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
