2. 2 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

3. 3 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

4. 4 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

18. 18 Global Dialing Scheme

19. 19 GDS  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

20. 20 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

21. 21 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)
