基于SNMP的校园网络流量监测系统的设计与实现
|
摘要
随着计算机技术、网络通信技术的飞速发展,目前校园网络出现了多种不同的解决方案,可以采用多种不同思路和方法进行实现。研究这些不同网络中流量的特点对于提高网络的速度、克服网络的瓶颈具有十分重要的意义,是进行网络规划和优化的基础,也是网络管理中十分重要的组成部分。
本论文在分析SNMP协议和讨论传统网络管理模型中不足的基础上,提出了一种检测网络节点流量的实现方法和一种基于Web的三层网络管理模型。基于这个模型和方法进行了系统的总体设计和详细设计,并通过一些工具包实现了网络流量检测与分析系统。
该系统定时从网络节点路由器上读取网络流量数据,既可以获取路由器某个端口的总流量也可以获取动态IP流量表,同时将所得到流量数据经过分析和计算处理后存入相应的日志文件中保存起来,当用户需要数据时,就将相关数据调出来生成流量的PNG图片,并嵌入HTML页面中生动形象的显示给用户,让用户更方便更快捷的了解网络节点路由器的流量情况。为了保证读取出来的网络流量数据的完整性和准确性,该系统中采用了一种动态设定采集周期的方法。
With the rapid development of networks and communications technology, many different resolutions are proposed. And we can implement campus network in different ways. Researches on the characteristics of the traffic on these networks are very significant to the improvement of network speed and the elimination of bottle-necks. They are the foundation of network design and refinement. And they are very important components of network management.
This thesis through analyzing SNMP and discussing traditional network management model, put forward a kind of realization method that can examinate network node flux and a kind of three layer network management model that based on Web. According to this model and method, carry through the system total design and the system detailed design, pass the some tools realize network flux examination and analyze system.
The system can time read flux data of network node-router, since the total flux that can obtain a certain port in muter can also obtain the dynamic IP flux form, at the same time flux data can be deposited to the homologous log document, when user need these data, taking out the related data to make the picture of PNG, and put it into HTML page to give the user a vivid image of the flux data, letting the user can more faster and understand the flux instance of a network node .In the system the period of the data collection to make certain is very important, for the sake of guaranteeing the data integrality and the data security, the system adopted a method that enactment dynamic period.
