CERN is the European Organization for Nuclear Research, the world's largest particle physics centre. Founded in 1954, the laboratory was one of Europe's first joint ventures, and has become an outstanding example of international collaboration. From the original 12 signatories of the CERN convention, membership has grown to the present 20 Member States. CERN explores what matter is made of, and what forces hold it together. The Laboratory provides state-of-the-art scientific facilities for researchers to use. These are accelerators that accelerate tiny particles to a fraction under the speed of light, and detectors to make the particles visible. To accomplish its mission, CERN relies on advanced information technology and has become well known world-wide for its IT technology innovations, including those related to the Internet. For example, CERN is where the Web was initially created.

DiffServ Demonstration:
Olivier Martin, Paolo Moroni, Joop Joosten are involved in a wide variety of projects involving advanced network support for high performance computing, large-scale storage of massive data volumes generated by High Energy Physics, mining very large databases, scientific visualization and Internet media. Recently, they have been involved in DiffServ experimentation, including the development with iCAIR of a trans-Atlantic DiffServ testbed for Internet media.

Philippe Galvez is one member of the (high-energy physics research) team responsible for the management of high-speed transatlantic network. He manages the international web-based videoconferencing system known as VRVS (Virtual Rooms Videoconferencing System), which he created in 1996 (see at http://www.vrvs.org) and which allow thousands of scientists to collaborate world wide. These developments have led to his assignment as project leader and chief developer for these new forms of videoconferencing at Caltech and CERN in Geneva. The VRVS, presented as part of the iGRID GiDVN demonstration, demonstrates an example of a particularly innovative Internet service. The VRVS provides a low cost, bandwidth-efficient, extensible tool for videoconferencing and collaborative work over networks within the High Energy and Nuclear Physics communities and to some extent within research and education at large. The VRVS system presents an excellent example of an efficient, scalable facility and service that is accessible to communities throughout the world. Philippe is responsible for World Wide VRVS coordination, maintaining the VRVS reflectors distribution all over the world (Europe, Asia, America), and elaborating (in collaboration with its colleagues) future developments which includes integration of MPEG2, H.323 technology as well as next generation collaborative tools to the current VRVS system.
