校园网中域名动态解析的实现与应用

The Implementation and Application of Dynamic Domain Names for campus network

由于CHINANET和CERNET之间的带宽瓶颈,限制了公网访问校园网的速度。在双出口校园网中,利用DNS服务器的域名动态解析技术,可以使来自CHINANET和CERNET的请求分别访问校园网服务器的不同IP地址,从而充分利用双出口的带宽优势,加快公网访问校园网的速度。

Because of the bandwidth bottle-neck between CHINANET and CERNET, the public network can＇t access campus network at high speed. In the double-export-links campus network, the Dynamic Domain Names technology is used to resolve this problem. As the result, Request from different network will access different IP address of the same server. The public network can access campus network at high speed.
