....unlikely. Instead, partnerships are usually formed among collaborating institutions. Research teams with members separated by substantial distance will be common in the future. High quality video conferencing is a promising means for such distributed scientific collaboration [Pea92, RV91, RG92, Sch96, YL94] Researchers from different institutions can have face to face conversation without traveling long distances. In addition to seeing the talking heads of the remote collaborators, the participants can exchange complex images with high resolution. Such images could include satellite images, ....

....scalable conferencing architecture. Dao et al. DSV 99] proposed a novel multicast method of efficient sharing during collaborative interactions among internetworked users. There has been extensive research conducted in the area of real time video transmission over the Internet [WHZ00, WHZ 01, Sch96] and a number of systems are proposed. A small number of commercial hardware based videoconferencing systems are available from Polycom Inc. Pol] and VBrick Systems Inc. VBr] The Polycom videoconferencing products are all based on the ITU H.323 model, and limited by the bandwidth constraints. ....

The latter being our focus, it is not clear to date where group coordination services should be deployed in the network protocol stack to fulfill these requirements, under the constraints of individual, group, system, and network behavior. Previous coordination protocols have been implemented at ....

Sarin and Greif discussed floor control for text based real time conferencing and point out a potential efficacy gain by employing multicasting [30] Schooler touches on floor control issues with regard to video and audio in surveying multimedia conferencing [31]. ITU standardization efforts on multipoint multimedia conferencing [38] are more geared towards circuit switched networks and do not include multicast provisions. In contrast to LAN oriented CMA, wide area conferencing tools for the MBone [14] are dominated by light weight session management ....

....server is used. Many designers of groupware focus on the distribution architecture when presenting their platforms. Unfortunately the terms defining a specific distribution architecture are extremely vague. The classical approach to describe distribution architectures (e.g. in [1] 4] 15] [26]) distinguishes between two types: In central architectures, the groupware application runs on a central server. This architectures often are called single site execution. In replicated architectures, the groupware application runs on each user s site (multi site execution) These ....

Fortunately, this development coincides with the great performance increase of the US research network so that communication, data sharing, and joint use of instrumentation and computing facilities can be realized on the necessary scale (Schooler, 1996; Kouzes et al. 1996; Shortliffe et al. 1996; Clutter, 1996; Finholt and Olson, 1997) The wide bandwidth network connects the structural biology community today to massively parallel powerful computers, pumping data back to their local site for immediate visualization (UCAID, 1997) An ....

....by sending an HTTP request. He or she can either join an existing group or create a new group. A group of collaboration lasts until the group is terminated by the system or when nobody has a desire to be the leader. In this subsection, we propose a simplified collaborative group definition (SCGD) [4] that is a simplified description of the syntax, or form, of individual statements. Table 1 shows a set of language specification, which is in the Backus Naur form, for the SCGD. The syntax provides a description for efficiently collaborative session in the system. Table 1. Simplified ....

....artifacts, without need to find and schedule common times. Asynchronous collaboration represents a less imposing form of collaboration over the schedule of geographically distributed participants. The notion of session and workspaces is central to synchronous computer supported collaborative work [92]. However, the notion has been absent so far from asynchronous computer supported collaborative work. Our replayable workspace paradigm couples the notions of a shared workspace (found in synchronous groupware, e.g. XTV [1, 17] TkReplay [25] DistView [83] SharedX [38] XMX XTRAP [49] etc. ....

Human audio communication plays a central role in a collaborative session because it is typically the stream that carries the critical component for group discussion [1].

We call all these operations group rendezvous. [Scho96] defines the rendezvous as the action of inviting other users or scanning for open sessions. This includes Email or WWW based systems. This kind of rendezvous has a long term character inviting someone via Email or posting a meeting date on a bulletin board is usually performed hours or days ....
