  2. Internet2: an Overview Ana Preston Program Manager, International Relations Apreston@internet2.edu

  3. Outline • Background: why and who? • Focus areas and activities: what? • International partnerships: how? • Your questions……..

  4. Internet2 Mission and Goals • Develop and deploy advanced network applications and technologies, accelerating the creation of tomorrow’s Internet. • Enable new generation of applications • Create leading edge R&E network capability • Transfer technology and experience to the global production Internet

  5. Internet2 Members +200 universities (yellow dots)

  6. Additional Membership • Over 70 Internet2 Corporate Members • Over 40 Affiliate Members • Government Research Agencies • Internet2/U.S. Government: • separate but interdependent • Internet2 is led by higher education • Focused on research and education needs

  7. Why University Leadership? • The Internet came from the academic community • Stanford -- the Internet protocols • NSFNet -- the scaled-up Internet • CERN -- the WWW protocols • University of Illinois -- the Web browser • Universities’ research and education mission require an advanced Internet and have demonstrated they can develop it

  8. Internet2 Partnerships • Internet2 universities are recreating the partnerships that fostered the Internet in its infancy • Industry • Government • International

  9. Internet2 Goals • Enable new generation of applications • Re-create leading edge R&E network capability • Transfer technology and experience to the global production Internet

  10. How Internet2 works • Universities commit: • Engineering lead: connect university to rest of Internet2 community, deploy new technologies • Applications lead: support apps development on campus • Working groups: • Of expert/interested individuals within community • Chaired by volunteer (sometimes by staff) • Staff support • Projects: Abilene • Internet2 Staff • Focus Areas

  11. Internet2 Focus Areas • Advanced Applications • Middleware • Engineering • Advanced Network Infrastructure • Partnerships

  12. Success of the Internet Millions of People Source:Nua Internet Surveys

  13. History • ARPAnet origins • 1987 -- NSFnet • Privatization in 1995 • 1996 • Telecomm Act • The WWW explodes • Federal Next Generation Internet Initiative • NSF provides grant funding to universities for network infrastructure • Internet2 founded • 1999 • Abilene in production

  14. Today’s Internet Doesn’t • Provide reliable end-to-end performance • Encourage cooperation on new capabilities • Allow testing of new technologies • Support development of revolutionary applications

  15. Internet2 Applications • What are “Internet2 applications”? • They deliver qualitative and quantitative improvements in how we conduct research and engage in teaching and learning • They require advanced networks to work

  16. Sciences Arts Humanities Health care Business/Law Administration … Library Classroom Clinic Office Laboratory Dorm room … Different Disciplines/Contexts

  17. Advanced Application Attributes • Interactive collaboration & instruction • Real-time access to remote resources • Large-scale, multi-site computation • Distributed data storage and data mining • Shared virtual reality • Dynamic data visualization • Any combination of the above

  18. Digital Video Applications • Up to broadcast quality videoconferencing • Both live distribution and on-demand access to a variety of content • HDTV-based digital cinema, network-based studio production, …

  19. Teaching Music with Advanced Network Videoconferencing • Real-time interaction with the world’s foremost master teachers of music • Accurate representation of sound • Supplement to traditional music teaching University of Oklahoma http://music.ou.edu/internet2/

  20. Video Futures • Tele-immersive “Office of the Future” Source: University of North Carolina

  21. Telepresence environment • Real-time interactions with very high quality audio and MPEG-2 video • as needed “meetings” connecting faculty and staff across the ocean • via DFN  GEANT (2 2.5 Gigabit per second to Abilene)

  22. Access Grid www.accessgrid.org Source: Argonne National Laboratory

  23. Remote Scanning Electron Microscope The University of Michigan

  24. Philips XL30

  25. The Grid Instruments Libraries Workstations People Data sets

  26. What is the Grid? • Global resources available to communities of researchers • The protocols, services, and applications that enable new forms of collaboration

  27. Petabyte scale environment for data-intensive applications (Large Hadron Collider, Sloan Digital Sky Survey, Laser Interferometer Gravitational Wave Observatory) www.griphyn.org Example: Grid Physics Network - GryPhyN

  28. Internet2 Discipline & Community Activities

  29. Approach Broad Outreach Internet2 Days, web site, application flyers Health Sciences Arts & Humanities NEES, Physics, Astronomy Applications Community Applications Community Applications Community Applications Community Applications Community Applications Community Applications Community Applications Community

  30. Health Sciences Veterinary Medicine Arts & Humanities Non-traditional Theses Arts Performance High Energy and Nuclear Physics Geospatial Information Systems … Voice over IP Digital Video Videoconferencing ResearchChannel Network Storage … Applications Working Groups

  31. Support of Community through Knowledge Sharing • Internet2 acts as a clearinghouse to help distribute information • Technical meetings • Virtual presentations • Development of demonstrations and tools • Cooperate on standards to maintain global interoperability • Technical Support • Software tools (monitoring, diagnostic) • Loaner hardware (Vbrick, Cakebox, Access Grid) • Access to expertise (working groups)

  32. Other Resources • Distributed Applications Support Team • dast.nlanr.net • Internet2 End-to-End Performance Initiative

  33. End-to-End Performance Initiative • To enable the researchers, faculty, students and staff who use high performance networks to obtain optimal performance from the current infrastructure on a consistent basis. Raw Connectivity Applications Performance

  34. True End-to-End Performance requires a system approach • User perception • Application • Operating system • Host IP stack • Host network card • Local Area Network • Campus backbone network • Campus link to regional network/GigaPoP • GigaPoP link to Internet2 national backbones • Internationalconnections EYEBALL APPLICATION STACK JACK NETWORK . . . . . . . . . . . .

  35. Internet2 Focus Areas • Advanced Applications • Middleware • Engineering • Advanced Network Infrastructure • Partnerships

  36. Middleware } Applications • Authentication, Identification, Authorization, Directories, Security Advanced Network Services (Distributed Network Middleware) Advanced Physical Network Infrastructure

  37. Internet2 Middleware Initiative • Focus on core middleware as infrastructure • Interoperability • 190 universities will never buy the same software • Getting stuff implemented • Best practices • Integrate across applications • Discourage ‘islands’ of middleware infrastructure • E.g. core middleware just for this particular grid project • Enable community to share resources • Grid, remote instruments, shared classes

  38. I2MI core middleware activities • Identifiers • Early Adopters - survey/docs about how campuses are assigning and relating identifiers • Authentication • WebISO (Web Initial Sign-on): share expertise, code • Directories • DoDHE: Dir. of Directories for HE: inter-institutional directory searching, using eduPerson and LDAP Recipe • eduPerson: an LDAP object class that includes widely-used person attributes in higher education • LDAP Recipe: promote common design • Authorization • Certificates and PKI • Internet2 PKI Labs
