Does RFC 6544 work (http://tools.ietf.org/html/rfc6544) for a normative reference on SRTP/AVP over TCP?

Hi Harald,



Could you please let me know the specification which indicates SRTP/AVPF/TCP

profile in Sec 2.2 of draft-ietf-rtcweb-transports-01.



Thanks

Partha


That's a good question!

http://tools.ietf.org/html/rfc4571 defines TCP/RTP/AVP, but there doesn't seem to be a corresponding defintion for SRTP/AVPF over TCP.

Neither is the RFC 4571 profile registered at IANA - I think both that and the DTLS forms should have been at http://www.iana.org/assignments/rtp-parameters/rtp-parameters.xhtml#rtp-parameters-7 - but this registry seems so short, I wonder if I'm missing something.
