摘要
Desktop conferencing and distributed graphical editing applications allow people to perform cooperative work regardless of their geographic location. One such example is the CoDraft application presented here. This collaborative system allows concurrent sketching on a shared drawing board. The current version is implemented on top of point-to-point communication services. It is shown that these services are not well suited for cooperative applications. Therefore, a multiparty communication platform is proposed that manages groups of application instances and multicast messages, handles group voting and transfers files to more than one target site at a time. This platform greatly simplifies the development of cooperative applications. Additionally, the platform allows the lower-level multicast functionality to be more fully exploited, thus improving response time and throughput performance.
