Internet2: nuevas aplicaciones gracias a la banda ancha Heather Boyles INTERNET’99 4 de febrero Madrid 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 UCAID Member Universities 141 Members as of January 1999 University of Puerto Rico not shown Internet2 Corporate Partners 3Com Lucent Technologies Advanced Network MCI Worldcom & Services, Inc.

Technology transfer is crucial: universities (and everybody else) need to buy this stuff in a competitive commercial marketplace More Information Me: • [email protected] Internet2 • www.internet2.edu Abilene • www.internet2.edu/abilene UCAID • www.ucaid.edu
