ViDeNet Addressing
Challenges in Global Addressing for
Video and Voice Over IP
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
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
Version 3.0 Numeric Architecture

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
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
