基于移动Agent的IP网络拓扑发现

IP- Network Topology Discovery Based on Mobile Agent

随着现代网络规模不断扩大和结构日趋复杂,网络管理成为网络系统正常运行的关键,其中网络拓扑自动发现是网管系统的基本要求和重要功能。通过网络拓扑发现,可反映某些重要服务器、路由器和交换机的布局状况,并提供可视化管理界面,如系统配置、节点状态和流量监控、异常告警等,对网络系统正常运行、防范网络攻击具有重要意义。本文提出一种基于移动Agent的网络拓扑发现改进算法,降低了拓扑生成的复杂度,提高了拓扑发现的自动化程度,网络管理员只需指定子网搜索深度,算法即可由近及远逐层自动发现子网、路由器及拓扑,减少了管理上的支持。

With the development of network scope and complexity of network structure,network management is the key to system＇s well-balanced running.Network topology_ discovery is the primary, demand and important function in the network management. Through topology discovery,the administor can find the layout of servers,routers and switches.The paper presents a improved arithmetic of topology discovery based on mobile agent,reduce the complexity of topology production,improved the automatization on topology discovery.The network managers specify the depth of the searching subnet,the arithmetic can automatically discover the subnets,routers and topology,lessen the support on management.
