The Design And Realization Of A Safe And Effective Campus Boundary Network

With the rapid development of network technology nowadays.The construction of campus network accelerate university research and the development of education technology. It becomes a modern university education foundation platform, along with the universities construction, the constant expansion of the bottleneck problem and exports export safety problem is getting worse.Export once appear problem, which becomes a campus network information "separate island", and external lose touch.The construction of campus net border has become the top priority of campus network construction.So how to build a quick, stability and security of campus network of our export, we need to exploration and study.The background of this paper is a actual project. It's the "YunNan college of science and technology information" in KongGang campus of campus network. We research the boundary nets technology by this project. Through analysing challenges and difficulties of the modern campus net export, researching in depth on the key technology of boundary network construction. On the basis of further research, combined with the need of construction in YunNan college of science and technology information new campus. According to the network planning design theory, plan and design this campus boundary nets. And in the foundation of planning and designing, put forward the programme equipment selection.system deployment and the test scheme after completed.This design has fully regard for the current construction of campus net export demand, can realize export more, high bandwidth, rapid and stable,inner and outer net access.This article adopt Policy-based Routing, improve all the exits selected the bandwidth utilization rate.Using a VPN technology to realize the outside of campus network users within remote access; With deep packet inspection and bandwidth nested technology for control of the P2P software for important service to improve, the bandwidth of the normal and stable, realize the bandwidth management.Adopt IDS and firewall linkage technology, export from safe, to further enhance the outer net connection speed and protect access web server security, we have added a reverse proxy server.In do not need to change the premise of network topology structure, further improves export performance.
