Speaker: Philippe Galvez

  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
