Electric Power Data Network Ip Bearer Network, The Way Research

To ensure the operation of the Sichuan Power Grid safely, economically and qualitatively, it needs to establish and put Sichuan integrated data transmission network into operation. According to the three-tier network structure , the core layer , backbone layers and the access layer . It sets the network management center in the dispatching and communication center,runs the network and operations management uniformly. With three hierarchy and IP technology and IP over SDH technology adopted ,the data communication network with high bandwidth and performance constructed on the highly reliable optical fiber transport channel. The Sichuan integrated data transmission network meet the requirement of related business for data transmission.This paper analyzes the problems of Sichuan integrated data transmission network from three aspects , network design , network security and data service connecting . And discusses the main factors of network design based on the following problems: the structure and implement mechanism ,the choice of technology type, the layout of IP network route, the route policy of users, etc..
