Abstract
Some characteristics of network application flow are inconspicuous,and they can not be simply identified by Keywords,ports+IP.The paper applies fuzzy mathematics theory to P2P traffic identification,and presents a kind of Fuzzy Recognition Method based on Flow Characteristic Description(FCD).FCD fuzzy recognition method analyzes captured network data first,and then describes uniformly key processes.Subsequently,the paper analyzes distributional state of those data in key process,and obtains their membership functions,which can be used as comment aggregates.Finally,fuzzy judgment method will judge whether the data are some kind of network application.The proposed recognition method is put to test through a popular network game.The experiment results verify that FCD fuzzy recognition method can identify network game flow and its accuracy is high.
