基于请求类型的数字图书馆负载平衡模型

Load Balancing Model Based Request Type

对于具有海量信息的数字图书馆,文章针对不同请求服务时间变化大的特性,提出基于请求类型的负载平衡模型,该模型根据各种不同请求对服务器负载状况的影响并结合各服务器的性能进行动态负载调度。避免占用服务器资源较多的请求同时分配到同一台服务器上。仿真结果表明该模型具有良好的负载平衡效果。有效地缩短了用户请求的响应时间。

For the digital library, this thesis proposes a load balancing model based request type in order to smooth extremely high variable traffic,combining the performance of servers, it schedules every server dynamically according to request's influence to server' load, therefore it can avoid distributing requests using more resources to the same server. Experiment results show the model effectively solving the load balancing problem and shortening response time of requests.
