Abstract: In order to evaluate the reliability of a largcscalc real-life long-haul communication network, a method for computing network two-terminal reliability based on topology was presented. On basis of simplifying the topology, considering the reliability of edges and node, the two-terminal reliability was expressed by transfer matrices. The experiment results show that the edges being directed will have influence on various measures of network performance. Although the failure frectuency and the failure rate of the connection are quite similar, the locations of complex zeros of the two-terminal reliability polynomials exhibit strong differences. And the size of transfer matrices will become bigger with the increasing of network. I}he method is valuable for optimizing network and assigning the mean time of reparation.
