Laiwu Vocational And Technical College Campus Network Security Research And Design Strategy

With the expansion of the informationization of the Vocational and Technological College in Laiwu these years, campus network had gotten great development that includes online work, lessons preparation, studying and amusing, etc. The data announced by the Science and Technology Development Centre of Ministry of Education shows that 98.4% of the universities have used the teaching, scientific research, and ad work, 90.5% of the schoolrooms have provided campus network ecosystem, 74.35% of the students dormitories have had access network, so has the the Vocational and Technological College in Laiwu.It is very important for the security and stabilization of the campus network since we have been relating to it. We will develop more application and open for more users, which contradicts with the security and stabilization. All that urges us to write this thesis.Firstly, studying the threat of the campus network and analyzing the limitation of TCP/IP, we found many kinds of cyber attacks, expatiated the distributed Dos and solutions of the physical security of the college.We Study the reliability design of the large-sized campus network, and design a program that can get DRR and lord balancing when IDC is visited or the same subnet visits each other in the spanning multiple switches according to VRRP and MSTP, which ensures mission-critical function well and gets reliability design of the network.We expatiated backbone networks, routing protocol, way out or safty design, zone server design, VLAN design and IP schemes. We also design counter measures for ARP.Our study finds a way in building campus network. The design can be applied to the enterprises network environment of the same technology structure, which is important to enhance the network safety and the users' safety sense, to specify the network uses.
