The method used to accurately classify P2P traffic remains a key problem for Internet Service Producers （ISPs） and network managers. This paper proposes a novel approach to the accurate classification of P2P traffic at a fine-grained level, which depends solely on the number of special flows during small time intervals. These special flows, named Clustering Flows （CFs）, are de- fined as the most frequent and steady flows generated by P2P applications. Hence we are able to classify P2P applications by detecting tlle appearance of corresponding CFs. Com- pared to existing approaches, our classifier can realise high classification accuracy by ex- ploiting only several generic properties of flows, instead of extracting sophisticated fea- tures from host behaviours or transport layer data. We validate our framework on a large set of P2P traffic traces using a Support Vector Machine （SVM）. Experimental results show that our approach correctly classifies P2P ap- plications with an average true positive rate of above 98% and a negligible false positive rate of about 0.01%.展开更多

The advent of the Internet age also become more virtual to business models, and now the development of enterprises has involved the application of e-commerce technology, the company＇ s business model combines network through electronic technology to some extent, and it made great adjustments and changes in order to deal with the new face of increasingly fierce competition in the market. Thus a new term： ＂E-commerce＂ is well known and accepted as more and more people. A regional economic development need of the residents＇ daily consumption is driven, so local governments need to focus on the various steady development of local small and medium enterprises.
