Embodiment Construction

[0048] The SDH system optical board lower tributary board time slot time division optimization time slot configuration method of the present invention is made up of following four parts:

[0049] A. The position of the incoming time slot can be on the optical board or on the tributary board;

[0050] B. Space-separated intersection matrix;

[0051] C, time-division module, there can be one time-division module or multiple time-division modules;

[0052] D. The location of the outgoing time slot can be on the optical board or on the tributary board.

[0053] A time slot from A to D can directly complete the entire crossover through B. If the crossover cannot be directly completed through B, it needs to be indirectly completed through C.

[0054] The time-division optimized time slot configuration method of the SDH system optical board lower branch time slot signal of the present invention is as follows:

[0055]In AU4 mapping mode:

[0056] Step 1: Arrange the location of t...

Abstract

The invention relates to an under-light plate branch time gap time diversion optimization configuring method for an SDH system, mainly comprising: in mapping mode, determining position arranging mode from TU time gap signal; for a branch plate whose configuration is not finished, preferring a to-be-allocated AU whose occurrence frequency is maximum to enter time division; setting number of to-be-allocated AU data, and number of AUs marked in time division to the branch plate, and calculating number of lower buses to be occupied by TU signal units corresponding to these AUs; selecting idle time division module and selecting a time gap flow corresponding to the maximum of all matching numbers to enter and be stationed in the time division module; for all the other AU time gap flows, calculating matching numbers and arranging AU time gap flows meeting conditions to enter and be stationed in the time division module. And it makes improvement in time division resources utilization, savingtime division resources and cost, and raising service configuration success rate.

Description

technical field [0001] The invention relates to a method for optimal use of resources, in particular to an optical synchronous digital transmission network system in the field of communication to realize the time-division optimal configuration method of the sub-branch time slot of the optical board. Background technique [0002] In the optical synchronous digital transmission network, if there is data transmission between two network elements and within the network elements, time slot configuration must be performed. The function of time slot configuration is to determine the specific cross path of the incoming and outgoing time slot for a given outgoing and incoming time slot. [0003] The outgoing time slot and the incoming time slot may be located on the optical board or the tributary board. A certain time slot can directly complete the outbound and inbound crossover through the space division crossover matrix, or can complete the outbound and inbound crossover through t...
