Designing a Workstation-Based Conferencing System Using the Real-Time Producer/Consumer Paradigm
Abstract
One component of this project is the construction of a distributed, real time, video conferencing system on a network of high performance workstations. This note concerns the technological issues involved in realizing a workstation-based conferencing system. The emphasis of our research is on the development of operating system and network support for real-time communication of digital audio and video streams. From a technological standpoint, the goal is to support multiple, concurrent streams of digital audio and video in a distributed network of computer workstations. These streams may either form disjoint conferences within the network or involve one node (workstation) in multiple simultaneous conferences. Our approach is to view the problem as one of realtime resource allocation and control. This report is organized in the following sections. Section 2 describes the broader context of this work and motivates our use of computer workstations for a desk-top conferencing system. Section 3 describes the RTP/C paradigm in greater detail and discusses its application to the problem of supporting digital audio and video in a distributed system. Section 4 outlines both the hardware and software environment of the physical system that we are building. Sections 5 and 6 conclude this report with brief discussions of our long range goals, expected contributions and current status.
