VoIP traffic behavior profiling method

摘要

The invention relates to a method for profiling VoIP activity in network traffic. The method includes obtaining a plurality of audio packets from a plurality of packets in the network traffic by analyzing a plurality of parameter sets based on a first pre-determined criterion, wherein each of the plurality of parameter sets corresponds to a packet of the plurality of packets and comprises a packet size and a packet arrival time associated with a corresponding packet of the plurality of packets, generating a count of an IP address by counting at least a portion of the plurality of audio packets, wherein each packet of the portion of the plurality of audio packets comprises the IP address, and identifying an endpoint corresponding to the IP address as a VoIP server and identifying the portion of the plurality of audio packets as VoIP activity associated with the VoIP server when the count exceeds a pre-determined threshold.
