主动式集群中模糊逻辑及其改进研究

Fuzzy Logic and Its Improvement in Active Self-Allocating Cluster

网络带宽增长速度远高于服务器性能的增长速度,服务器越来越成为网络中的瓶颈。主动式集群就是为了解决服务器性能而提出的一种先进的集群技术,该技术的核心就是采用模糊逻辑来实现客户链接的分布调度。这里对其模糊逻辑技术进行研究,并提出了一些改进方法如增量式模糊控制,这些方法具有一定的理论意义,也具有实际的工程意义。在大部分应用中,可以采用这些方法对模糊逻辑控制进行改进。

Network bandwidth increases far beyond the performance of network server, so the server becomes the bottle - neck of the whole network. The active self- allocating cluster is one kind of advanced cluster technique, which is introduced to resolve the problem of server performance. Its core idea is to apply fuzzy logic control to realize the distributed allocating of client＇s links. This paper researches the fuzzy logic and gives several improving methods such as incremental fuzzy control, these methods are of both theoretic and practical value, and in most applications these methods could be used to improve fuzzy logic control.
