基于移动代理的网络管理系统的响应时间分析

针对基于移动代理的网络管理系统的响应时间,提出了一个定量模型,从理论上详细分析了影响响应时间的主要因素,并就被管理的设备数,不同任务,与网络管理器的连接速率,设备之间的连接速率等对响应时间的影响进行了模拟实验.为了减小响应时间,提出并分析了访问固定数量设备的方法.结果表明,不同的任务对响应时间的影响较大,而与网络管理器连接的速率对响应时间的影响则较小,当访问一固定数量的设备时,会使相对应的响应时间最小.

Evaluating Response Time of a Network Management System Based on Mobile Agents

In order to reduce the response time for mobile agent-based network management system,we present a quantitative model to analyze the major factors that effect the response time.Various experiments are carried out in order to evaluate the effect on management response time:number of managed network elements,data rate between network elements and manager,data rate between network elements and task to be performed.Results show that the mobile agent is more influenced by the task to be performed and is less sensitive to the bandwidth of the bottleneck link that connects the management station to the remote LAN. Moreover,a significant improvement of the response time for mobile agent is obtained when the mobile agent sends data to the management station after visiting a fixed number of nodes
