A new IETF working group has been proposed in the Real-Time Applications and Infrastructure Area. The IESG has not made any determination as yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg@ietf.org) by Tuesday, January 18, 2011. Audio/Video Transport Core Maintenence (avtcore) ------------------------------------------- Current Status: Proposed Working Group Last modified: 2010-12-03 Chairs: TBD Real-Time Applications and Infrastructure Area Directors: Gonzalo Camarillo <gonzalo.camarillo@ericsson.com> Robert Sparks <rjsparks@nostrum.com> Real-Time Applications and Infrastructure Area Advisor: Robert Sparks <rjsparks@nostrum.com> Mailing Lists: TBD Description of Working Group: The Real-time Transport Protocol, RTP, along with its associated profiles and payload formats provides for real-time transmission of audio and video over unicast and multicast transports. RTP itself has been shepherded to Full Standard. Its associated profiles, extensions, and payload formats are currently at various levels of standards maturity. The AVTCORE working group is chartered to maintain the core RTP/RTCP protocols and the AVP, SAVP, AVPF, and SAVPF profiles. The group will provide architectural guidance for extending the protocols and guidelines for their proper use. While other working groups may be chartered to work on application-specific extensions to the protocols, extensions that are generally applicable will be developed in AVTCORE. The AVTCORE working group will coordinate closely with the Security Area while working on maintenance and enhancements to the SRTP Profile. In addition to the milestones called out below, the AVTCORE working group's initial tasks will include completing any remaining work identified in those drafts from the AVT working group already in IESG Evaluation, with the exception of the Rapid Acquisition of Multicast RTP sessions, which will complete in the AVTEXT working group. Goals and Milestones: Dec 2010 Submit Guideline for Choosing RTCP CNAME as Proposed Standard Dec 2010 Submit use of AES-192 and AES-256 in Secure RTP for Proposed Standard Dec 2010 Submit Port Mapping Between Unicast and Multicast RTP Sessions for Proposed Standard Dec 2010 Submit Real-Time Transport Control Protocol (RTCP) in Overlay Multicast for Proposed Standard Feb 2011 Submit Monitoring Architecture for RTP for Informational Feb 2011 Guidelines for the use of Variable Bit Rate Audio with Secure RTP as informational (or possibly BCP) Apr 2011 Submit in band keying mechanism for SRTP draft for Proposed Standard Apr 2011 Submit Explicit Congestion Notification (ECN) for RTP over UDP for Proposed Standard May 2011 RTCP indication for retransmission suppression as proposed standard Sep 2011 Encryption of Header Extensions in the Secure Real-Time Transport Protocol (SRTP) for Proposed Standard _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
