摘要
负载平衡是提高分布式系统性能不可缺少的技术,同时也是系统高可用性、可扩展性、容错性的必然要求。该文在分析和研究负载平衡模型的基础上,提出了一种基于消息队列的负载平衡模型,并在此模型下改进了基于阈值的动态负载平衡算法,给出了一种自适应的动态负载平衡算法。最后,在J2EE平台下,进行了实验和性能比较。
Load-balancing is a necessary technology for improving performance of distributed system.Meanwhile it is requirement of high-availability,scalability and failover in distributed system.This paper presents a load-balancing model on the basis of researching other load-balancing models.We put forward an adaptive dynamic load-balancing algorithm by improving load-balancing algorithms based on threshold.We implement our algorithm and compare the performance with other algorithms based on J2EE.
