Research On Design And Security Of Informatization Network System In Colleges And Universities

Informatization network system in colleges and universities,a typical campus network, is the important foundation platform for our national informatization stratege,the most important link in educational informatization construction, and the important infrastructure of colleges and universities, serving as a platform for school teaching, scientific research,school management and foreign exchange.The pressing problem for us to solve in constructing it is to provide a reliable Informatization transfer channel, ensure safety in Informatization transfer process, and protect Informatization.Based on the author’s college actual network system’s characteristics, from two aspects of communication backbone network and safety protection, this paper makes an research into the design on the Informatization system of campus network, analyzing the reason of reforming backbone communication system and devising a completely new design for the backbone communication platform and presenting the layered architecture of communication system in order to ensure the safety of system operation. The author tries to describe the communication system design of the function modules of the layered architecture by using DMZ supporting the foreign service of the network communication system.Based on newly designed campus network communication platform, this paper makes a research into safety protection and makes an analysis of the influence of network system security and common security protection technology. Satisfying the needs of the practical application of our college, the MP2DR security model is designed based on user management, system management, physical security and safety protection technology. Two or three tunneling technology based on ISPec and L2TP protocol creates VPN networking and virtual firewall technology is used as the specific application technology of MP2DR security platform.Considering the complexity of campus network system and in order to ensure the Informatization transfer process routing optimal on QoS service security, this paper adopts the regional autonomy allocation strategy for the campus network system and by comparison of routing protocols, devises the final design of the ant colony algorithm for optimal routing OSPF protocol satisfying the QoS service selection of security communication system routing.
