摘要: 在分析和比较现有的基于分配器的服务器集群负载平衡方案的基础上,综合运用排队论知识和模糊控制理论,提出一种适合于小型Web服务器集群的模糊动态控制队列长度的负载分配器,该分配器在注重服务质量调控的同时,兼顾了集群的总体负载均衡。通过Visual C++编程构建模拟实验平台,验证了该方案的可行性。

Abstract: Based on analysis and comparison of existed load balancing program on the cluster server distributor, this paper studies a kind of dynamic fuzzy queue length distributor, which is suited to the small Web server clusters. The distributor focuses on the quality of service regulation, and overall cluster load balance. Feasibility of the scheme on the simulation platform programmed by Visual C++ is tested. Experimental results show that the scheme is effective.
