摘　　要：中国互联网技术发展迅速,网络结构日益复杂。网络业务以及设备品种的增多导致网络运维人员培训困难,故障无法及时解决。为了提高通信网络和设备的运维水平,需要一个与实际SDH网完全一致的虚拟网作为通信网络运维和研发的基础。SDH系统仿真平台通过模拟SDH设备原型,有效实现SDH的底层传输机制,从而再现数据传输流程以及网络故障的产生过程。文章以SDH原型中TTF(传送终端功能)功能模块为例,详细叙述SDH原型机帧结构以及逻辑部件仿真思路。With rapid development of Intemet 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.
