The research and design of SDH transport network simulation platform

As the more complex of the transport network´s architecture, and the bigger of its scale, the analysis and management of the network fault is becoming more and more difficult. We need to do kinds of experiments to confirm various network breakdown phenomena in different networks and the influence which it brings to the service. But doing the experiments in real networks would bring some security risks, so we need to set up a series of network simulation platforms, analysis those network faults based on it. This paper presents a simulation program of SDH transport network, and mainly discusses the simulation method and content of SDH transport network.
