摘　　要：针对校外用户访问天津音乐学院校园网资源所存在的速度瓶颈问题,制定了在校园网中使用Bind9软件架设智能DNS服务器,以及在边界路由器中应用端口地址转换(PAT)技术的联合解决方案.文中介绍了DNS的工作原理,而且还给出了架设智能DNS服务器,以及在边界路由器中应用PAT技术的具体配置过程.测试结果证明,该解决方案可行、有效.实现了校园网域名的智能解析,校外用户可直接通过自身所在的网域对校园网资源进行高速访问.In view of the speed bottleneck of users outside the school accessing the campus network resources of Tianjin Conservatory of Music,a joint solution of using Bind 9 software to set up an Intelligent DNS server in the campus network and port address translation technology in the border router is developed.This paper not only introduces the working principle of DNS in detail,but also gives the specific configuration process of setting up the intelligent DNS server and applying port address translation technology in border router.The test results show that the solution is feasible and effective.After the transformation,the campus network has realized the intelligent resolution of the domain name of the campus network.Users outside the school can directly access the campus network resources through their own domain at high speed.
