基于IP网络的自动拓扑搜索算法

目前局域网规模不断扩大、结构日趋复杂,网络速度及网络管理成为网络系统正常运行的主要指标及关键,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.要求网络拓扑发现速度快并可反映使用权级而决定服务内容、服务器、路由器和交换机的布局状况,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(广度优先搜索算法),降低了拓扑生成的复杂度,从而提高了系统速度.

An Automatic Topological Search Algorithm Based on IP Network

Against the background of the ever increasing size of local networks and the increasing complexity of their structure,the speed and management of networks have become the main indexes of and key to the normal operation of network systems.Particularly,network automatic topological search is a basic requirement and important function of a network management system.Fast network topological search speed and the reflection of power levels,the determination of service content,the distribution of servers,routers and switch boards,and the provision of visible management interface featuring system allocation,the status of nodes,the monitoring of flow and warning of abnormalities are of great significance to the normal operation of network systems and to the protection against network assaults.This paper advances an improved algorithm based on mobile Agent network topological search which can reduce the complexity of topological generation and therefore raises the speed of network systems.
