The Design And Implementation Of Campus Network's Upgrading

With the fast development of Internet and the all-round implementation of basic construction to education network, informationization and network offer a new chance to university development.The main simple network built in 2000 of Shanghai Vocational College of Science and Technology can't bare the increasingly need of information. Thus, considering of the state of campus network application and supervisory, the leading group of college information decided to solve the problem by setting up special project.I luckily attended the whole project, the project aims to reform and design the present network of our college, also give a thoroughly study to some important technology of the network. In the first chapter, I mainly give a brief introduction to the formal construction of our network system and the contents of the thesis. The second chapter concerns with the present state of our network and state analysis. The third chapter is about a design of the campus network upgrade. In this chapter, I give a thorough analysis to the core layer, distribution layer and access layer and also a detail introduction to the different layers of different systems.The fourth chapter is a brief introduction to the realization process of network-upgrading modularization The fifth chapter is an intensive study to some core network technology.First, I talk about the redundancy, line redundancy in redundancy and load balance design , network device redundancy, load balance design, server redundancy, design, WAN redundancy.Second , I offer a analysis to the safe problems faced by network systems and give my detail design to the problems too based on the present network safe problems. We can realize effective network monitoring by the use of NAT,ACL,firewall,IDS and anti-virus system. Then we can find a solution to solve the problems of the campus network in monitoring and management.This network upgrading project is a synthesis of many network technologies, it has a better adaptability and can also offer a reference value to the construction other campus networks...
