摘要
本文研究了采用基于SDH的多业务传送点(MSTP)传输网构建广域保护传输专线通道的时延特性,并提供了组网方案,通过京张高铁的工程应用及网络测试,总结了MSTP传输系统组建广域保护通道专线网络的解决方案,对类似工程具有参考价值。
The paper studies the transmission delay characteristics of wide-area protection transmission channel which is constructed by using SDH-based Multi-Service Transport Platform(MSTP)transmission network and it provides accordingly the networking scheme.Through the engineering application and network test of Beijing-Zhangjiakou high speed railway,the solution for MSTP transmission system to build a wide area protection channel dedicated network is summarized.It has reference for the similar projects.
