Abstract

A dynamic time delay model for load balancing was proposed in distributed heterogeneous system by Hayat. But how to compute the load-transfer delay and the gain coefficient were not gived, so it is imposible to quantitatively analyse the performance of a distributed system. In this paper, an improved dynamic load balancing model with load-transfer delay is designed for LAN, and the gain coefficient is defined by a number of simulation test, so to meet requirements of LAN. At last, the simulation test is presented. The conclusion is that the improved algorithm not only saves the resources, but also realizes a reliable and efficient operation of the system. So the improved algorithm can be used to the distributed system in LAN.

一种改进的局域网分布式系统动态负载均衡算法
Hayat提出了一种分布式异构系统负载均衡的动态时滞模型。但是如何计算负载传递延迟和增益系数没有给出,因此无法定量分析分布式系统的性能。本文针对局域网设计了一种改进的带负载传递延迟的动态负载均衡模型,并通过多次仿真试验确定了增益系数,以满足局域网的要求。最后进行了仿真试验。结果表明,改进后的算法不仅节省了资源,而且实现了系统的可靠高效运行。因此,改进的算法可以应用于局域网中的分布式系统。
