Commodity and High-Speed Internet Access in American Research Universities Henning Schulzrinne hgs@cs.columbia.edu Dept. of Computer Science, Columbia University Internet2 Fall Member Meeting Atlanta, Georgia November 1, 2000 With material borrowed from Internet2 and Abilene presentations
Overview • Background on American university “hierarchy’’ • Typical local network configuration • Regional networks, GigaPOPs • Internet2: vBNS, Abilene, … • On-going efforts
American Education Hierarchy • Research I institutions: • PhD-granting • Large (gov’t funded) research programs • Private (Columbia, Harvard, Yale, NYU) or public (UMass, UC) • Four-year institutions – generally, do not grant PhDs (but BS, BA)
American Education Hierarchy • Two-year (“community”) colleges -> butte.cc.ca.us • K-12: kindergarten through high-school (“secondary education”) • Special category: HBCU = historically black colleges and universities – special programs for research and connectivity
2000 Carnegie Foundation Classification • Doctoral/Research Extensive (> 50 Dr./year) • Doctoral/Research Intensive (>10 Dr./year) • Master’s Colleges & Universities I, II • Baccalaureate Colleges (Liberal Arts, General) • Associate’s Colleges • Specialized (Theological, medical, E&T, business, art/music/design, law, teachers)
Research I Networking • Originally, all connected to ARPAnet and NSFnet • Still partially subsidized by NSF, but for high-speed connectivity only • Commodity Internet paid for by normal operational funding
University Network • Typically, 10-100 Mb/s switched in newer installations • Possibly per-jack maintenance $ • Student fees for computing
University Network Connection • Each university chooses independently (except for state systems) Internet e.g., NYSERnet Regional network Internet2 e.g., Applied Theory Via GigaPOP nOC1-T3-OC3 OC3-OC12
University Network Connectivity • Policies differ • Automatic routing via commodity or Internet2 • Some, only selected labs or hosts 1 brooklyn (128.59.16.64) 1 ms 1 ms 1 ms 2 mudd-edge-1.net.columbia.edu (128.59.16.1) 2 ms nyser-gw.net.columbia.edu (128.59.1.4) 1 ms 1 ms 3 nn2k-gw.net.columbia.edu (128.59.1.6) 1 ms 1 ms 1 ms 4 199.109.5.6 (199.109.5.6) 2 ms 2 ms 1 ms 5 199.109.5.2 (199.109.5.2) 2 ms 2 ms 2 ms 6 wash-nycm.abilene.ucaid.edu (198.32.8.45) 7 ms 7 ms 6 ms 7 vbns-abilene.abilene.ucaid.edu (198.32.11.10) 9 ms 9 ms 9 ms 8 jn1-so7-0-0-1.wor.vbns.net (204.147.136.137) 9 ms 10 ms 9 ms 9 jn1-at1-0-0-17.cht.vbns.net (204.147.132.130) 14 ms 13 ms 13 ms 10 border1-rt-at6-0-0.gw.umass.edu (128.119.3.129) 28 ms 21 ms 22 ms 11 cs-gw-ext-i2.cs.umass.edu (128.119.3.146) 24 ms 22 ms 23 ms 12 kernighan.cs.umass.edu (128.119.240.46) 25 ms 28 ms 24 ms
University Challenges • Universal connectivity: Ethernet in every dorm room and lecture hall • Wireless networks (802.11b) • VoIP • Multimedia conferencing • Napster
Internet2 “Internet2 is a consortium being led by over 180 universitiesworking in partnershipwith industry and government to develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow's Internet. Internet2 is recreating the partnership among academia, industry and government that fostered today´s Internet in its infancy. The primary goals of Internet2 are to: • Create a leading edge network capability for the national research community • Enable revolutionary Internet applications • Ensure the rapid transfer of new network services and applications to the broader Internet community.
Internet2 Partnerships • Internet2 universities are recreating the partnerships that fostered the Internet in its infancy • Industry • Government • International • Participation fee $20,000 per annum
3Com Advanced Network & Services Alcatel Ameritech AT&T Cisco Systems IBM ITC^Deltacom Lucent Technologies Marconi WorldCom Microsoft Newbridge Networks Netcom Systems Nortel Networks Qwest Communications SBC Communications WCI Cable Internet2 Corporate Partners
Additional Participation • Over 70 Internet2 Corporate Members • Over 30 Affiliate Members • Over 30 International Partners
Internet2 Goals • Enable new generation of applications • Re-create leading edge R&E network capability • Transfer technology and experience to the global production Internet
Why Internet2? • The Internet was not designed for: • Millions of users • Congestion • Multimedia • Real time interaction • But, only the Internet can: • Accommodate explosive growth • Enable convergence of information work, mass media, and human collaboration
Internet2 Focus Areas • Advanced Network Infrastructure • Middleware • Engineering • Advanced Applications • Partnerships

National Networks • Internet2 Backbone Networks • vBNS • Abilene • Federal Backbone Networks • DREN • ESnet • NREN • SuperNet • …
Abilene – October, 2000 • Inflection point in network development • OC-48c (2.5 Gb/s) IP-over-SONET backbone • 53 current and pending connections in 32 states • Second OC-48c connection: SoX • 175 participants in 47 states and D.C. • Ongoing strong partnership • Cisco, Nortel, Qwest, Indiana Univ., ITECs (NC and OH) • Increasing backbone utilization • Characteristic exponential growth • O(OC-12c) peak utilization on some links • Traffic doubling time: 7 months
Abilene Core – autumn 2000 Seattle New York Cleveland Indianapolis Sacramento Washington Denver Denver Kansas City Los Angeles Atlanta Houston
Summary • Universities and state university systems are largely independent • But mostly cluster into regional networks (from NSFnet days) and Internet2 • vBNS (1995-2000) -> Abilene, …
