SDH Ring Network Route Choice And Time Slot Optimization Applications

With the gradual depth of modern digital communication transmission network coverage range, big scale increase of transmission bandwidth and the characteristics of transmission data flexibility continuously enhancement. SDH optical transmission Net at LAN takes on 3G wireless bearer network; broadband data bearer network has inherent advantages. This theme in accordance with the local transmission network of Unicom is in actual demand of WCDMA configuration transmission networks, based on the shortest routing algorithm of a classifiable discussion; provide that the ring network configuration algorithm operations.This theme analyzes key technologies of SDH principle, ring network principle and operational path choice deeply, etc. summed up ring network configuration algorithm that based on the shortest route. Firstly, this theme imported the shortest route and matrix mathematical model of sequential order by the enumerative way; and according to this algorithm, to provide more optimal algorithm. This algorithm under same condition of the shortest route considered the optimization program of sub-nodes odd-even number. Secondly, this theme used enumerative way to verify reliability and stability of the shortest optimal route algorithm.Finally, this theme used matlab 2006 platform to simulate this algorithm, this simulations show that the shortest route algorithm based on this sub-nodes odd-even discussion can meet the actual demand as far as stability and accuracy are concerned.In order to applying to this algorithm of sub-nodes odd-even discussion in project. The theme describes the application of actual network configuration. Firstly, converted the actual network topology graphic to business path flow graphic. Secondly, according to the sequence of business path flow graphic, to generate business configuration matrix. Finally, according to configuration result which business configuration matrix used matlab2006 environment to simulate, many engineering practice proved that accuracy and availability of this algorithm.
