摘要： 针对Web服务器的负载特点,利用模糊逻辑在线切换测量窗口的大小,提出了一种基于测量的接纳控制算法。该算法对服务器负载的变化有较强的动态适应性,不但有效地提高了对客户的接纳率和资源的利用率,而且也使得系统的丢包率控制在客户可容忍的指定范围内。

Abstract: This paper proposes a measurement-based admission control method for Web servers. In this method, server’s load characteristic is measured and the size of measurement window is online changed according to the measurements by fuzzy logics. The algorithm can dynamically adapt for variation of load flows well, and it can improve the admission rate and the resource utilization of the server, while keeping packet lost rate under the range that the client admits.
