Abstract
To efficiently provide two disjoint endtoend paths for working and protecting in multidomain networks is challenging the network industry The Backward Recursive PCEbased parallel approach PA for disjoint paths can achieve best computation performance at high cost of computation complexity and communication overhead In this paper we propose an enhanced PA EPA based on a nodifferentiated inBNs pair strategy to decrease the computation complex and communication overhead The simulation results show that the EPA scheme can effectively reduce the computation and communication overhead
