoS) bandwidth table of the preset path, it further calculates and determines whether the bandwidth is sufficient. That is, whether the sum of all the bandwidths of the tunnel layer where the preset path is located is within the bearing range of this tunnel layer. If it is over-limit, it is necessary to adjust the routing of the preset path to find the target routing that can match the service of the preset path. A path that meets the adjusted bandwidth, and for different users, the requirements for working pseudowires and protection pseudowires will be different. Users can select different protection routing strategies for over-limit paths with different priorities. The preset routing strategy is the routing strategy specified by the user. The target routing needs to meet the adjusted bandwidth and hit the preset routing strategy. When a routing that meets the user's expectations and has sufficient bandwidth is successfully calculated as the target routing, it is provided to the user to adjust the preset path. In this way, in the case where the user over-adjusts the bandwidth of the preset path, it can automatically identify over-limit bandwidth services and automatically provide the adjusted service routing, maximizing the guarantee that once bandwidth over-limit occurs, it can be immediately adjusted to a new routing to avoid service loss. At the same time, there is no need for operation and maintenance personnel to check and correct each path in a large number of paths in the live network one by one. It effectively reduces the over-limit bandwidth paths in the whole network, improves the reliability of the whole network paths, reduces the difficulty of operation and maintenance work, and reduces the operation and maintenance workload.

[0028] In one implementation, after obtaining the connection admission control (CAC) enabled state of the preset path, it further includes: if CAC is closed, return a bandwidth sufficient notification.

[0029] In one implementation, after determining the target routing that matches the service according to the adjusted bandwidth of the preset path and the preset routing strategy, it further includes:

[0030] If the target routing does not exist, return the reason information for routing matching failure. If the calculation of the target routing fails, the specific reason for the routing calculation failure is fed back to the user. For example, there is no routing that can meet the adjusted bandwidth, or the specified strategy of the user for the working pseudowire and the protection pseudowire cannot be met. The user can transform the live network according to the matching failure reason.

[0031] In one implementation, the "if the target routing exists, adjust the preset path to the target routing" includes:

[0032] If there are multiple target routings, adjust the preset path to the target routing with the minimum number of hops.

[0033] If the network management server selects the user-specified routing policy according to its service priority and calculates at least two routes with sufficient bandwidth, it selects the route with the minimum number of hops as the preset path for route adjustment.

[0034] In one implementation, the adjusting the preset path to the target route if the target route exists includes:

[0035] If there are multiple target routes, return the attribute information of the multiple target routes;

[0036] According to the obtained user selection operation, adjust the preset path to the target route selected by the user.

[0037] If the network management server selects the user-specified routing policy according to its service priority and calculates at least two routes with sufficient bandwidth, in addition to defaulting to selecting the route with the minimum number of hops as the preset path for route adjustment, it can also feedback these target routes to the user, and according to one of the target routes selected by the user, perform route adjustment for the preset path.

[0038] In one implementation, before obtaining the connection admission control (CAC) enabled state of the preset path when the service bandwidth of the preset path is increased, it further includes:

[0039] Add the CAC parameter to the quality of service (QoS) parameters.

[0040] The network management platform can download the bandwidth parameter when modifying the Ethernet service, but does not download the CAC parameter. If there is no CAC parameter, then when calculating the route, the bandwidth of the tunnel is not considered. Therefore, it is necessary to first complete the addition of the CAC parameter for modifying the Ethernet service on the network management platform.

[0041] Correspondingly, the determining the target route of the service matching the preset path according to the adjusted bandwidth of the preset path and the preset routing policy if the bandwidth carried by the tunnel layer is over-limited includes:

[0042] Judging whether the tunnel layer bandwidth is sufficient to bear the adjusted bandwidth according to the adjusted bandwidth in a loop;

[0043] If the tunnel layer bandwidth is not sufficient to bear the adjusted bandwidth, calculate the target route according to the QoS parameters.

[0044] Judge whether the bandwidth of the tunnel is sufficient for adjustment according to the adjusted bandwidth. Among them, determine whether the bandwidth of the tunnel is sufficient for adjustment by judging the bandwidth of the working pseudowire and the protection pseudowire in a loop. If the bandwidth is sufficient for adjustment, use the command code for adjusting the pseudowire bandwidth before to adjust the pseudowire bandwidth. If the tunnel bandwidth is not sufficient for adjustment, calculate the route using the new QoS parameters.

[0045] Example:

[0046] Figure 2 The shown bandwidth adjustment and correction method includes:

[0047] S201. Add the CAC parameter from the QoS modification interface of the portal of the network management platform UME.

[0048] S202. Keep the LCM interface of the network management platform UME unchanged.

[0049] The LCM interface is a conversion interface connecting the client and the network server, without any modification, directly passing through the commands.

[0050] S203. The Driver-UME calls the new F-port command code, and the request parameters and response parameters remain unchanged.

[0051] S204. Judge whether the bandwidth of the tunnel is sufficient for adjustment according to the adjusted bandwidth.

[0052] If the bandwidth is sufficient for adjustment, execute step S205; if the bandwidth is not sufficient for adjustment, execute step S206.

[0053] S205. Use the command code for adjusting the pseudowire bandwidth before to adjust the pseudowire bandwidth.

[0054] S206. Calculate the route of the tunnel using the new QoS parameters.

[0055] S207. Judge whether the calculated route is successful.

[0056] If the calculated route fails, execute step S208; if the calculated route is successful, execute step S209.

[0057] S208. Feedback the reason for the failure of adjusting the service bandwidth to prompt the failure of this bandwidth adjustment.

[0058] S209. Return the route result to the interface for display.

[0059] S210. Judge whether the obtained user feedback information is satisfactory.

[0060] If the user is satisfied and the obtained confirmation information is sent by the user, execute step S211, confirm the adjusted route, call the confirmed interface to modify the tunnel route, and return the result; if the user is not satisfied and the obtained information to abandon the adjustment is sent by the user, execute step S212 to end the route adjustment.

[0061] Add an identifier in the return result to indicate whether the route has been adjusted, and send a prompt message to the client: This modification of the bandwidth parameter has caused a change in the tunnel route. If this route change is prompted, query the route automatically once when switching to the "Route" panel.

[0062] The configuration is completed.

[0063] Through the above method, the route of the service after excessive bandwidth adjustment can be automatically adjusted, and the adjusted result is presented to the user in a visual form.
