Abstract
Advances in network technology and research in real-time packet-switched networks have prompted the emergence of internet conferencing. While audio and video conferencing tools are readily available, shared workspaces and drawing tools have been slower to emerge. We present a design for a network conferencing whiteboard that differs in notable respects from other shared workspace prototypes. We describe its transport layer, based on IP multicasting and application level framing, and its object oriented imaging model, based on persistent PostScript graphics operations. We then propose a user interface, and finally, describe a C++ implementation based on the InterViews structured graphics library. 1 Introduction In the early days of the Internet, experiments with packet voice proved that computer networks could be used for integrated services [5]. However, the technological limitations of the time made such use impractical. This is now changing. Dramatic advances in network bandwidth an...
