摘　　要：数字图书馆会出现用户请求响应时间较长、服务器资源消耗较大以及集群环境中各服务器性能不同导致的网络负载不平衡问题。为解决上述问题,提出基于服务类型的负载平衡中间件模型。该模型考虑不同的服务请求对服务器负载状况的影响,结合各服务器的性能进行动态负载调度。性能测试结果表明,该中间件负载平衡效果良好,可用性与可靠性较高。There are some problems of high variable handling time of requests, high resource consumption of servers and load inbalance caused by different performance of servers in digital library systems. In order to solve the problems, this paper proposes a load balance middleware model based on service type. The model schedules every server dynamically according to the influence of requests on server load and the performance of servers. Performance test shows that the middleware solves the load balance problem effectively and has high usability and reliability.
