摘要
负载均衡就是如何进行对网络的访问分流,以便能够快速响应用户反应。分布式系统动态负载分配算法就是在程序运行过程中,能够根据各服务器上任务执行实际状态的变化,随时动态地调整任务分配,达到服务器负载均衡。本文分析了目前两种动态分配算法——集中式和分布式的利弊,并根据实际情况提出了一种新的动态负载分配算法,即半分布半集中式分配算法,并给出了具体实现方案,分析其性能。
Load＇s equilibrium is how net access is distributed so as to respond to user＇s reaction. Assigned arithmetic about distnbuted system s dynamic load is that can adjust dynamic assigned task at any moment in Program s running to enable server＇s load equipoise.This article analyses two arithmetic＇s advantages and disadvantages about dynamic load which are centralized and distributed.What is more,it bring forward a new assigned arithmetic about dynamic load which is half distributed and half centralized and how it is concretely realized and analvze it＇s nerformance.
