【摘要】 目前中国教育科研网在中国已经日益成熟,蓬勃发展,校园网在各高校中占据了越来越重要的地位和作用,让网络稳定高效的运行已成为各高校越来越关心的问题,一个功能完善的网络管理软件可以较好的保障用户更好的使用网络,因此研究网络管理软件有着重要的意义。本文基于SNMP协议,以石河子大学校园网为背景研究、设计和开发了SVIEW网管软件,主要完成了以下工作:研究和实现了以三层交换机为主的主干网络拓扑的自动发现,提出了一个新的算法实现链路层网络的自动发现,并能够较好的发现哑设备;研究和实现拓扑图生成与布局,精心设计算法与程序,使生成拓扑图更清晰;研究和实现自动告警模块,实现了手机短信告警、NetSend告警、消息框告警等方法;研究网络流量数据采集方法和流量形成方法,实现了网络流量监测;研究和实现了主机定位模块,为快速定位用户所在设备端口提供了好的方法。系统完成后在石河子大学校园网中试运行,稳定可靠,效果良好,达到了预定目标。更多还原

【Abstract】 Today CERNET has already gradually grown up. The development is flourishing in China. The campus networks have occupied more and more important position and effect widely in colleges and universities, where the network administrators pay more attention to make networks working stable and efficient. Because perfect network management software can make network operate better, so it is important to study and develop thepowerful network management software. The paper focuses on the design and development of SVIEW network management system based on SNMP protocol through the study on the campus network of Shi He Zi University. It has mainly accomplished the following jobs:Explore and implement the topology automatic discovery system mainly based on L3 switches in backbone network. It puts forward a new algorithm that has realized the topology automatic discovery of link layer. It can also discovery the dumb equipments. Explore and implement the network topology map generation and layout with well-designed algorithms and programming that make topology map more clearly. Explore and implement the automatic alarming module that realizes SMS alarm, the Net-Send alarm and messagebox alarm.Explore the data acquiring methods of network traffic and explore the formation of traffic,and implement the monitoring to the network traffic flow.Research and implement the host-locating module that provides a good way to determine the equipment port rapidly the user host connects to.After the system development completion, it has been running in Shi He Zi University campus network. Now the system runs smooth, stabile and reliable, and it has reached the original developing target and has good effects.更多还原
