基于NetFlow的网络流量采集系统设计

Design on NetFlow-based Network Traffic Data Collection

网络流量是网络运行状态的风向标,对网络流量的相关情况进行监测分析与研究是网络管理的重要环节。从网络安全视角,详细介绍流量分析中主要使用的NetFlow技术,并根据NetFlow的特点,给出了一个基于NetFlow的网络流量采集系统设计实例。

Network traffic is the network running status of the vane,for network traffic monitoring and analysis of associated conditions and research is an important part of network management.In this paper,network security perspective,detailed traffic analysis of the main use of NetFlow technology,and according to the characteristics of data flow of NetFlow,Provides us with a practical illustration of system design on collecting data of NetFlow.
