Research on Simulation of SDH Prototype System
Xusheng Fang · Computer Era · 2009
With rapid development of Internet technology in China,the network structure is becoming more and more complex. The increasing of the network business and the variety of equipments make the training of the network maintenance man more difficult,and failures can not be resolved in a timely manner. In order to improve the operation levels of communication network and equipments,we need a virtual net which is fully consistent of actual SDH network as the basis of communication network operation and R D. SDH system simulation platform will carry out the underlying transport mechanism about SDH effectively by simulating SDH equipment prototype,and then reproduce the process of data transmission and the production of a network failure. Taking the TTF (transport terminal function) function module of SDH prototype as an example,we will describe frame structure of the SDH prototype system in detail,as well as the ideas of the logic components simulation.
