异构服务器集群的一种通用负载平衡模型

A General Medal of Load Balancing in Heterogeneous Web Server Clusters

集群的负载平衡问题是评价集群系统性能的重要指标。目前,各种负载平衡算法层出不穷,但由于这些算法往往基于特定的集群结构,因此非但不具备通用性,尤其是对于异构集群,造成了软件资源的极大浪费。本文提出了一种通用的负载平衡模型,旨在充分合理利用已有负载平衡算法的基础上,更进一步提高算法的可重用性和可扩展性。

Keeping load balance is one of the most important targets of clusters. Nowadays, all kinds of load-balancing algorithms are presented. But they are always based on certain architecture of clusters. Then they cannot be used in other surroundings, especially in heterogeneous architectures. Moreover, it wastes most of the software resources. In this paper, a general model of load balancing is presented in order to make full use of resources and improve the scalability and the sharable ability.
