Collaborative environments supporting point to point and
multipoint videoconferencing, document and application
sharing across both local and wide area networks, video
on demand (broadcast and playback) and interactive text
facilities will be a crucial element for the development
of the next generation of HEP experiments by geographically
dispersed collaborations.
The "Virtual Room Videoconferencing System" (VRVS) has been
developed since 1995, in order to provide a low cost,
bandwidth-efficient, extensible means for videoconferencing
and remote collaboration over networks within the High
Energy and Nuclear Physics communities.
The VRVS system is based on a Virtual Videoconference Room
concept. Since it went into production service in early
1997, deployment of the Web-based system has expanded to
include 1550 registered hosts running the VRVS software
from more than 30 different countries, and 22 "reflectors"
that manage the traffic flow, at HENP labs and universities
in the US and Europe. So far, there are 7 Virtual Rooms for World Wide Conferences (involving more
than one continent), and 4
Virtual Rooms each for intra-continental conferences in the US or Europe.
We review future and ongoing developments (VRVS extension,
MPEG1/2 integration, Shared environment, QoS over networks,
etc..), to support a set of new and essential requirements
for rapid data exchange, and a high level of interactivity
in large-scale scientific collaborations
