ViDeNet Addressing

Challenges in Global Addressing for Video and Voice Over IP


What is videnet
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

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


Version 3 0 goals
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

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

E.164int Hierarchies


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

Super Space

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
