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

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

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

  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
