【摘要】 随着通信技术的发展,新型通信业务的日益增多,整个网络的运行维护也日趋重要。传统的以"模拟操作"为主要特征的电力反事故演习方式虽然为保障通信网络稳定安全做出一些贡献,但是存在着诸多缺陷。为了提高通信网络事故处理的效率,克服传统静态反事故演习方式的缺陷,需要一个与实际网络完全一致的虚拟网络作为通信网络运维和研发的基础。而通信网络是以同步作为基础的,目前,通信网络中大量采用SDH,因此要仿真通信网络,必须研究SDH网络同步的仿真。本文提出对SDH网络同步进行仿真,并对其意义和内容进行了论述。更多还原

【Abstract】 With the development of communication technologies and the growing of new communication business, the entire network operation and maintenance are becoming increasingly important. Traditional "trial- use" as the main features of anti- accident exercise has made some contribution to the safety of communications network, but there are many defects. In order to improve efficiency to deal with the accident, to overcome detects of traditional anti- accident exercise, it is necessary to simulate the real communication network, which can be basic to the research and development of the communication network operation and maintenance. And it is known that communication network is based on synchronization. At present, a large number of communication networks are using SDH. Therefore to simulate communication networks, we must study the simulation of SDH network synchronization. In this paper, SDH network synchronization simulation is proposed, and its meaning and content are discussed.更多还原
