摘　　要：为提高DNS服务的响应时间,在分析DNS查询日志的基础上,提出了基于My SQL数据库的高可靠性缓存DNS系统,设计了该系统的框架结构,并在bind源代码的基础上使用C语言实现了该系统。通过大量域名对该系统进行压力测试表明,将DNS缓存存储于My SQL数据库相比传统DNS系统,在RTT max、RTT min、RTT average、Ran for、查询命中率和查询请求等方面都具有突出的性能,可大大改善DNS服务的响应时间。In order to improve the responsive time of DNS,based on analyzing query log of DNS,this study puts for-ward the highly reliable cache DNS system originating from MySQL database,designs its frame and realizes this sys-tem by using C language on the basis of bind source code. With the pressure of this system tested by a large number of domain names and comparing cache DNS system with traditional DNS system,it can be concluded that this sys-tem plays a proficient role in RRT max,RRT min ,RTT average,RAN for and query accuracy and request,eventu-ally greatly changes the responsive time of DNS.
