|With the success of the Internet and exibility of MPEG-4, transporting MPEG-4 video over the Internet is expected to be an important component of many multimedia applications in the near future. Video applications typically have delay and loss requirements, which cannot be adequately supported by the current Internet. Thus, it is a challenging problem to design an e cient MPEG4 video delivery ...

This document specifies an extension to the Real-time Transport Control Protocol (RTCP) to use unicast feedback to a multicast sender. The proposed extension is useful for single-source multicast sessions such as Source-Specific Multicast (SSM) communication where the traditional model of many-to-many group communication is either not available or not desired. In addition, it can be applied to ...

The RTP Control Protocol (RTCP) is used in conjunction with the Realtime Transport Protocol (RTP) in order to provide a variety of shortterm and long-term reception statistics. The available reporting may include aggregate information across longer periods of time as well as individual packet reporting. This document specifies a per-packet report metric capturing individual packets discarded fr...

This document describes the results achieved when simulating the timing rules of the Extended RTP Profile for Real-time Transport Control Protocol (RTCP)-Based Feedback, denoted AVPF. Unicast and multicast topologies are considered as well as several protocol and environment configurations. The results show that the timing rules result in better performance regarding feedback delay and still pr...

In this paper new, lightweight security and control protocol for Voice over Internet Protocol (VoIP) service is presented. It is the alternative for the IETF’s (Internet Engineering Task Force) RTCP (Real-Time Control Protocol) for real-time application’s traffic. Additionally this solution offers authentication and integrity of voice send and it is capable of exchanging and verifying QoS and s...
