可拓检测在动态负载均衡策略中的应用研究

在DNS动态负载均衡策略中,服务器负载状态的获取是控制的关键.现有的DNS负载均衡策略在状态获取的实时性、状态表示的合理性等方面都存在不足.针对这些不足,本文提出了一种新的动态负载均衡策略,把可拓检测技术的思想和模糊数学引入到负载均衡策略中,利用可拓学的物元、关联函数,可拓检测和模糊学的隶属度等概念来构建一个集群动态负载均衡策略模型.实验证明,在该策略模型中,利用可拓检测的思想来获取负载状态,能明显提高负载均衡策略的有效性、实时性、动态性和稳定性.

Application of Extension Detecting in Dynamic Load Balancing Strategy Model

In the DNS dynamic load balancing strategy,the key point is to get the load states of servers.The existing DNS dynamic load balancing strategies have shortages,such as the real-time states capture and the logical load states expression.In this paper,a new load balancing method,which is to connect extension detecting technology and fuzzy math with load balancing,is put forward.The method takes advantage of the concepts of matter-element,extension detecting,dependent function and the membership degree in exte...
