一种基于小波谱的流量识别方法
Traffic Identification Method Based on Wavelet Spectrum
摘要
Abstract
Aiming at the problem of current traffic identification method limited by service port, protocol signatures and traffic encryption, this paper proposes a new traffic identification method based on multi-scale wavelet spectrum. The new method is able to achieve the identification of different network traffic by performing clustering analysis of K-means algorithm over the different scales wavelet spectrum coefficients that are inferred from the raw traffic by using Discrete Wavelet Transform(DWT). Experimental result shows that it has accurate identification results.关键词
