高速光纤综合通信网络平台研究

摘要

The modern communication network should meet the development requirements of various communication services and communication capacities, and realize integrated switch and transmission of voice, data, video, IP, etc. Based on comparison of TDM, IP and ATM protocols, we propose an implementation method of constructing the network platform for optical fiber integrated communications by using MSTP platform with built-in RPR and MPLS functions. MSTP uses data frame structure on SDH and keeps standard optical interface on SDH, flexible add-drop low-rate signals, self-healing ring and powerful network management, etc. and can realize optimal transmission of TDM, IP and ATM protocols.%现代通信网络应能满足各种通信业务和通信容量日益发展的需求,实现话音、数据、视频、IP等业务的一体化综合交换和传输.在比较TDM、IP和ATM三种协议的基础上,提出"采用内置RPR和MPLS功能的MSTP平台"建设光纤综合通信网络平台的实现方法.MSTP采用SDH的数据帧结构,保持了SDH标准光接口、灵活分插低速信号、自愈环保护和功能强大的网管等优点,可对TDM、IP和ATM协议进行优化传输.
