摘　　要：由多台服务器构成服务器集群系统来分担负荷，已成为避免网络服务器性能瓶颈的一种有效结构。传统服务器集群系统的负载均衡器担当了客户与真实服务器通信全过程的中介，致使负载均衡器容易成为系统的瓶颈。针对传统的服务器集群系统存在的不足，对传统socket通信模型进行了扩展。经测试扩展后的模型，很大程度上减轻了负载均衡器的负载，提高了系统的吞吐量和可扩展性。Server cluster system composed of several servers has become an efficient structure to avoid the performance bottleneck of network servers. Load balancer in traditional cluster server systems plays an intermediate role in the entire process of communication between clients and real servers, which tends to make the balancer the bottleneck of the system. To solve this problem, we propose an extension of socket model. It is tested that the extension releases the load of the load balancer and enhances the output and extensibility of cluster server system.
