In the MSP ring, due to the existence of time division crossing (VC12 timeslot number change), after a single point fails or fiber is broken, due to service switching, service misconnection may be caused, and such timeslot needs to be adjusted, so that the same service occupies the same timeslot number (the same ring and timeslot) on one protection ring as much as possible. Such as the following scenarios:

before optimization: traffic is cross-hatched spatiotemporally at the site.

After optimization: traffic remains in the same timeslot throughout the MSP ring.

(3) Fig. 6 is a schematic diagram of another timeslot optimization method according to an embodiment of the present invention, as shown in fig. 6, the maintenance is orderly. And regulating the same-office-direction service. In addition to the basic requirement of compressing the time slot as much as possible, the scenario also hopes that the same VC4 is used for the services in the same office direction, so as to simplify the office direction of the services, but when there are many office directions, the usage rate of the VC4 resources on the line is high, such as the following scenario:

before optimization: the same VC4 channel bears a plurality of VC12 service office directions (for the office direction), and the service configuration is messy; due to the diversity of the service office directions of the same VC4 channel, the service punch-through configuration adopts VC12 level service particles, so that the network is low in price and serious in cross consumption.

After optimization: the same business office direction VC12 particle services are carried in the same VC4 channel, so that the business office direction is single, the service configuration is regular, and no hardware adjustment is needed; because the service office direction of the same VC4 channel is unified, the service collusion configuration adopts VC 4-level service particles, thereby reducing the low-cost cross consumption of the network and being convenient for maintenance and management.

(4) A service delivery is provided. Network management scripts can be collected before optimization, the resource utilization rate of the link and the node to be optimized is analyzed, the resource utilization rate after optimization is analyzed, and the optimization effect is presented through comparison. On the other hand, the time slot matrix table before optimization and the time slot matrix table after optimization can be manually recorded through a tool interface, and time division crossing and optimization effects on VC4 time slot occupation are presented in a contrast mode.
