摘要
Web服务是一项非常重要的网络技术,如何提高其的性能是一个热点问题。为了增强Web服务系统的容错性和扩展性,将负载平衡技术应用到Web服务领域。报告了负载平衡算法的现状,分析了Web服务对负载平衡的要求,给出了一个针对Web服务的动态负载平衡模型,介绍了动态调整模型中的服务耗费值、负载阀值和服务器权重的方法,及过载保护的方法。
Web services is a very important technology ofinternet applications. How to improve its performance is a hotpot. Dynamic load-balance is introduced to web services to augment its fault-tolerance and scalability. The current situation of load-balancing algorithm is reported. The necessity of web services load-balance is analyzed, and on this basis a dynamic load-balance model is proposed. Methods are presented in the framework to dynamically determine the resource consumption value of services and to adjust the load-thresholds and the weights of servers. Measures are also discussed for overload protection.
