1. Poor service security
Part of the in-use traffic cannot form a path due to configuration errors. Such as: the protection service is not configured, so that the normal protection switching cannot be realized by the service when the ring network breaks the fiber.
2. Service configuration inefficiency
The network management system has low use efficiency and slow response, and when the path management function is used for service configuration, the automatic path creation failure is caused by the occurrence of time slot conflict due to the existence of discrete services, and the path can be created only by designating time slots section by section.
3. Difficulty in locating fault

The project is expected to bring the following benefits:
1. the performance of the upgraded network management system is greatly improved, the operation and maintenance efficiency is improved, and the management risk is reduced;
2. the bandwidth resource of the network can be released, so that the service providing capability of the network is improved, and the performance of the network management database is improved;
3. low-order cross and port resources of the device can be released;
4. The end-to-end path management function can be more convenient to use, and the success rate of network management route calculation is improved.

The problems of numerous services, complex network structure and chaotic time slots of the power communication transmission network are common, so that the opening and maintenance of new services are difficult, and the service reliability is seriously affected. The time slot optimizing service refers to the optimization of SDH service to realize certain time slot allocation strategies, which include reducing the occupation of low-order cross resources of certain nodes, releasing partial VC4 service paths, ensuring the time slot consistency on MSP rings, reserving time slots and the like. The time slot allocation principles are confirmed together with the users, and according to the time slot allocation principles, the time slot allocation is carried out again on the existing network service, and the service is adjusted to the newly allocated time slot. The time slot optimizing service relies on the network management system to optimize time slots. The method specifically comprises information collection, time slot analysis, output of an optimization scheme, optimization implementation and test verification gatekeeper after optimization. In the whole process, the Hua-Cheng company guides delivery work according to the standard engineering implementation flow and the standard, and ensures the smooth implementation of the time slot optimization service.

Before optimization: each VC4 channel uses part of VC12, and is not full, if the VC4 level service is available in the future, the VC4 level service cannot be opened;
after optimization: one VC4 is occupied and the other VC4 is occupied, so that the whole VC4 time slot can be vacated to open large-particle service.
(2) Fig. 5 is a schematic diagram of another slot optimization approach according to an embodiment of the present invention, as shown in fig. 5, to solve the network security problem. And the time division cross adjustment is carried out, so that the traffic error connection is avoided. In the MSP ring, due to the existence of time-division crossover (change of VC12 slot number), after single-point failure or fiber breakage, service misconnection may be caused due to service switching, and such slot needs to be adjusted, so that the same service occupies the same slot number on one protection ring (same-ring simultaneous slot) as much as possible.
