Detailed ways

The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

Embodiment one:

This embodiment provides a service tunnel migration method, please refer to Figure 1, including:

Step S101: Determine whether the service tunnel to be transferred into or out of the shared ring has been configured with a protection tunnel, if not, execute step S102, and if yes, execute step S103.

Step S102: Configure a protection tunnel for the service tunnel.

Step S103: Switch the service carried on the service tunnel to the protection tunnel.

Step S104: Migrate the service tunnel into or out of the shared ring.

Step S105: Switch the service carried on the protection tunnel to the service tunnel.

In order to better describe the service tunnel migration method proposed in this embodiment, in the embodiment of the present invention, the method of migrating a service tunnel into and out of a shared ring will be described respectively. Embodiments 2, 3, and 4 are descriptions of methods for migrating service tunnels into the shared ring, and embodiments 5, 6, and 7 are descriptions of methods for migrating service tunnels out of the shared ring.

Embodiment two:

This embodiment provides a method for migrating a service tunnel into a shared ring, as shown in Figure 2, including:

Step S201: Determine whether the service tunnel to be migrated into the shared ring has been configured with a protection tunnel, if not, execute step S202, and if yes, execute step S203.

Step S202: Configure a protection tunnel for the service tunnel.

Step S203: Switch the service carried on the service tunnel to the protection tunnel.

Step S204: Migrate the service tunnel into the shared ring.

Step S205: Switch the service carried on the protection tunnel to the service tunnel.

Before step S201, the method may further include: filtering out service tunnels in the entire network that can be migrated into the shared ring according to the target shared ring, and adding them as service tunnels to be migrated into the queue of service tunnels to be migrated into the shared ring. In this way, batch migration of service tunnels to the shared ring can be realized. After adding these service tunnels to be migrated into the queue, it is judged one by one whether the service tunnels in the queue have been configured with protection tunnels, and the protection tunnels are configured for the service tunnels not configured with protection tunnels. Determine whether the service tunnels in the queue have been configured with protection tunnels one by one, and configure the protection tunnels for the service tunnels without protection tunnels to ensure that each service tunnel has a protection tunnel, so as to ensure that during the batch migration process There will be no business interruption due to migration failure.

In step S201, the service tunnel to be migrated into the shared ring refers to the service tunnel to be migrated into the shared ring, and the service tunnel may be a linear service tunnel or a service tunnel from another ring network. Judging whether the service tunnel to be migrated into the service sharing ring has been configured with a protection tunnel refers to judging whether the service tunnel has a protection tunnel. Because the service tunnel and the protection tunnel can form a protection subnet, another way of saying this step is to judge whether the service tunnel to be migrated to the shared ring forms a protection subnet with the protection tunnel. The purpose of this step is to ensure that each service tunnel to be migrated into the shared ring has a protection tunnel, so as to ensure that the service will not be interrupted by using the protection tunnel in the subsequent migration process. If in this step, the configuration of the protection tunnel for the service tunnel fails, you can choose not to configure it, and you can no longer migrate the service tunnel to the shared ring; you can also check the configuration operation and correct the detected problems , after the correction, perform the switching operation.

In the above step S203, switch the service carried on the service tunnel to the protection tunnel, that is, perform a forced switching operation on the service tunnel. After the forced switch, the service will be carried on the protection tunnel, and no natural switch will occur before the switch is cleared operate. In the above step S205, the service carried on the protection tunnel is switched to the service tunnel, that is, the clear switching operation is performed on the service tunnel. After the clear switch, the service will be carried on the service tunnel, and the service tunnel will return to the natural state. The natural state means that services will be switched according to natural conditions and will no longer be subject to artificial constraints. If the switching fails in this step, you can choose not to perform the switching, and no longer migrate the service tunnel to the shared ring; you can also check the switching operation and correct the detected problems. After the correction, Perform the switching operation again.

After the above step S205, that is, after the service tunnel is migrated into the shared ring, and the service carried on the protection tunnel is switched to the service tunnel, the migration of the service tunnel has been completed at this time. In order to ensure that the services carried on the service tunnel can be smoothly transmitted in the shared ring, the protection tunnel corresponding to the service tunnel can also be moved into the shared ring. During the migration process, in order to ensure that the migration into the protection tunnel will not affect the work on the service tunnel, the protection tunnel can be migrated into the shared ring after performing a blocking operation on the service tunnel corresponding to the protection tunnel. After the blocking operation is performed, the service is carried on the service tunnel, and no natural switching operation will occur before unlocking. After the protection tunnel is migrated to the shared ring, the service tunnel corresponding to the protection tunnel is unlocked. Further, if the service tunnels are migrated in batches, the protection tunnels can be migrated after all the service tunnels that need to be migrated to the shared ring are migrated to the shared ring, and the services are also switched to the corresponding service tunnels. It is also possible to migrate the corresponding protection tunnel into the shared ring immediately after a single service tunnel is migrated into the shared ring and the services are also switched to the service tunnel.

In this embodiment, when the migration of the service tunnel to the shared ring fails, you can choose to continue the migration operation, or exit the migration operation, that is, perform a rollback operation on the service tunnel. Therefore, when the migration of the service tunnel to the shared ring fails, one of the following methods can be used to process the migration operation of the service tunnel: (1) Perform a rollback operation to restore the configuration data of the service tunnel to the state before the migration operation state, and switch the service carried on the protection tunnel corresponding to the service tunnel to the service tunnel. Further, if the service tunnel has been added to the queue to be migrated to the shared ring, it can be removed from the queue. This step can also be understood as rolling back the previous operations, that is, moving the service tunnel out of the shared ring and returning it to the state before moving into the shared ring. (2) Check the migration operation of the service tunnel, and after correcting the detected problems, migrate the service tunnel into the shared ring. After successfully migrating to the shared ring, switch the services carried on the protection tunnel to the service tunnel.

If the migration of the protection tunnel has not been completed, go to step S408.

Step S408: increase k by 1, and then execute step S402.

Step S409: end.

Embodiment five:

This embodiment provides a method for migrating service tunnels out of the shared ring, which is similar to the method for migrating service tunnels into the shared ring in the first embodiment above. Operation, see Figure 5, including:

Step S501: Determine whether the service tunnel to be migrated out of the shared ring has been configured with a protection tunnel, if not, execute step S502, and if yes, execute step S503.

Step S502: Configure a protection tunnel for the service tunnel.

Step S503: Switch the service carried on the service tunnel to the protection tunnel.

Step S504: Migrate the service tunnel out of the shared ring.

Step S505: Switch the service carried on the protection tunnel to the service tunnel.

Before step S501, it may further include: filtering out service tunnels in the entire network that can migrate out of the shared ring from the shared ring, and adding them as service tunnels to be migrated out to the queue of service tunnels to be migrated out of the shared ring. In this way, batch migration of service tunnels to the shared ring can be realized. After these service tunnels to be migrated are added to the queue, it is judged one by one whether the service tunnels in the queue have been configured with protection tunnels, and the protection tunnels are configured for the service tunnels not configured with protection tunnels. Determine whether the service tunnels in the queue have been configured with protection tunnels one by one, and configure protection tunnels for service tunnels without protection tunnels to ensure that each There will be no business interruption due to migration failure.

In step S501, the service tunnel to be migrated out of the shared ring refers to the service tunnel to be migrated out of the shared ring, and the service tunnel may be a linear service tunnel or a service tunnel from another ring network. Judging whether the service tunnel to be migrated out of the shared ring has been configured with a protection tunnel refers to judging whether the service tunnel has a protection tunnel. Because the service tunnel and the protection tunnel can form a protection subnet, another way of saying this step is to determine whether the service tunnel to be migrated out of the shared ring forms a protection subnet with the protection tunnel. The purpose of this step is to ensure that each service tunnel to be relocated out of the shared ring has a protection tunnel, so as to ensure that the service will not be interrupted by using the protection tunnel during the subsequent relocation process. If in this step, the configuration of the protection tunnel for the service tunnel fails, you can choose not to configure it, and do not move the service tunnel out of the shared ring; you can also check the configuration operation and correct the problems found , after the correction, perform the switching operation.

In the above step S503, the service carried on the service tunnel is switched to the protection tunnel, that is, the forced switching operation is performed on the service tunnel. After the forced switching, the service will be carried on the protection tunnel, and natural switching will not occur before the switching is cleared operate. In the above step S505, the service carried on the protection tunnel is switched to the service tunnel, that is, the clear switching operation is performed on the service tunnel. After the clear switch, the service will be carried on the service tunnel, and the service tunnel will return to the natural state. The natural state means that services will be switched according to natural conditions and will no longer be subject to artificial constraints. If the switching fails in this step, you can choose not to perform the switching, and no longer move the service tunnel out of the shared ring; you can also check the switching operation and correct the detected problems. After the correction, Perform the switching operation again.

After the above step S505, that is, after the service tunnel is moved out of the shared ring and the service carried on the protection tunnel is switched to the service tunnel, the work of moving out the service tunnel has been completed at this time. In order to ensure that the services carried on the service tunnel can be smoothly transmitted in the shared ring, the protection tunnel corresponding to the service tunnel can also be moved out of the shared ring. In the process of moving out, in order to ensure that the moving out of the protection tunnel will not affect the work of the service on the service tunnel, you can perform a blocking operation on the service tunnel corresponding to the protection tunnel, and then move the protection tunnel out of the shared ring. After the blocking operation is performed, the service is carried on the service tunnel, and no natural switching operation will occur before unlocking. After the protection tunnel is moved out of the shared ring, the service tunnel corresponding to the protection tunnel is unlocked. Further, if the relocation of service tunnels is performed in batches, the relocation of protection tunnels can be performed after all service tunnels that need to be relocated out of the shared ring have been relocated out of the shared ring, and services have also been switched to corresponding service tunnels. It is also possible to move the corresponding protection tunnel out of the shared ring immediately after a single service tunnel is moved out of the shared ring and services are also switched to the service tunnel.

In this embodiment, when the service tunnel fails to move out of the shared ring, you can choose to continue the move-out operation, or exit the move-out operation, that is, perform a rollback operation on the service tunnel. Therefore, when a service tunnel fails to migrate out of the shared ring, one of the following methods can be used to handle the migration operation of the service tunnel: (1) Perform a rollback operation to restore the configuration data of the service tunnel to the state before the migration operation state, and switch the service carried on the protection tunnel corresponding to the service tunnel to the service tunnel. Further, if the service tunnel has been added to the queue to be moved out of the shared ring, it can be removed from the queue. This step can also be understood as rolling back the previous operations, that is, moving the service tunnel back to the shared ring, and making it return to the state before moving out of the shared ring. (2) Check the relocation operation of the service tunnel, and relocate the service tunnel out of the shared ring after correcting the detected problems. After successfully migrating out of the shared ring, switch the services carried on the protection tunnel to the service tunnel.

Step S704: Determine whether k protection tunnels have successfully migrated out of the shared ring, if the kth protection tunnel fails to migrate out of the shared ring, then proceed to step S705; if the kth protection tunnel successfully migrates out of the shared ring, proceed to step S706 .

Step S705: Perform a rollback operation on the k-th protection tunnel, restore its configuration data to the state before moving out of the shared ring, and remove the service tunnel from the queue.

Step S706: Perform an unlocking operation on the kth service tunnel in the queue of service tunnels to be relocated from the shared ring, so that it returns to the natural protection switching state.

Step S707: Determine that all the protection tunnels in the queue have been moved out of the shared ring. If the protection tunnels in the service tunnel queue to be moved out of the shared ring have been migrated out, the process ends. If the protected tunnel has not been moved out, go to step S708.

Step S708: add 1 to k, and then execute step S702.

Step S709: end.
