All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a method and a system for scheduling an optical cable cutting task, aiming at the problems of the existing optical cable cutting task scheduling mode. The optical cable cutting scheduling system is introduced on the basis of a resource management system and a management control system (a network management system or an SDN controller) of the existing transmission network and is responsible for completing the formulation, verification and execution of an optical cable cutting plan, and the aim is to migrate affected services before the optical cable cutting, so that the service interruption caused by the optical cable cutting can be avoided, and the customer experience is improved.
First, a cable cutting task scheduling system according to an embodiment of the present invention will be described with reference to fig. 1.
Fig. 1 is a schematic structural diagram of a scheduling system for a cable cutting task according to an embodiment of the present invention. As shown in fig. 1, the scheduling system for optical cable cutting task in this embodiment includes: a cutting plan making unit, a current day cutting plan checking unit and a cutting plan executing unit.
The cutting plan making unit is mainly used for receiving a cutting task from a cutting task work order system, and then distributing the cutting task and making a cutting plan according to the optical cable-link-circuit mapping relation information acquired from the resource management system.
The on-day cutover plan checking unit is mainly used for receiving the on-day cutover plan from the cutover plan formulating unit every day T1, and then checking the cutover plan according to the current network state and fault information acquired from the transmission network management and control system. And feeding back the cut-over tasks which are not verified to pass to the cut-over planning unit for deferred redistribution.
The main function of the cutting plan execution unit is to receive the cutting plan of the current day from the cutting plan verification unit of the current day at the time of T2 every day, and then send a service migration instruction to the transmission network management and control system to complete service migration. And when the next day T0, after the optical cable cutting task is completed, requesting to exit the cutting state, and determining whether to return to the initial working path by the migrated service according to a preset rule.
The method for scheduling the optical cable cutting task according to one embodiment of the present invention is described below with reference to fig. 2.
Fig. 2 is a flowchart illustrating a scheduling method for a cable cutting task according to an embodiment of the present invention. As shown in fig. 2, the method for scheduling an optical cable cutting task in this embodiment includes:
step S202, a cut-over optical cable link circuit mapping table is obtained from the optical cable resource management system.
In the cut-over optical cable link circuit mapping table, each optical cable corresponds to a plurality of optical fibers, wherein each optical fiber corresponds to one link; each link corresponds to a plurality of circuits, wherein each circuit corresponds to one service, and the optical cable link circuit mapping table can inquire that each circuit has the protection attribute of the corresponding service.
And step S204, judging whether the standby path of the service carried by the cutting task optical cable comprises the cutting task optical cable or not by utilizing the path information of the service carried by each optical cable in the cutting optical cable link circuit mapping table.
If the optical cable does not contain the cutting task, the service carried by the optical cable of the cutting task does not need to be migrated when the cutting task is executed.
If the optical cable contains the cutting task cable, step S206 is executed to determine a backup path not containing the cutting task cable for the service carried by the cutting task cable.
If the service carried by the cut-over task optical cable is the non-protection switching service, a standby path which does not contain the cut-over task optical cable is reset for the service carried by the cut-over task optical cable.
If the service carried by the cut-over task optical cable is the protection switching service, the optical cable cut-over task on the standby path of the service carried by the cut-over task optical cable is delayed.
And step S208, when the optical cable cutting task is executed, the service carried by the optical cable of the cutting task is transferred to a standby path which does not contain the optical cable of the cutting task.
In the above embodiment, according to different service protection types, the optical cable cutover task scheduling system may automatically make an optical cable cutover plan and automatically process a cutover task. Meanwhile, the embodiment supports the processing of the conventional cutover request and the emergency cutover request, and supports the migration of the affected service before the cutover, thereby avoiding the influence of the cutover on the service, improving the customer experience, and reducing the network operation cost while improving the operation efficiency.
A method for scheduling a task of optical cable cutting according to another embodiment of the present invention is described below with reference to fig. 3.
Fig. 3 is a flow chart illustrating a scheduling method of a cable cutting task according to another embodiment of the present invention. As shown in fig. 3, on the basis of the embodiment shown in fig. 2, after step S206, the method for scheduling an optical cable cutting task in this embodiment further includes:
step S3071, a list of failed links is read from the transport network management and control system.
And step S3072, before the optical cable cutting task is executed, judging whether a fault link exists in the standby path which does not contain the optical cable of the cutting task according to the fault link list.
If a faulty link exists and the service carried by the cut-over task optical cable is the non-protection switching service, step S3073 is executed to reset a backup path which does not include the cut-over task optical cable and does not have the faulty link for the service carried by the cut-over task optical cable.
If a faulty link exists and the service carried by the cut-over task optical cable is the protection switching service, step S3074 is executed to postpone the optical cable cut-over task of the cut-over task optical cable.
In the above embodiment, according to different service protection types, different scheduling strategies are adopted to avoid the influence of a faulty link on the scheduling of the optical cable cutting task, so as to further improve the customer experience, and further reduce the network operation cost while further improving the operation efficiency.
An application example of the scheduling method for the optical cable cutover task of the present invention is described below with reference to fig. 4A to 4F.
Fig. 4A shows a work flow chart of the cutover plan preparation unit and the on-day cutover plan verification unit.
And the cutting plan making unit acquires the cutting task after X days from the cutting task work order system, wherein X is a positive integer. And then, the network topology and service information database acquires the network topology and service information from the transmission network management and control system, acquires the optical cable information from the optical cable resource management system, performs task allocation by a one-week cutover task allocation module to form a one-week cutover plan, and reports the one-week cutover plan to the console, and meanwhile delays the to-be-processed cutover task group which is not allocated in the one-week cutover plan for one day and then performs cutover plan reallocation. And for the temporary cutting task, after the temporary cutting task is verified by the temporary cutting task verification module, a cutting plan within X days is regenerated and reported to the console. And the console sends a cutting plan notice within X days to the cutting task work order system.
According to the fault link list, the cutting plan checking module can check the cutting plan and lock resources for the cutting plan on the same day after checking. For the 1+1 protection service, if the cutting plan obtained by verification needs to be adjusted, distributing the cutting tasks which cannot be processed to a cutting task group to be processed; for unprotected services, if the cutover plan cannot be corrected, a circuit interruption early warning can be sent.
Fig. 4B shows a work flow diagram of the cutover plan execution unit.
For example, a cutover plan is executed at time T2 every day, and protection switching traffic (or 1+1 protection traffic) is processed one by one. After the service switching is completed, entering a cut-over state, if the switching is successful, processing the non-protection switching services (or called as unprotected services) one by one; or if the switching is not successful, the cut-over optical cables passing through the circuit are placed into a cut-over task group to be processed, and then the console is informed to terminate the cut-over of the relevant optical cables. And performing soft rerouting when the non-protection switching service is processed one by one, if the soft rerouting is successfully cut, transferred and completed, and if the soft rerouting is failed, sending a circuit interruption early warning to the console.
In addition, the quit cutover operation may be executed at time T0 every day, and still be performed in the order of processing the protection switching traffic and the non-protection switching traffic one by one.
Fig. 4C shows a work flow diagram of the one-week cutover task allocation module of the cutover plan making unit.
And the cutting plan calculation module generates a temporary cutting plan and a temporary to-be-processed cutting task group. And for the temporary cutting plan, judging whether the number of the cut optical cables is larger than the maximum cutting amount Gmax every day. If not, generating a final cutting plan in the week; if the current cutting plan is larger than the preset value, the cutting optical cables exceeding Gmax are randomly removed, the removed parts are distributed to a temporary cutting task group to be processed, and then whether the last cutting plan of the week is formed or not is judged. If so, generating a cutover task group to be processed; if not, the cutting plan calculation module redistributes the temporary cutting task group to be processed.
Fig. 4D shows a work flow diagram of the cutover plan calculation module in the cutover plan preparation unit.
And the cut-over plan making unit screens out the protection switching circuit according to the cut-over optical cable link circuit mapping table, and then judges whether the main path and the standby path contain cut-over optical cables one by one. If so, putting the cut-over optical cable passed by the circuit main path into a cut-over task group to be processed, and updating a cut-over optical cable link circuit mapping table; if not, the cut-over task is scheduled until a cut-over optical cable link circuit mapping table meeting the protection switching circuit requirement is obtained.
And the cutting plan making unit screens out the non-protection switching circuit according to the cutting optical cable link circuit mapping table, and then judges whether the preset standby path contains the cutting optical cable one by one. If yes, recalculating the backup path for the circuit, determining backup path resources under the condition that the backup path is normal, and sending a circuit interruption early warning under the condition that the backup path is abnormal.
Fig. 4E shows a work flow diagram of the temporary cutover task check module in the cutover plan preparation unit.
The temporary cutover mission, the specific date cutover plan, and the day cutover plan all have respective priorities. Wherein, the temporary cutting task has low priority, and the cutting plan on the specific date and the cutting plan on the current day have high priority.
The process of the temporary cutting task check is similar to the calculation process of the cutting plan. The main difference is that in the process of judging whether the main path and the standby path all include the cut-over optical cable one by one, under the condition that the main path and the standby path of the protection switching service all include the cut-over optical cable, whether the temporary cut-over task specifies a specific date needs to be further judged. If yes, rejecting the temporary cutting task; if not, further judging whether the day-by-day processing is finished. If the day-by-day processing is finished, the temporary cutting task is rejected; and if the day-by-day processing is not finished, the temporary cut task is redistributed.
Fig. 4F shows a work flow diagram of the cutover protocol checking module in the cutover protocol checking unit on the same day.
The process of checking the cutting plan on the same day is similar to the process of making the cutting plan. The main difference is that after the fault link list and the cut-over plan are obtained, whether the fault link is carried by the optical cable to be cut-over or not is judged one by one. If not, further judging whether the fault link is related to the protection switching circuit to be carried by each optical cable: and if so, putting the optical cable to be cut into the cutting task group to be processed.
As can be seen from the above drawings, the design rule of the scheduling system for the optical cable cutover task is to pre-configure the backup path and not make resource reservation for the non-protection switching traffic (including, for example, unprotected traffic or dynamic restoration traffic). Before the cutover task is executed, the service needs to be migrated (i.e. soft rerouting and reserving the resources of the initial path), thereby ensuring that the non-protection switching service is not affected under the condition of resource permission. For the protection switching service, the main and standby paths of the protection switching service cannot be cut simultaneously, and pre-switching is required before cutting. For example, T2 (e.g., 23 o 'clock) on each day starts to switch the traffic in advance and sets the traffic in the cutover state, and T0 (e.g., 6 o' clock) on the next day sets the traffic in the normal state. The return mode of the cutting state is a non-return mode; during T2 to T0, when the current working path fails, protection switching should be attempted.
In terms of conventional cutover task processing, a cutover plan within X days needs to be locked, namely a cutover task request needs to be submitted X days in advance. The optical cable cutting and dispatching system calculates a cutting and dispatching plan within a week after X days every day. Meanwhile, the current network state (faults, link resource changes and the like) is used for verifying the current cutover plan, and the current cutover plan is updated according to the verification result.
In the aspect of processing the emergency cutting task, the cutting application recalculates the emergency cutting request (within X days) and the original cutting plan within X days, and if the emergency cutting request conflicts with the cutting plan within X days, the emergency cutting request is rejected.
In the aspect of processing a faulty link, after the arrangement of the cutting task on the same day is completed and before the cutting plan is started to be executed, if an optical cable fault occurs, whether the optical cable fault conflicts with the cutting plan on the same day needs to be judged, and if the optical cable fault conflicts with the cutting plan on the same day, the affected cutting task is notified to stop.
