摘　　要：企业信息门户(EIP)是连通"信息孤岛"的桥梁,为企业提供统一的信息入口,它已被越来越多的企业所依赖,同时,现代化农场企业也认识到了对信息进行收集与分析将会带来巨大的经济效益,因此当今许多农场都在利用EIP为企业提供可靠的信息资源。为了提高平台的可靠性和可用性,本文致力于将容错技术融入EIP的研究,并提出了一种基于队列的服务器集群负载均衡策略MC-QRD。结果表明,MC-QRD的负载性能优于已有的经典的调度算法。Enterprise Information Portal（EIP） is the bridge between the ＂islands of information＂, and provide a unified information entrance for the whole enterprise, there are more and more enterprises rely on it. At the same time, modern farm enterprises also realize that information collection and analysis will bring huge economic efficiency, therefore many farms now provide reliable information resource using EIP for enterprises. In order to improve the reliability and availability of platform, this paper hoped to make the fault-tolerant technology integrate into EIP, and proposed a new load balancing algorithm based on queuing, namely MC-QRD. The results showed that MC-QRD, as compared with some existing classic scheduling algorithms, achieved superior performance.
