<p>The present invention relates to a method for route distribution in multi-service optimization of SDH transmission network. Said method includes following steps: A) dividing the transmission network into subnets according to rings, and calculating the original route according to the service requirement in the transmission network; B) judging separately whether the link resource of inter-ring-subnet and intra-ring-subnet are overloaded, and if so, then recalculating the transmission route, C) deciding whether the ring subnet meets the requirement of load balance, and if not, then adjust the transmission route; D) judging whether the integrate index of the core subnet meets the convergence condition after dividing the subnet into the edge subnet and the core subnet, and if not, then judging whether the route calculating times reach the threshold, if so, then ending the process of route distribution, otherwise recalculating the transmission route. The present invention improves the calculating efficiency of route distribution in the large-scale network, and only needs less network resource, at the same time, optimizes the load balance of network.</p> |
