负载平衡是分布式系统中的一个重要研究课题,也是一个尚未解决的难题。负载平衡对于提高整个分布式系统的性能,特别是改善系统响应时间是很有意义的。本文在分析已有的算法的基础上,提出一种以分配为主、调整为辅的复合式算法来实现分布式系统的负载平衡。这个算法包括四方面的策略。即:负载的估算策略、负载信息的交换和更新策略,进程的分配策略和进程的调整策略。 Load balancing is an important research topic in distributed systems. It is also an unsolved problem. Load balancing makes great sense to improve the performance of the entire distributed system, especially to improve system response time. Based on the analysis of the existing algorithms, this paper proposes a hybrid algorithm based on allocation and supplementation to achieve the load balancing of distributed systems. This algorithm includes four strategies. Namely: the load estimation strategy, load information exchange and update strategy, process allocation strategy and process adjustment strategy.
