A new Request for Comments is now available in online RFC libraries. RFC 1889: Title: RTP: A Transport Protocol for Real-Time Applications Author: Audio-Video Transport Working Group, H. Schulzrinne, S. Casner, R. Frederick & V. Jacobson Date: January 1996 Mailbox: schulzrinne@fokus.gmd.de, casner@precept.com, frederic@parc.xerox.com, van@ee.lbl.gov Pages: 75 Characters: 188,544 Updates/Obsoletes: none URL: ftp://ds.internic.net/rfc/rfc1889.txt This memo 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. This RFC is the product of the Audio/Video Transport Working Group of the IETF. This is now a Proposed Standard Protocol. This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
