Problems solved by technology

[0005] Although the time-division module can realize any crossover of signals lower than the AU level, due to the limitation of the capacity of the single-time-division module and the influence of cross-time-division factors in the multi-time-division module, it still cannot solve the problem of resource allocation of a large number of low-order time slots. , so how to optimize the use of resources and save time-division modules while ensuring the configuration success rate has become a problem that must be considered in the time slot configuration process
[0006] If there is no good multi-time division processing mechanism, when the multi-time division module is configured in time slots, there may be a possibility that the time division resources are still partially idle, but the configuration cannot continue, or for the same time slot data, there may be different The order of issuing, sometimes succeeds and sometimes fails

example 2

[0055] The premise of Example 2: all outbound time slots have been configured in the time slots where the position of the time division module has been determined, and all space division cross-connects that have not undergone time division configuration have also been configured. All AU-level time slots have been configured with time slots.

[0056] Example environment: such as Figure 7 As shown, the capacity of the time-division module is 5×5AUG, of which the time-division module 1 (1# time-division module) has occupied 2×2AUG, and the time-division module 2 (2# time-division module) has occupied 3×3AUG. Figure 7 to Figure 10 The circled AUs in indicate the allocated AUs.

[0057] In the first step, the time slots to be configured this time are divided into irrelevant groups. For the convenience of description, the time slot is regarded as the intersection of services on a certain logical AUG and services on a certain logical AUG, and the factors of ports and boards are n...

Abstract

The invention discloses a multiple time division configuration method and device. The method comprises the following steps: dividing independence groups, wherein each independence group comprises one or multiple time slot inlet end and / or time slot outlet end-associated time slots; determining the independence group with the maximum number of the time slot outlet ends among the independence groups as the maximum independence group; and configuring the maximum independence group. According to the technical scheme provided by the invention, high configuration success rate can be ensured while optimal configuration of resources is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-time division configuration method and device. Background technique [0002] Optical Synchronous Digital Hierarchy (abbreviated as SDH) has been widely developed and applied in the field of optical communication. With the enrichment of social life and the advancement of technology, the demands in the field of optical communication are becoming more and more diverse. Optical networks can flexibly and quickly realize business adjustments, and will be able to better meet the various needs of different customers. This puts forward more stringent requirements for SDH equipment or network elements in terms of time slot crossover configuration. [0003] In the optical synchronous digital transmission network, if there is data transmission between two network elements or within a single network element, time slot configuration must be performed. The function of the slot config...
