摘　　要：介绍了在基于前端分配器负载均衡集群中单一前端分配器的局限。提出了一种新的集群服务器结构,使用集线器将多台前端分配器集连,通过对数据包散列令多前端并行工作,消除集群前端分配器的瓶颈。实验测试在第四层和模拟第七层负载均衡下,双前端分配器器能提供比单前端高50%到80%的负载能力。This paper presents the limitation of single dispatcher in the Dispatcher-Based Load Balance Cluster.It designs and implements a new cluster structure,in which Multi-Dispatchers are clustered with Hub,working separately to dispatch the hashed incoming requests.This new structure is designed to increase the capability of the front-end of cluster.The test result shows that,Multi-Dispatchers structure＇s performance increases by 50% using Layer-4 load bala nce approach,or 80% using simulated Layer-7 load balance approach,comparing to single-dispatcher structure.
