What is Internet2?
a project
led by universities
to develop and deploy new Internet
applications and technologies
in order to meet the university
mission of research and education
History of Internet2
1986/7- 1995: NSFnet
1994/5: NSFnet privatized
1995/6: universities articulate requirements for next
generation networking
October 1996: Internet2 Project formed
October 1997: UCAID formed
April 1998: Abilene Project Announced
September 1998: Middleware Initiative Announced
January 1999: Abilene in Production
Internet2 Project Goals
Enable new generation of applications
Re-create leading edge R&E network
capability
Transfer capability to the global
production Internet

Internet2 Applications
Deliver qualitative and quantitative
improvements in the conduct of:
• Research
• Teaching
• Learning
Require advanced networking
Advanced Networking
Richer content through higher
bandwidth
• Video, audio
• Virtual reality
• Dynamic not static
More interactivity via minimal delay
Reliable delivery through quality of
service model

Middleware
Identify technologies that are
scalable and interoperable
• security
• collaborations services
 digital voice and video
• filters/agents for persistent online presence
• technologies for control of remote
instrumentation
• distributed file services
The Network
Services required in the network to
enable advanced applications:
• Establish quality of service (QoS)
• Support native multicast

Abilene Characteristics
2.4 Gbps (OC48) among gigaPoPs,
increasing to 9.6 Gbps (OC192)
Connections at 622 Mbps (OC12) or
155 Mbps (OC3)
IP over Sonet technology
Access PoPs very close to almost all
of the anticipated university
gigaPoPs
Abilene Schedule
Fall 1998: Demonstrated network at
member meeting, in pre-production
at several universities, connected to
Chicago switch for STAR TAP
Janurary 1999: Initial set of members
connected in production mode
By December 1999: around 65
institutions connected
Recap:
“It’s the applications, stupid!”
Bandwidth is important, but not
everything (think qos!)
Technology transfer is crucial:
universities (and everybody else)
need to buy this stuff in a
competitive commercial marketplace
