Brief Description of the Collaboratory :

 

The Access Grid is an ensemble of resources and technology which provides a virtual collaboration tool. The Access Grid is an Internet-based model for video conferencing that focuses on group-to-group communication, using an ensemble of resources including multimedia large-format displays, presentation and interactive environments, and interfaces to Grid middleware and visualization environments. An Access Grid can be used as an advanced type of videoconferencing facility that allows participants from multiple locations on the Internet to interact in real time. The Access Grid is more than videoconferencing, as it provides mechanisms to share data, collaborate using a variety of shared applications (such as sharing presentation material), utilize large-format displays and can employ multiple video sources to allow room -to -room conferencing capabilities. The technology was invented at Argonne National Laboratory, Chicago, United States of America.

The Access Grid software is free and open source. Core components include the Robust Audio Tool (RAT), an open-source audio conferencing and streaming application, developed by the University College London; ViC, the Video Conferencing tool developed by the Network Working Group at Lawrence Berkeley National Laboratory in collaboration with the University of California, Berkeley; and the Access Grid Venue Client which also includes a Extensible Messaging and Presence Protocol, specified in RFC 3920 and RFC 3921 are Draft Standard within the Internet Standards Process.

Access Grid is an implementation of the application-layer, Real-time Transport Protocol for defining standard packet format for delivering audio and video over the Internet. It was developed by the Audio-Video Transport Working Group of the Internet Engineering Task Force and first published in 1996 as RFC 1889, and superseded by RFC 3550 in 2003.
There are 287 registered Access Grid nodes listed, across 28 different countries across the globe with over 500 total nodes estimated in 2005. There is a high concentration of nodes in Australia, the United States, Canada, and Europe.

 
 

Access to Instruments :

  AccessGrid is a software product, which is freely downloadable. In addition to an appropriate computer system and network connectivity, hardware for the access grid consists of three core components; video, audio and display. This can be as simple as a laptop with a web camera and a headset using the screen as a display unit, or as sophisticated as a specially built room with multiple cameras, projectors and a separation of services on multiple machines for video producter, consumer and audio.  
 

Access to Information Resources :

  AccessGrid users can connect with other AccessGrid users to collaborate and share information.  
 

Access to People as Resources :

  AccessGrid users can connect with other AccessGrid users to collaborate and share information.
