【摘要】 在对服务器集群Web QoS控制基础上,综合考虑请求内容和各服务器性能以及当前整个集群负载平衡状况,设计了一种基于L4/L7双层分配的混合负载平衡调度策略,算法引入了一个反馈环节动态地改变Web服务器的权值,通过负载平衡程度的阈值进行判断,选择不同的调度策略,从而提高了Web集群系统的性能。更多还原

【Abstract】 On the basis of web-server control clusters with QoS, based on L4/L7 switching, a mixed load balance strategy is designed, which takes into account content of request, server performance and overall equilibrium state of the cluster load. Algorithm introduces a feedback loop which dynamically adjusts the weights of servers, by choosing different strategy according to thresholds of load balance, the performance of the Web cluster system is promoted.更多还原
