The research is to design and implement the optimization of the campus network of Putian University, this design by partitioning, hierarchical network structure, establishing a core equipment is composed of a plurality of three network architecture for the Putian University, to achieve a high availability, high resistance to attack ability of the campus network system, provides a good network platform based on network application unit, for college teaching, research, management and provides high performance, high bandwidth, security, stability and reliability of the network environment.The domestic and foreign about the security problems in the application and development of campus network in recent years are analyzed, starting from the existing campus network structure and network security situation of college, a more thorough discussion and Research on structural rationality, availability, antiviral attack capability, network management is convenient, intuitive., the deployment of a comprehensive network of integrated wiring design, selection of network equipment, network services, network security strategy, puts forward the design idea for the network system structure of campus network school development and solutions.The network structure was adopted in the design of Gigabit Ethernet technology is the most advanced, the core layer adopts Gigabit routing and switching equipment, and centralized and hierarchical network management model; the access layer, convergence layer and core layer connection speed to deal with distance education, online teaching, streaming media, multimedia and other business needs of campus network security precaution ability; enhance the immunity, network system can be improved, the reconstruction of the does not adapt to the weak link of the development and application of Internet, make the cyber source for optimal combination, the whole network system for safe. Technical scheme of the system combining OSPF and static routing strategy solves the load balancing and so many network applications of practical problems, the key link of the network routing design, the hierarchical structure of the L2loop solutions, security strategy deployment of network availability and anti-attack ability are discussed and analyzed deeply.By optimizing the reconstruction and upgrade of the construction of college campus network, campus network has a safe and reliable network security architecture, forming the system three level multi core ring multi-service network security.
