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

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

4
ViDeNet Zones

• International
• Universities
• Educational institutes
• Research institutes
• Research and Educational Networks
• Companies
• Public Zone

189 Zones (05-2004) ! 10000 endpoints And
counting

Detailed tool description

• 1. Any user can put themself in the directory and
  manage their own information. They can give their
  endpoints friendly names.
• 2. Zone administrators can create as many zones
  as they need for themselves.
• 3. Zone administrators can use the ViDeNet tool
  to manage
• a. custom web portal for their zone (demo UNC
  zone for fun)
• b. scratch pad for important info
• c. routing (i.e. peering into GDS)
• d. research other zones and zone admins
• e. listserv for sharing information
• f. add commObject data (i.e. h.323 address) to
  users.
• g. review/approve/delete user requests
• 4. Users may search the H.350 directory.

• Global Dialing Scheme

9
GDS

• A numbering plan for global video and voice over
  IP
• A structure for peering between gatekeepers, such
  that any endpoint associated with a ViDeNet zone
  may dial an endpoint in any other ViDeNet zone

10
Global Dialing Scheme

• Principles
• International, but Freedom of choice for local
  situation
• E.164/tel.no. integration
• Implemented by present gatekeeper technology
• Compatible with existing network (ViDeNet)
• Governed by ViDes Numerical Address Space
  Management (NASM) working group
• Proposal
• by SURFnet, UKERNA, HEAnet, UNC
• Implemented by ViDeNet, Internet2 and NREN
  services and testbeds

11
Numerical Address Space Management (NASM)

• Core Dial Plan Management for ViDeNet
• Manage Root Gatekeeper Hierarchy
• ViDeNet admissions
• Root ViDeNet tool administration

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)
