Tim Poe University of North Carolina ViDeNet and theGlobal Dialing Scheme Internet2 Commons Site Coordinator Training December 3, 2003 National University of Singapore
Video Development Initiative • Video Development Initiative (ViDe) • Founded by representatives from universities and education networks • Interests include deploying scalable, standards-based digital video architecture and services for use in research and higher education • Co-sponsors workshops and digital video projects with the Southeastern Universities Research Association, Internet2, the Coalition for Networked Information, and leading industry consortia
ViDeNet • ViDeNet • A ViDe Project • A global, virtual network providing video and voice-over-IP to advanced networking communities • An architecture that has been adopted for use by the Internet2 Commons • An exploration of directory services for videoconferencing through ViDe's participation in the Internet2 VidMid program
Benefits of ViDeNet • Use of the Global Dialing Scheme • A searchable directory • User-managed accounts • Zone management tools for creating a customized portal • A zone administrator listserv • Developing initiatives such as emergency communications
A structure for peering between gatekeepers, such that any endpoint associated with a ViDeNet zone may dial an endpoint in any other ViDeNet zone ViDeNet Version 3 Dial Plan A numbering plan for global video and voice over IP GDS
GDS Number Scheme • Each number has four parts • International Access Code (IAC) (also called the world gatekeeper prefix)- defined as 00 • A Country Code (CC)- follows the ITU international access code system (1 for the US • An Organizational Prefix (OP)- ViDeNet assigned them; some countries use area code/exchange prefix • An Endpoint Number (EN)- a unique number (sometimes called H.323 extension) assigned to each endpoint by each organization (could be a E164 number or any other unique number) • IAC CC OP EN
GDS at Northwestern • The IAC is “00” • For the EN, we use a “1” followed by the last five digits of your telephone number • If you have more than one Video station and only one telephone number, follow the six digits by an integer • Northwestern was assigned 1169 as a organizational prefix • The number of my telephone on my desk at Northwestern is 847 467 6885 and the GDS dial number of my Viewstation is thus: 00 1 1169 176885 (spaces for readability only) • Northwestern users registered with the Northwestern gatekeeper can use a short cut and dial each other using only the EN (176885 for me)
