摘　　要：基于VIEW和策略路由的方案在双链路或多链路校园网中的广泛应用,使公众网访问校园网时DNS解析超时的问题凸显出来。本文结合实际,针对拥有www.xxx.edu.cn和www.xxx.cn双域名的双链路校园网,提出DNS加速方案并进行原理分析及实施,对复杂结构下DNS的配置有一定的参考价值。The abroad application of the scheme based on VIEW and policy routing in double Egress or Multi Egress of the campus network. aggravates the delay of DNS resolving when the ChinaNET accesses to CERNET.Based on the campus network which has double domain names(www.xxx.edu.cn and www.xxx.cn) and double Egress,this paper brings forward the DNS accelerator scheme and makes principle anaysis and its implementation.It can be of some reference value for the DNS configuration of the complex structure network.
