Peering H.323 Networks for Voice and Video CollaborationAPAN 2004 GDS Dial scheme International Root H.323 Gatekeepers “ViDe.Net” and “Internet2 Commons” APAN Cairn 2004 July 2004
INTRODUCTION • Lots of people use H.323 world wide to collaborate, H.323 is a popular Voice and Video protocol. • Many Institutions use Gatekeepers for the basic Routing and glue within an institution. PROBLEM: How to bind Institutions together ANSWER: Simple Directory Gatekeepers!
Example: A User's PERSPECTIVE TODAY PROBLEM: • How to make a call to someone else? • How to participate in another organisations meeting. ANSWER: • Dial an IP Address, or 192.94.63.128 • Re-configure end point to register with some else’s Gatekeeper, then dial a number, eg 61262223575, then reconfigure it back when finished. RESULT: • More faults • Harder to use – thus gets used less • No peering for cheap calls.
Example: A User's PERSPECTIVE PROBLEM: • How to make a call to someone else? • How to participate in another organisations meeting. ANSWER: • Dial an IP Address, or 192.94.63.128 • Dial a number, eg 61262223575 • Dial an h323 alias, eg stephen.kingham@aarnet.edu.au RESULT: • Easy to use. • World wide coordination of support services. • Voice and Video calls.
HOW? • Have A Directory Gatekeeper per country to bind Institutions within a Country together. • The run several International Gatekeepers to bind all the Country Gatekeepers together. • Use a common dial-plan And it already exists! Global Dialling Scheme (GDS) • 4 duplicated International Directory Gatekeepers • 27 Country Gatekeepers • 156 advance voice and video networks • A community of Higher Education, some industry, K-12 and Research Organisations.
WHO RUNS “GDS” GDS – Global Dialling Scheme • Institutions run their own Gatekeeper, some share Gatekeepers. • A volunteer Institution provides the Country Directory Gatekeeper. Some Countries share Gatekeepers. • Volunteer Institutions run the International Directory Gatekeepers coordinated by the NASM Team. Numerical Addressing Space Management Team (NASM) • About NASM http://www.vide.net/workgroups/nasm/index.shtml • NASM Resources page http://www.vide.net/workgroups/nasm/resources.shtml • Consists of representatives from UKERNA (Wales), HEAnet (Ireland) SURFnet (Netherlands), UNC and Internet2-Commons (USA), and AARNet (Australia).
How NASM is split up The NASM are split up to support the different world time zones:
H.323 Gatekeeper hierarchy Based on ITU H.323 standards
What each Country needs to do • Someone has to volunteer to provide a National Directory Gatekeeper per Country. Some Countries share gatekeepers. • Someone in each Country has to volunteer as the Administrator/Coordinator. • That Administrator needs • to Create and Register the Country Zone, and • authorise Zone requests from Institutions within their Country and enter them into the gatekeeper. The ViDeNet web site provides the administrative support.
What each Institution needs to do • Someone has to volunteer to provide a National Directory Gatekeeper per Country. Some Institutions share Gatekeepers – just about all the Australian Universities use one gatekeeper. • That Administrator needs to Create and Register the Institutions Zone. The ViDeNet web site provides the administrative support.
HOW TO PEER YOUR COUNTRY/ORGANISATION TO THIS NETWORK • The detailed steps can be found here: http://www.aarnet.edu.au/engineering/projects/voip/gds/ • You need at least one (or more) individual to be the Administrator. • That individual uses the ViDeNet web site to create their individual account. • The Administrator then uses the ViDeNet web site to request a Zone. • The NASM group manually process International Requests and advise the Administrator. The Country Administrator processes requests from Institutions from within the Country. • NASM update the International Directory Gatekeepers with any new Countries; The Country Administrator configures their National Gatekeeper.
