通信网建立时间同步网的方案探讨

Discussion about time synchronous methods in communication networks

从通信网体系结构入手,分析通信网层次结构与时延的关系。在对SDH网络层次结构分析的基础上,确定使用SOH中的MSOH来传递时间信号,以减小位置误差对时间不确定性的影响。

Starting with the system of communication network, the paper analyzes the relationship between its layer structure and delay. Based on the analysis of SDH network layer structure, the MSOH in SOH is made certain to transmit time signal to reduce the effect of position deviation on time uncertainty.
