一种新的服务器集群系统的设计与实现

互联网的飞速发展给我们带来极大便利的同时，也对网络服务器的性能提出了新的挑战。集群技术已成为解决服务器瓶颂问题的有效手段。本文在对服务器集群系统存在的瓶颈问题进行分析的基础上，提出了一种新的服务器集群系统解决方案。该方案通过对传统socket通讯模型进行扩展，并结合直接路由技术，有效地减轻虚拟服务器的负载；同时，通过采用主动自调度策略以解决真实服务器的瓶颈问题，对原型的测试表明该模型是可行的，且提高了服务器集群系统的性能。

DESIGN AND IMPLEMENTATION OF A NEW SERVER CLUSTER SYSTEM

As the development of Internet brings us great convenience, it is also challenging the performance of network servers. Therefore, server cluster technique has become an efficient method to solve the performance bottleneck problem of network servers. Based on deep analyses of the bottleneck problem of server cluster system, a new solution is proposed. The solution can release the workload of virtual server by the combination of the extension of the traditional socket model and direc, routing technique. Meanwhile, an automatic serf-scheduling mechanism is employed to solve the bottleneck problem of real servers. It is tested that the new model is feasible and can enhance the performance of cluster server system.
