并行WEB服务器机群中实现动态负载平衡的请求分配策略

A Strategy of Request Dispatching for Load Balancing in Parallel Web Server Clusters

随着Internet的高速发展 ,采用并行WEB服务器机群系统是实现高性能Web服务器的一个有效途径 ,通过请求分配使机群达到负载平衡是提高这种系统运行效率的基本手段。本文在阐述相关技术的基础上提出一种实测与估测相结合的适用于同构和异构机群系统的请求分配策略 。

With the thriving of the Internet, Applying the Parallel Web Server Clusters system is an efficient way to achieving the high performance of the Web Server. And a basic method of improving the performance of the system is to balancing the Server Load by dispatching the requests. Based on the relevant technologies, this paper proposes an efficient algorithm of request dispatching to balance the whole system load dynamically. It dispatches the requests by analyzing the real time load and the Maximum Stable Connections (MSC). This algorithm can be applied to both the heterogeneous system and the homogeneous system.
