摘要： 随着网络的发展，大型网站的访问量剧增，单台服务器已不能满足需要，负载平衡是解决这一问题的有效方式．分析现有的负载平衡方法，提出一种基于ＤＮＳ的异地服务器负载平衡新方法．该方法通过控制城名解析，将负载分配到各地服务器．其优点在于既可分散各服务器的负载，增强系统的稳定性，又可利用服务器分放各地的网络环境优势，缩短用户和服务器之间通信时间，提高服务质量，从而克服现有负载平衡方法的不足．

Abstract: With the development of the internet, the load of the popular sites has mounted up largely. The single server can't meet the need any longer, and the load balancing is the optimal method to solve it. Balancing the load of the servers in different places(BLSD) will not only spread around the load of the servers to enhance the stability of the system, but also can shorten the round trip time between the sevrer and the customer to improve the service. BLSD based on DNS (Domain Name Service) realizes the load balancing by controlling the resolving of the domain names. On analyzing the DNS,we could find that resolving the domain names is controllable, so we could resolve the domain names according to the need. BLSD is feasible. but there is something to do to improve it.
