example 1

[0057] Example 1. Optimized use of the time division between optical board TU-level signal crossover and optical board TU-level signal

[0058] like image 3 As shown, issue the following two time slot commands:

[0059] 1: Optical board 1#AUG, 1#TU12 crosses to optical board 2#AUG, 1#TU12

[0060] 2: Optical board 3#AUG, 1#TU12 crosses to optical board 4#AUG, 2#TU12

[0061] According to the time slot configuration method from optical board to optical board, 1#TU12 of 1#AUG is crossed to 1#TU12 of 2#AUG. Since the position of the time slot number has not changed (1#TU12 corresponds to 1#TU12), the first time slot command The configuration can be directly spaced from 1#AUG to 2#AUG without time division. And 1#TU12 of 3#AUG is crossed to 2#TU12 of 4#AUG. Since the position of the time slot number has been adjusted (1#TU12 corresponds to 2#TU12), the configuration of the second time slot command is changed from 1#AUG It takes time to complete it. Configuration results 1#AU...

example 2

[0063] Example 2. Application of time-division AU time-slot stream in time-division module

[0064] Assume that there are 3 different marked time-division AU4 time-division time slot streams, which enter two time-division modules with a crossover capacity of 6*6.

[0065] 1: No. 1 AU4, No. 2 AU4, No. 3 AU4, No. 4 AU4

[0066] 2: 3rd AU4, 6th AU4, 7th AU4

[0067] 3: No. 1 AU4, No. 2 AU4, No. 5 AU4

[0068] According to the method of time-division AU time slot flow into the time-division module, such as Figure 5 shown. When entering the time-division module for the first time, the matching numbers of the three time-slot streams are all 0. First, the first time-slot stream enters the time-division module and occupies 4 time-division resources in the first time-division module. Calculate the time-slot stream 2 according to the above method , the matching numbers of 3 are 1 and 2 respectively, the time slot stream with the largest matching number is selected to enter the time...

Abstract

The invention relates to a time-division optimization configuration method for realizing optical board-to-optical board time slots in an SDH system. It mainly includes: in the mapping mode, configure time slots for the outgoing group AUGs that have not yet been marked with time division and space division; calculate the corresponding matching number for the time slot flow of each time division AU; the matching number is the number that has entered the time division module and all the numbers with the same AU number, the function of the matching number is to determine the order in which the time-division time slots flow into the time-division module; according to the size of the matching number, arrange the AU time-slot flows into the time-division module in turn; if all the time-slot data If the flow can enter the time division module, the time division configuration is successful, otherwise the time slot configuration failure information will be returned. The method of the invention has made progress in the use of time-division resources, achieved the effect of saving time and cost, and improved the success rate of business configuration.

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 communications to realize an optical board-to-optical time slot time-division optimal configuration method. 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 paths of the outgoing and incoming time slots for the given outgoing and incoming time slots. [0003] The location of the outgoing time slot and incoming time slot may be on the optical board or on 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 the...
