October 1997
8 months ago:
Abilene Launched
April 1998
Today
135 universities
44 corporations
7 gigaPoPs connected to vBNS
Abilene demonstrated/nearing
production
Abilene peering with vBNS,
CANARIE
QoS -- QBone initiative launched
Middleware initiative launched
Challenges
Maintain focus on advanced Internet
• Production Internet rapidly gaining strength
through incremental improvements
• Intranets and extranets growing
Higher education needs a production
Internet capable of serving missioncritical applications
• and so does the rest of the world!
Internet2 implements advanced
capabilities
Next Steps
Continue to interconnect member
desktops and servers at high speed
Continue to support advanced
applications development
• focus on multi-campus implementations
Adopt, develop and implement
• QoS end-to-end
• middleware end-to-end
• new business models
Abilene
Objectives for the Abilene
Network
High availability backbone network
for advanced research applications
Separate network to test advanced
network capabilities
Quality of Service standards to
guarantee types of availability
Multicasting and advanced security
“Separate network” to do
network research
Progress
Demonstrated September 1998
In production January 1999

The QBone Initiative
What is “the QBone”
Vision
• Significant subset of the Internet implements welldefined notions of QoS and is regarded by users
as infrastructure
Testbed
• Interdomain DiffServ testbed being built by R&E
networks
• Infrastructure only a graduate student could love
Initiative
• Internet2 initiative that includes
 QBone testbed (QIG)
 Intradomain solutions group (QSG)
QBone Call for Participation
CFP issued September 25th, 1998
Proposals due October 16th
Review complete October 30th

Middleware
Middleware Challenges
Identify technologies that are
scalable and interoperable
Increase deployment of middleware
technologies as part of a precommercial production environment
Examples:
• Distributed storage - I2-DSI initiative
