一种分布式系统中动态负载均衡策略

A Dynamic Load-Balancing Algorithm for the Distributed System

在分布式系统应用中采用动态负载平衡算法分配系统中的工作负载,能够显著地提高系统的性能。针对 分布式系统中负载动态变化特性,提出了一种基于接收者主动的自索取动态负载均衡算法,通过负载数的实时变 化反映系统中各节点的当前负载状况,通过空闲节点来转移超载节点的任务,使负载的分布更均匀,提高了整个 系统资源的利用率及效率。

As the widely application of the distributed system, the dynamic load balancing policy improves the system performance markedly. There is larger difference among the loads of difference node in a distributed system. In this paper, the author proposes a dynamic load balancing policy on which accepter own initiative distributing base probability to assign each request to an appropriate node in terns of their weight. The author also provides the algorithm improving the whole system resources availability and efficiency.
