1. Electronic network apparatus for identifying media sessions over IP and network packets as belonging or not belonging to a media session, comprising:
- a packet characteristic extraction unit configured for obtaining traffic packet characteristics from a succession of packets, said packets respectively belonging to various unknown sessions;
a grouping unit associated with said packet characteristic extraction unit, configured to compare packets with other packets according to said extracted traffic characteristics to group together those packets whose extracted packet traffic characteristics are similar as probably belonging to a common session, anda session analyzer configured for analyzing said grouped packets for session characteristics, therewith to identify a session type of said probable common session.

15. A method of identifying session type, comprising
obtaining passing packets of respectively unknown sessions and unknown session types; -
obtaining traffic packet characteristics of said passing packets of respectively unknown session types; comparing said obtained packets with each other using respectively obtained traffic packet characteristics; grouping together those packets having similar values of said traffic packet characteristics into a presumed session; and analyzing said grouped packets of said presumed session for session characteristic; using said session characteristics to identify a session type of said presumed session. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)
