Hi Christer,

I reviewed the new text

 

I have a comment and a nit

 

Comment:  I am not sure what this sentence means "and the answerer MUST NOT
multiplex RTP and RTCP packets on a single port"

The answerer cannot send multiplex RTP and RTCP packets if the attribute is
not there, it can either send RTCP to RTP port+1 or to the port specified by
the a=rtcp attribute.

 

Nit: "the rules in Section 4" add of RFC5761

 

Roni

Hi,

 

I've submitted a new draft: draft-holmberg-avtcore-5761-update-00.

 

The draft clarifies that the a=rtcp-mux attribute is only allowed in an
answer if also present in the associated offer, and that the usage of
RTP/RTCP-mux is negotiated for both directions.

 

The need for this came from 3GPP, where people had different understandings
regarding the meaning of the current text.

 

For the GitHub fans: https://github.com/cdh4u/draft-5761-update (NOTE:
Personal repo)

 

Regards,

 

Christer
