1 Commodity and High-Speed Internet Access in American Research Universities Henning Schulzrinne Dept. of Computer Science, Columbia University Internet2 Fall Member Meeting Atlanta, Georgia November 1, 2000 With material borrowed from Internet2 and Abilene presentations

2 Overview Background on American university “hierarchy’’ Typical local network configuration Regional networks, GigaPOPs Internet2: vBNS, Abilene, … On-going efforts

3 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)

4 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

Carnegie Foundation ClassificationCarnegie 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)

8 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

9 University Network Typically, Mb/s switched in newer installations Possibly per-jack maintenance $ Student fees for computing

10 Example: Columbia University Network 1000Fx

11 University Network Connection Each university chooses independently (except for state systems) Regional network Internet2 Internet OC3-OC12nOC1-T3-OC3 e.g., NYSERnet e.g., Applied Theory Via GigaPOP

16 Internet2 “Internet2 is a consortium being led by over 180 universities working in partnership with 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.
