Abstract

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.
