SIP: Session Initiation Protocol
14 The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for creating, 15 modifying, and terminating sessions with one or more participants. These sessionsExpand
RTP: A Transport Protocol for Real-Time Applications
TLDR
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. Expand
Real Time Streaming Protocol (RTSP)
TLDR
The Real Time Streaming Protocol, or RTSP, is an application-level protocol for control over the delivery of data with real-time properties that is intended to control multiple data delivery sessions, provide a means for choosing delivery channels such as UDP, multicast UDP and TCP, and provide a mean for choosing Delivery mechanisms based upon RTP (RFC 1889).

An Analysis of the Skype Peer-to-Peer Internet Telephony Protocol
TLDR
This paper analyzes key Skype functions such as login, NAT and firewall traversal, call establishment, media transfer, codecs, and conferencing under three different network setups. Expand
Application-layer mobility using SIP
TLDR
How the Session Initiation Protocol (SIP) can help provide terminal, personal, session and service mobility to applications ranging from Internet telephony to presence and instant messaging is described. Expand
Adaptive playout mechanisms for packetized audio applications in wide-area networks
TLDR
The authors investigate the performance of four different algorithms for adaptively adjusting the playout delay of audio packets in an interactive packet-audio terminal application, and indicate that an adaptive algorithm which explicitly adjusts to the sharp, spike-like increases in packet delay can achieve a lower rate of lost packets. Expand
RTP Profile for Audio and Video Conferences with Minimal Control
This document describes a profile called "RTP/AVP" for the use of the real-time transport protocol (RTP), version 2, and the associated control protocol, RTCP, within audio and video multiparticipantExpand
Mobility support using SIP
TLDR
This paper proposes to use mobility support in the application layer protocol SIP where applicable, in order to support real-time communication in a more efficient way. Expand
An Offer/Answer Model with Session Description Protocol (SDP)
This document defines a mechanism by which two entities can make use of the Session Description Protocol (SDP) to arrive at a common view of a multimedia session between them. In the model, oneExpand
Peer-to-peer internet telephony using SIP
TLDR
This work proposes a pure P2P architecture for the Session Initiation Protocol (SIP)-based IP telephony systems and supports basic user registration and call setup as well as advanced services such as offline message delivery, voice/video mails and multi-party conferencing. Expand
