浅析分组传送网和传统MSTP网络混合组网

摘要

Because the traditional voice business is increasingly weakened and the needs for the data services become more and more, the operators shift to packet transport network in the network construction. Due to the large network base, the deployment of packet transport network will be slow, which may lead to the packet transport network coexisting with MSTP network and occur mixed networking. The characteristics of packet transport network and traditional MSTP network are analyzed. Based on the different principles, the integration method and docking of the two networks are proposed with different ideas and their advantages and disadvantages are discussed.%随着传统语音业务比重越来越弱化，数据业务的需求越来越多，各运营商网络建设都向分组网偏移。由于目前网络基数已经很庞大，部署分组网将是一个缓慢的过程，这就可能出现分组网与现有MSTP网络并存的情况，并有可能出现混合组网。分析了分组网和传统MSTP网络各自的特性，并基于各自不同的原理，对两种网络的融合方式、对接提出了不同的思路，并讨论其优劣性。
