I'm personally quite satisfied with its current stage, and only have a few comments and nits on it. Section 3.1 anticipates what is explained in better detail in the following subsections. Anyway, credentials are not mentioned there, e.g., when introducing passthrough mode. Although the management of all ICE semantics, including credentials, is addressed in the related subsection, I'd make this explicit in the intro as well, as it only talks about forwarding candidates and may confuse the reader. Typo in Section 4: s/dont/don't I'd personally swap Sections 3 and 4, in order to first address signalling-only B2BUAs and only then move to media-aware and media-terminator: this would be more consistent with how the taxonomy is referenced in the document, in Section 2.

Subject: [straw] Suggestion for WG = adoption: draft-ram-straw-b2bua-dtls-srtp-02

(As co-chair)

 

Hi,

 

The chairs would like to suggest that draft-ram-stra= w-b2bua-dtls-srtp-02 is adopted as base for the following delivery:

 

=93A document defining the requirements for B2BUAs t= o support DTLS-SRTP (RFC 5764) end-to-end submitted to the IESG as PS=94

 

If you have any issues with adopting the draft, or i= f you intend to submit a draft of your own for the delivery, please indicat= e so on the list by Friday 13th.

 

Regards,

 

Christer & Victor

This draft is a work item of the Sip Traversal Required for Applications to Work Working Group of the IETF. Title : Session Traversal Utilities for NAT (STUN) Message Handling for Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) Authors : Ram Mohan Ravindranath Tirumaleswar Reddy Gonzalo Salgueiro Filename : draft-ietf-straw-b2bua-stun-03.txt Pages : 14 Date : 2015-03-04 Abstract: Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) are often designed to be on the media path, rather than just intercepting signaling. This means that B2BUAs often act on the media path leading to separate media legs that the B2BUA correlates and bridges together. When acting on the media path, B2BUAs are likely to receive Session Traversal Utilities for NAT (STUN) packets as part of Interactive Connectivity Establishment (ICE) processing. It is critical that B2BUAs handle these STUN messages properly. This document defines behavior for a B2BUA performing ICE processing. The goal of this draft is to ensure that ICE used for NAT and Firewall traversal of multimedia sessions works when there are B2BUAs in place and the B2BUAs handle STUN messages properly. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-straw-b2bua-stun/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-straw-b2bua-stun-03 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-straw-b2bua-stun-03 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Hi Charles,

I reviewed this and the previous version of the draft, providing mostly edi= torial comments privately to the authors at that time. I support its adopti= on as a working group draft. 

I have a couple minor comments on the current version that can be addressed= after adoption.

Sections  3.2.1 and 3.2.2 both start with =93This section describes me= dia-aware B2BUAs that =85=94, which leads me to expect multiple subsections= detailing everything I need to know about such a beast. The brevity of eac= h section is refreshing, but leaves me thinking there is a laundry list of addition items that needs to be added later. If= this is the case, add an editors note indicating that, else remove the mis= leading intro from each section. 

E.g.
3.2.1. Header inspection

   A media-aware B2BUA tha= t inspects but does not modify RTP headers does not terminate the DTLS-SRTP.

Section 3.2.1
s/B2BUAs that does not/B2BUAs that do not
Section 3.2.2
s/B2BUAs that modifies/B2BUAs that modify

Cheers,
Charles

This draft is a work item of the Sip Traversal Required for Applications to Work Working Group of the IETF. Title : Session Traversal Utilities for NAT (STUN) Message Handling for Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) Authors : Ram Mohan Ravindranath Tirumaleswar Reddy Gonzalo Salgueiro Filename : draft-ietf-straw-b2bua-stun-04.txt Pages : 14 Date : 2015-03-09 Abstract: Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) are often designed to be on the media path, rather than just intercepting signaling. This means that B2BUAs often act on the media path leading to separate media legs that the B2BUA correlates and bridges together. When acting on the media path, B2BUAs are likely to receive Session Traversal Utilities for NAT (STUN) packets as part of Interactive Connectivity Establishment (ICE) processing. It is critical that B2BUAs handle these STUN messages properly. This document defines behavior for a B2BUA performing ICE processing. The goal of this draft is to ensure that ICE used for NAT and Firewall traversal of multimedia sessions works when there are B2BUAs in place and the B2BUAs handle STUN messages properly. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-straw-b2bua-stun/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-straw-b2bua-stun-04 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-straw-b2bua-stun-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

This draft is a work item of the Sip Traversal Required for Applications to Work Working Group of the IETF. Title : Guidelines to support RTCP end-to-end in Back-to-Back User Agents (B2BUAs) Authors : Lorenzo Miniero Sergio Garcia Murillo Victor Pascual Filename : draft-ietf-straw-b2bua-rtcp-04.txt Pages : 16 Date : 2015-03-09 Abstract: SIP Back-to-Back User Agents (B2BUAs) are often envisaged to also be on the media path, rather than just intercepting signalling. This means that B2BUAs often implement an RTP/RTCP stack as well, whether to act as media transcoders or to just passthrough the media themselves, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, though, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP packets get lost because of mismatches in the reported data. This document defines the proper behaviour B2BUAs should follow when also acting on the signalling/media plane in order to preserve the end-to-end functionality of RTCP. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-straw-b2bua-rtcp/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-straw-b2bua-rtcp-04 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-straw-b2bua-rtcp-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Name: draft-ietf-straw-b2bua-rtcp Revision: 04 Title: Guidelines to support RTCP end-to-end in Back-to-Back User Agents (B2BUAs) Document date: 2015-03-09 Group: straw Pages: 16 URL: http://www.ietf.org/internet-drafts/draft-ietf-straw-b2bua-rtcp-04.txt Status: https://datatracker.ietf.org/doc/draft-ietf-straw-b2bua-rtcp/ Htmlized: http://tools.ietf.org/html/draft-ietf-straw-b2bua-rtcp-04 Diff: http://www.ietf.org/rfcdiff?url2=draft-ietf-straw-b2bua-rtcp-04 Abstract: SIP Back-to-Back User Agents (B2BUAs) are often envisaged to also be on the media path, rather than just intercepting signalling. This means that B2BUAs often implement an RTP/RTCP stack as well, whether to act as media transcoders or to just passthrough the media themselves, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, though, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP packets get lost because of mismatches in the reported data. This document defines the proper behaviour B2BUAs should follow when also acting on the signalling/media plane in order to preserve the end-to-end functionality of RTCP. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

Title : DTLS-SRTP Handling in Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) Authors : Ram Mohan Ravindranath Tirumaleswar Reddy Gonzalo Salgueiro Victor Pascual Parthasarathi Ravindran Filename : draft-ietf-straw-b2bua-dtls-srtp-00.txt Pages : 9 Date : 2015-03-23 Abstract: Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) often function on the media plane, rather than just on the signaling path.

17:23:46 -0000 A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Sip Traversal Required for Applications to Work Working Group of the IETF. Title : Guidelines to support RTCP end-to-end in Back-to-Back User Agents (B2BUAs) Authors : Lorenzo Miniero Sergio Garcia Murillo Victor Pascual Filename : draft-ietf-straw-b2bua-rtcp-05.txt Pages : 16 Date : 2015-03-24 Abstract: SIP Back-to-Back User Agents (B2BUAs) are often envisaged to also be on the media path, rather than just intercepting signalling. This means that B2BUAs often implement an RTP/RTCP stack as well, whether to act as media transcoders or to just passthrough the media themselves, thus leading to separate multimedia sessions that the B2BUA correlates and bridges together. If not disciplined, though, this behaviour can severely impact the communication experience, especially when statistics and feedback information contained in RTCP packets get lost because of mismatches in the reported data. This document defines the proper behaviour B2BUAs should follow when also acting on the signalling/media plane in order to preserve the end-to-end functionality of RTCP.
