Embodiment Construction

[0049] SDH system tributary board light board time slot intersection time division optimization configuration method of the present invention is made up of following four parts:

[0050] A. The location of the incoming time slot can be on the optical board or on the tributary board.

[0051] B. Space-separated intersection matrix.

[0052] C. Time-division module, there may be one time-division module or multiple time-division modules.

[0053]D. The location of the outgoing time slot can be on the optical board or on the tributary board.

[0054] 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.

[0055] The SDH system tributary board optical board time slot time-division optimal configuration method of the SDH system branch circuit board described in the present invention is as follows:

[0056] In AU4 mapping mode:

[0057] Call the branch ...

Abstract

This invention relates to a SDH system to achieve optimal allocation of time slot time division on the spur track board including: analyzing all destinations AUG of the same spur track board group inthe mapping mode, selecting undistributed AU that appears most firstly to enter time module towards the spur track board with incomplete allocation, enacting the number of AU undistributed and signedto enter time module to count the bus number of TU signal modules occupation; selecting the time flow corresponding to the largest one of all the matching numbers enters time module; counting the matching number of the AU flow not entering time module and arranging those according to the conditions entering into the module.

Description

technical field [0001] The present invention relates to a method for optimal use of resources, in particular to an optical synchronous digital transmission network system implementing a time-division optimal configuration method for optical board time slots on branch boards in the field of communication. 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 thro...
