In order to reduce the redundancy of network resources assignment,the cost of resources configuration,and guarantee the survivability requirments,it provided the Multi-backupable based cross-layer resources optimization method.This method classified multi-hops service to three classes based on Diffserv model considering the different requirements of different service,and used different resource assignment method to different service classes;It provided the concept of multi-backupable,used inter-layer and intra-layer backup resources sharing at the same time based on the constraint that minimize the cost of resources configuration;Finally,it analyzed the performance of the method,it indicates that this method improves the resources utilization,reduces the cost of resources configuration,maximizes the resources sharing in multilayer networks while guarantees the service survivability.
