Re: [IPFIX] RTP media stream template?

Hey Hendrik,
Argus has RTP specific flow records, with its own IEs for reporting attributes
and metrics for the media streams.   The argus sensor does RTP discovery
on the fly, generating the extended flow attributes without configuration.

The argus DSRs provide the RTP specific information, such as codec, as
well as jitter, ( adjusting for silence suppression when encountered ), loss
and out of order indications, and the argus-client aggregation deals with
handling both entire streams and fixed/variable time slices, no problem.

Argus is not IPFIX, but you may find the argus approach useful.
