Videoconferencing at UVa
Video conferencing applications can be classified according to a matrix of network type and number of participants. The network types are primarily LAN (Local Area Network, i.e., Internet connectivity) and ISDN (phone system); the participant number is person-to-person or group. Often the determination of whether to videoconference with a remote site must be based on whether that site uses H.323 (LAN) or not. ISDN is still very prevalent at commercial sites and even in some educational sites.
While desktop video conferencing itself may not be sufficiently mature to warrant investment of large amounts of resources for wide deployment, desktop collaboration is evolving as a valuable tool for the workplace. Desktop video still may be very appropriate in some cases. A person who is considering use of desktop videoconferencing needs to be aware of the current shortfalls imposed by network bandwidth restrictions and the impact of other network usage. In general, a site that uses Internet 2 will not experience the same network congestion as a site on the commercial Internet. This is an area that is continuing to evolve. Early adopters may gain valuable experience, but also may need to make equipment and hardware upgrades regularly to take advantage of advances in the field.
