摘要 提出了一种动态负载均衡算法.该算法采用反馈原理,对系统中重要资源参数进行采集,并计算出实时反馈值,结合历史反馈值对系统中任务进行再分配以达到动态调整系统负载的功能.算法也可以通过反馈值对各connection接收任务的阈值做出动态调整以满足并行请求不同的情况.实验结果表明,使用该算法系统的读/写性能要比其他系统的读/写性能有所提高. Adynamic load balancing algorithm using a feedback control mechanism is proposed to improve the whole performance in iSCSI (internet small computr system interface internet) systems. This algorithm adopts a feedback technology, calculates much resource states that are collected in the system, and combines the results and the previous feedback's value in order to dynamically adjust the load state. The test results show that the performance of iSCSI system is improved with algorithm.
