Subject: Protocol Action: 'RTP: A Transport Protocol for Real-Time
Applications' to Full Standard
The IESG has approved the following documents:
- 'RTP: A Transport Protocol for Real-Time Applications '
RFC 3550 as a Full Standard
- 'RTP Profile for Audio and Video Conferences with Minimal Control '
RFC 3551 as a Full Standard
These documents are products of the Audio/Video Transport Working Group.
The IESG contact persons are Allison Mankin and Jon Peterson.
Ballot Text
Technical Summary
RFC 3550 describes RTP, the real-time transport protocol. RTP
provides end-to-end network transport functions suitable for
applications transmitting real-time data, such as audio, video or
simulation data, over multicast or unicast network services. RTP
does not address resource reservation and does not guarantee
quality-of-service for real-time services. The data transport is
augmented by a control protocol (RTCP) to allow monitoring of the
data delivery in a manner scalable to large multicast networks, and
to provide minimal control and identification functionality. RTP and
RTCP are designed to be independent of the underlying transport
and network layers. The protocol supports the use of RTP-level
translators and mixers.
RFC 3551 describes the Audio-Video Profile of RTP, "RTP/AVP", providing
interpretations of generic fields within the RTP specification suitable for
audio and video conferences with minimal control. It defines a set of
default mappings from payload type numbers to encodings, pointers
to reference implementations and standards, and registrations of
mediatypes.
Working Group Summary
The Working Group whole-heartedly supported RTP's advancement
to Full Standard as soon as it had spent the minimum period in
Draft Standard.
Protocol Quality
RTP is a mature protocol. There are dozens of full implementations.
The implementation report for Draft Standard was assessed to be very
complete. The determination of RTP going to Full Standard was
evaluated by Allison Mankin for the IESG. There were several
messages for support for this in response to the IETF Last Call, and
no negative messages.
