The large number of applications and their use of dynamic sessions cause one of the main problems with traffic analysis in the recent Internet. The traditional wellknown port number based traffic analysis mechanism is not sufficient to analyze newly emerging Internet traffic, such as P2P, streaming media, and game traffic. And more sophisticated high precision traffic measurement is required for control of current Internet traffic. In this paper, we propose mechanisms based on signature-mapping and subgroup to cope with the challenges and presented the system architecture.
