低开销的网络流量检监测机制

Network Traffic Monitoring Scheme with High Efficiency

网络流量监测是网络管理的重要组成部分,数据包的捕获是网络流量监测的前提.但是,传统监测技术缺乏对网络流量监测并提供预警和预测功能.文中提出了低开销的网络流量监测机制.在捕获网络流量数据包后,对其分析,并以友好界面的形式将分析结果呈现给用户.基于此,实现了流量统计和流量预警机制.当网络流量出现异常时,系统可以及时地向网络管理员反馈,从而让管理员了解网络的运行状态及可能存在的危机,并做好相应的应对策略.实验表明,结果符合设计需求.

Network traffic monitoring system is the main part of network management, and how to capture the network data packets is the base, but traditional schemes lack of forecasting and alarm functions on network traffic with low efficiency. This paper proposes a network traffic monitoring scheme with high efficiency. In the scheme, we will analyze the captured data packets and put the good user interface on the analysis results to users. Based on the capturing and analyzing, the network traffic statistics and alarm has been implemented. When the network flow is abnormal, the systems can timely feedback to the network administrator, which allows the network administrator to understand the network running status and crisis and make some corresponding coping strategies. Experimentations show that the performance is good.
