摘　　要：针对网络地址转换(Network Address Translation,NAT)被过度使用和路由不准确等造成校园网带宽被浪费、网速慢等问题,结合NAT技术和策略路由完成对校园网内路由的优化,并在BIND9的基础上,设计出可根据用户IP地址智能解析的DNS,实现资源访问路径更短,减少网络带宽浪费,从而提升网络的性能和效率。Due to excessive use of NAT(Network Address Translation) and inaccurate routing,the campus network bandwidth is wasted,and network speed is slow. In this paper,NAT and PBR(Policy-Based-Routing) are used to optimize the routing of the campus network.Based on BIND9,an intelligent DNS resolver is designed,which resolves one domain name to the different IP for campus users and others,and it ensures a shorter resource access path and reduces network bandwidth waste,thereby improving network performance and efficiency.
