Asymmetrical Self-adaptive Clock Synchronization Algorithm and its Application in SDH Net Synchronization Simulation

在SDH网络结构日益复杂,通信网络运行维护愈加重要的情况下,为了提高通信系统反事故和防事故的能力,克服传统反事故演习的缺陷,需要一个与实际网络运行一致的动态通信网络仿真。要仿真SDH通信网络,必须解决SDH网络同步仿真问题。主要介绍一种非对称式自适应时钟同步算法,并对时钟同步参数的计算给出详细过程,最后给出模型和实验,对算法性能进行分析。

With the development of communication technologies and the growing of new communication business,the entire network operation and maintenance are becoming increasingly important.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.At present,a large number of communication networks are using SDH.Therefore to simulate communication networks,we must study the simulation of SDH network.This dissertation proposes a non-symmetrical self-adaptive clock synchronization algorithm.It shows how to calculate clock synchronization parameters in details.Besides,it gives the model and experiments and analyze the performance of the algorithm.
