【摘要】 随着网站访问量的增加,一些网站往往有多个地理上分布的提供相同服务内容的服务器群组,因此需要进行负载均衡处理。文章概括分析了现有的几种负载均衡算法,并提出了两种基于DNS的负载均衡新方法。该方法通过域名解析,根据每个服务器的可用性、客户与服务器之间的距离,以及地理范围匹配值,按照从优到劣的顺序返回网站的多个服务器的IP地址。更多还原

【Abstract】 With the development of the Internet,the load of the popular sites has mounted up largely.A growing num-ber of providers deliver content from multiple servers to reduce response time.So the load of the servers should be bal-anced.This paper analyzes several load balancing algorithms ,and introduces a new DNS-based.Algorithm,according to the availability of the servers,the latency time from the client to the servers and the matching weight of geography,it return s the IP addresses of the servers to client in the order from the best to worst.更多还原
