....was vat [JMa] developed at the Lawrence Berkeley Laboratory (LBL) Nevot [Sch1] a tool similar to vat, was developed at INRIA, France. Video tools include Xerox PARC s nv [R94] INRIA s ivs [T94] and vic [MJ95] from LBL. Another novel tool for MBone conferencing is the electronic whiteboard, wb [JMb]. This tool has since evolved into mb [RT94] a mediaboard tool for investigating reliable multicast protocols. One common problem across these applications is the need for coordination between them. The video tool, vic, introduced the notion of a conference bus [MJ95] which is used for ....
....is built on top of the SRM toolkit [RT96] developed by researchers in the MASH research project at Berkeley. SRM is a protocol layer build on top of IP Multicast that provides reliability in a scalable manner. The protocol was developed out of an implementation of the shared whiteboard tool, wb [JMb]. SRM uses a receiver based NACK scheme to signal packet loss (instead of the traditional positive acknowledgment schemes used in reliable unicast) The sender or any other member can retransmit the data on receiving a NACK (or repair request, in SRM terminology) To achieve scalability, SRM uses ....

.... University of Ottawa Ottawa, Ontario, Canada K1N 6N5 Email: georgana mcrlab.uottawa.ca ABSTRACT With the recent rise of interest in multimedia applications, we have witnessed the emergence of more and more video conferencing systems such as Communique , the MBONE suite of tools (nv, vic, vat, wb)[1 3], Isabel[4] etc. These applications provide tools for video, audio and text information exchanging in the conference. They also provide a whiteboard for sharing images and drawings, etc. However, none of the existing applications we know provides a whiteboard for sharing continuous media in the ....
