1. ViDeNet Addressing Challenges in Global Addressing for Video and Voice Over IP

2. What is ViDeNet? A Global Video and Voice Over IP virtual network A testbed for global video and voice over IP Evolving Dial Plan Knowledge-Sharing Community Zone Management Tool Development Directory Development

3. Numeric Dial Plan History Version 1.0: Full Mesh Expanded IP address + * Example: 152002002199* Did not work with IP phones Did not work with Cisco Version 2.0: Full Mesh Derived from gatekeeper IP address Added support for Cisco MCM Added support for IP phones Dynamic Length

4. Version 3.0 Goals Redundant Master Gatekeeper No longer a need for zones to maintain full mesh neighbor tables Point to a short list of static master gatekeepers Environment conducive to architectural exploration Support for E.164 namespace Support for gatekeeper hierarchies Support non-E.164 namespace (Super Space) Support single-level hierarchies

5. Version 3.0 Numeric Architecture 353 Ireland 21 Cork 1 Dublin 91 Galway 972 Israel 1919962 Carolina 1614292 Ohio State 09 Public 019 Zone A 029 Zone B 039 Zone C 049 Zone D 00 Root 00 Root 00 Root Redundant RADVision ECS Distributed worldwide Via LRQ hunting Super Space (0+) E.164int Space (1-9+) *No Country GK *Hierarchies possible though not likely Super Space uses 0 reserved country code To allow escape from E.164 space LDAP Zone Repository

6. E.164int Hierarchies Pros Emulates telephone network Geographically oriented Well known numbering scheme Cons Namespace owned by PSTN operators Geographically oriented Many points of failure Closed set

7. Super Space Pros Not geographically bound Short prefix Namespace not regulated Few points of failure Cons E.164 escape requires special config Not scalable to millions

8. New ViDeNet Web Environment Tools to manage your zone Publish customized dialing instructions Publish your resources (MCU, gateway, etc.) Publish Contact Information Directory-Oriented Personalized Zone Managers can manage user directories Public Directory Expanded MCU resources around the world
