The RTCP gateway: scaling real-time control bandwidth for wireless networks
In this paper, we identify the deficiencies of Real-Time Protocol (RTP) scaling when deployed in low-bandwidth or wireless networks. As RTP is used to support audio and video communication over the Internet, scalability over a wide bandwidth range is important to its continued acceptance. We describe the design and implementation of a real-time control protocol (RTCP) gateway which provides the scaling functions necessary to allow wireless participants to engage in high-bandwidth conferencing sessions. RTCP gateway functionality is compatible with the most commonly used data scaling strategies and does not affect RTP functions on the fixed network. (C) 2000 Elsevier Science B.V.
