【摘要】：互联网的兴起,迅速地改变了整个世界。在新经济时代下,网络已成为重要的基础设施,在通信、国防、金融、教育、交通等社会的各行各业里均得到广泛的应用。网络蓬勃发展的背后,是许多管理问题的纷至沓来。为了保证网络安全、有效的运行,人们对网络管理的研究也愈发重视。在这样的背景下,本文设计了基于SNMP的链路流量监测系统。该系统首先通过拓扑发现来获取网络的拓扑信息,然后再采用合理的布局算法进行拓扑布局,实现拓扑可视化；在拓扑可视化的基础上,对链路(节点端口)的流量进行监测。本系统分为拓扑可视化和流量监测两大模块。在拓扑可视化子模块的设计中,先分析了网络层和链路层拓扑发现存在的难点和不足,并给出了相应的拓扑发现算法；然后采用了基于分层的射线型布局算法进行拓扑布局。在流量监测子模块的设计中,采用了基于SNMP的单点流量监测方法。在论文的最后,给出了系统的原型设计,并且在实验环境下对流量监测模块和布局算法进行了验证。
[Abstract]:The rise of the Internet has rapidly changed the world.In the new economic era, the network has become an important infrastructure, in communications, national defense, finance, education, transportation and other social industries are widely used.Behind the vigorous development of the network, there are a lot of management problems.In order to ensure the network security and effective operation, people pay more attention to the research of network management.Under this background, this paper designs a link traffic monitoring system based on SNMP.The system firstly obtains the topology information of the network by topology discovery, then uses a reasonable layout algorithm to realize topology visualization, and monitors the flow of the link (node port) on the basis of topology visualization.The system is divided into two modules: topology visualization and flow monitoring.In the design of topology visualization sub-module, the difficulties and shortcomings of network layer and link layer topology discovery are analyzed, and the corresponding topology discovery algorithm is given.In the design of flow monitoring sub-module, a single point flow monitoring method based on SNMP is adopted.At the end of the paper, the prototype design of the system is given, and the flow monitoring module and the layout algorithm are verified in the experimental environment.
