基于动态策略的校园网络高速访问的设计与实现

通过分析校园网多出口环境下与公网实现高速互访所需解决的问题,研究使用动态DNS、策略路由、NAT等关键技术实现不同的源/目的地址的数据包经由最佳路径策略所选择的出口发送/接收,以及在公网及CERNET访问校内域名时DNS动态解析出属于各自网内的IP地址,提出了应用于多出口校园网环境下与公网高速互访的实际方案,实现了校园网对外网提供高速网络服务,以及访问外网路由最优化.

Based on the strategy of dynamic high-speed access to the design and implementation of campus network

Analyzing the problem of the multi-outlet of campus network environment and the public network achieved the exchange of high-speed visits, using some key technologies such as dynamic DNS, policy routing, NAT, and achieving the data packet of different source（destination） address through the optimal path policy selected export transmission （reception） and exploring the DNS dynamic method to analysis the IP address belong to their respective network during a visit to the campus domain by the public network and CEtLNET. Using the actual plan,the high-speed Internet service of the campus network to outer network and the optimization of the accessing outer network routing are used.
