南水北调中线干线通信网组网与分析

The Networking and Analysis to the Backbone Communication Network in the Middle Route of the South-to-North Water Transfer Project

南水北调中线干线通信网，是一个线形的网络路由，是一种通信专网，根据中线干线的实际情况，它一个比较特殊的线形网络，又要有比较高的网络安全性。现在通信系统组成，南水北调中线干线通信组网方式、组网结构、接入网等方面，作出比较详细的分析，并对应急通信系统也提出了一点合理性建议。

The communication network of the Middle Route of the South-to-North Water Transfer Project is a linear network routing. According the actual condition of the main line, it is a special linear networks with higher network security. Based on the communication system, the com- munication mode, network structure, access network are analyzed. It put forward some reasonable suggestions to the emergency communication system.
