TL;DR: RTP provides end-to-end network transport functions suitable for applications transmitting real-time data over multicast or unicast network services and is augmented by a control protocol (RTCP) to allow monitoring of the data delivery in a manner scalable to large multicast networks.
Abstract: This memorandum 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.

TL;DR: This experiment was not only the first sizeabl e audio muldcast over apacket network, but also significan t for the size of the IP multicast network topology itself.
Abstract: At the March, 1992 meeting of the Internet Engineerin g Task Force (IETF) in San Diego, live audio from severa l sessions of the meeting was "audiocast" using multicas t packet transmission from the IETF site over the Internet t o participants at 20 sites on three continents spanning 1 6 time zones . This experiment was not only the first sizeabl e audio muldcast over apacket network . but also significan t for the size of the IP multicast network topology itself .

15 Oct 2003TL;DR: In this paper, an IP Multimedia Subsystem (IMS) proxy adjunct is implemented to make extensions to messages according to any protocol providing a session description protocol (SDP) component, such as SIP or RTSP, so as to ensure the selected QoS.
Abstract: A user equipment (UE) device (11) including a mobile terminal (MT) (11b 11b') coupled to a terminal equipment (TE) device (11a) including an IP Multimedia Subsystem (IMS) proxy adjunct (P+) for use by the TE (11a) in making multimedia service requests for IP communications with a desired end-to-end QoS, the end-to-end including the local connection and a network supporting QoS, e.g. an UMTS network (12) having as an extension of its packet-switched core network (12b) an IMS (12c) providing multimedia services with selected QoS. The IMS proxy adjunct (P+) is implemented to make extensions to messages according to any protocol providing a session description protocol (SDP) component, such as SIP or RTSP, so as to ensure the selected QoS. In addition, a mechanism is provided by which the MT (11b') informs the IMS (12c) when it has IMS proxy capabilities.
