Hi,

In 4566bis, <proto> defines a transport protocol.

In case of RTP, the text refers to RTP/AVP as an “RTP profile”, but it is still a transport protocol.

Christer

Subject: Re: [rtcweb] Results of call for consensus on ICE transport parameter issue

Found a way to address this with minor changes to the existing PR.

Roman, thanks for raising this. I looked into this a bit and it's kind of ambiguous; https://tools.ietf.org/html/rfc7850 uses "profile", "proto", and "protocol" (although "protocol" is used most frequently).

JSEP actually uses both profile and protocol to refer to the transport, depending on the section; if we make a change here, we should hit all usages, which probably means that it is outside of the scope of this particular issue.

Hi Justin,

I did provide editorial feedback to the change on github:

1. This document refers to SDP protocol as profile. If you look at the referenced documents that define "profiles" in JSEP, they all refer to them as protocols. Also, in case of SRTP, profile is actually something different and refers to SRTP key parameters.

2. Default candidate does not have profile (or protocol), it has transport, port, and (connection-)address. So each "m=" and "c=" MUST be filled in with port, protocol, and address to match port, transport, and address of the default candidate for the m= section, as described in ice-sip-sdp.

I have updated this PR to incorporate minor feedback that was received during the consensus call. Those who had feedback, please take another look and comment on the PR if you are satisfied.

The chairs believe that there was rough consensus among those responding to make the change in:

https://github.com/rtcweb-wg/jsep/pull/863

Given the state of the document, it will be the Area Director's call as to how much of the post-working group approval process must be re-done.  Authors, please wait on his direction before publishing a new version with this merged.

Ted and Sean
