Research Of Reliability Design Of Computer Communication Network

With the development of computer communication networks, the computer communication network is getting more and more important in the national economy. Since the development of all kinds of economy is inseparable from the computer communication network, research of its reliability has a vital significance.This article describes the importance of computer communication network reliability and its studying status first. Then we point out that redundant design is an important technololgy to implement to the network reliability, and study some basic principles such as IP protocol and so on. Finally we explain the principles of some commonly used physical devices in computer communication network, and reliability redundant theories such as the Spanning Tree Protocol, VRRP, and Ethernet channel.By studying the general reliability features, the computer communication network reliability measures and reliability redundant model, we design a provincial scale, and highly reliable computer communication network. We make use of the existing telecommunication ATM to design the network. Finally we also analyze the reliability of the program.
