A Method of Network Traffic Analysis Based on sFlow
Hong Wang · Computer Engineering and Science · 2007
With the wider applications of the network, the key enterprise applications rely more and more on it.The small changes in the use of the network can bring great impact on the performance and reliability of the network.So it is a challenge and important research topic to give a full-range,high-speed and real-time network traffic analysis and performance analysis.Previous traffic monitoring and measurement techniques(such as RMON,NetFlow technology)have many flaws, and only the sFlow technology can look through the modern high-speed and complex network.Using the sFlow technology can capture the various raw data,but it is not enough to get this raw information,and we have to analyze the raw data and obtain the performance information for the network manager from the raw data.This paper proposes a method to analyze the traffic using the sFlow sampled raw data,and gives a framework of traffic analysis based on sFlow.
