一种基于移动代理的网络性能管理模型研究

Model of Network Performance Management Based on Mobile Agents

对传统网络性能管理系统的缺陷进行分析后,提出了一种基于移动代理的网络性能管理模型.该模型通过将网络性能管理需要采集的对象和指令封装在移动代理内,利用Grasshopper移动代理平台进行支撑,实现了网络性能数据的自主采集,并利用被管网元的本地资源即时计算出最终的性能指标数据.通过对传统性能管理和文中提出的基于移动代理性能管理进行分析和比较,发现基于移动代理的网络性能管理可以减轻管理站的计算负荷,减少网络管理数据流量,从而降低因网络管理而带来的额外开销.

Analyzed the shortcoming of traditional network management system, then, a model of network performance management based on mobile agents was proposed. Model suggested encapsulating the objects and instructions with mobile agents. Mobile agents can independently collect performance MIB objeers node by node and compute the last performance data in local network entities in the model. We presented the architecture, design and implementation of such a model, compared and contrasted it to traditional poll mechanism implementation with experiment data. The data prove the model can decrease network overload and scatter compute tasks. We implemented the model by Grasshopper mobile agent platform.
