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
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
