分布式系统中一种负载平衡调整算法的研究

Studies on A Load Balancing Adjustment in the Distributed System

1 前言 当前,随着计算机网络技术的高速发展,国内外关于分布式系统的研究逐步形成热点.在研究中,出现了大量成型的分布式系统模型[1].尽管如此,这些系统的实现手段和效率并不令人满意.目前还没有哪个分布式系统能用非常有效的手段和机制来克服由于分布而引起的问题,包括系统潜在的分布并发处理能力、速度、可用性和可靠性等等问题[2].

In this paper,we consider for the problems of process removal,process allocation and load distributing in distributed systems. We mainly raised and discussed a kind of process removal and allocation model,and some issues of load balancing adjustment and adaptive algorithms of dynamic feedback adjustment. On some database system which has complex middle ware, this model and algorithms provide a feasible method on raising system response speed and load distributing ability. We constructed imitative environment of the distributed system and proved the efficiency and property of algorithm model to present by experience.
