  1. http://apps.internet2.edu/talks/ Internet2 Status and Plans SC99 -- 17 November 1999

  2. Agenda • Introduction: Doug Van Houweling • Applications: Ted Hanss • Distributed Storage: Micah Beck, UT-Knoxville • Network Engineer: Guy Almes • Measurement: Matt Zekauskas • QoS: Ben Teitelbaum

  3. Internet2 • Not for profit consortium of universities, corporations, and laboratories to advance Internet technology & applications • Funded through member dues, grants and fees for network service • Works by focusing, coordinating and aggregating support for member activities

  4. ITC^Deltacom Lucent Technologies MCI Worldcom Microsoft Newbridge Networks Nortel Networks Qwest Communications StarBurst WCI Cable 3Com Advanced Network & Services Alcatel Ameritech AT&T Cabletron Systems Cisco Systems FORE Systems IBM Internet2 Corporate Partners

  5. Internet2 Corporate Sponsors • Bell South • Compaq • Ericsson (formerly Torrent Networking Technologies) • Litton Network Access Systems • Novell • SBC Technology Resources • StorageTek

  8. Internet2 & the SC Community • Internet2 believes the work of your community is one of the primary applications drivers for our work • We welcome the challenge of supporting the needs of your advanced applications • We want to make your capabilities available to scholars here and elsewhere across the world

  9. The Internet2 Foci • Advanced Applications Development • Ted Hanss • Advanced Network Infrastructure • Guy Almes & Matt Zekauskas • Middleware Infrastructure for Higher Education and Research • Ted Hanss & Micah Beck • New Networking Capabilities • Guy Almes & Ben Teitelbaum • Technology Transfer • Partnership and Awareness

  10. Applications

  11. Sciences Arts Humanities Health care Business/Law Administration … Instruction Collaboration Streaming video Distributed computation Data mining Virtual reality Digital libraries … Different Disciplines/Contexts

  12. Interactive research, collaboration, and instruction Real-time access to remote resources Application Attributes

  13. Large-scale, multi-site computation and database processing Shared virtual reality Any combination of the above Attributes, cont.

  14. Campus & Discipline Outreach • Internet2 Days • Talks and demos at discipline conferences • Working jointly with NLANR • dast.nlanr.net

  15. I2 Middleware Initiative:The “Services Rich” Network Environment

  16. Or“From Circuits to Services”

  17. What’s an Ideal “Internet2” • Functional services available to users and developers • Enabling new collaborations and applications • Supported as production quality • An integrated framework • Scaled to the size of the research and education community

  18. Identifiers for people, objects, groups Authentication for people, objects and groups Directories to store common information Applications that use all of the above The Core

  19. I2 Middleware Activities • Early Harvest “Techshop” • Early Adopters

  20. Measurements in Internet2 Matt Zekauskas <matt@internet2.edu> SC99 Portland, OR November, 1999

  21. ‘My application has a problem’ • Where is it?Network? Host (stack,config)? Application? • Local passive measurements can help localize the problem • Consistent measurement throughout Internet2 infrastructure can help diagnose network problems (and also help localize the problem)

  22. Other Measurement Goals • Network engineering • Network research • Feedback to applications • Operational data • performance, flows, anomalies • Network characterization • how used? load response? SLS?

  23. Today • All: at least SNMP statistics • Backbones: (vBNS, Abilene) publishing • http://www.vbns.net/ • http://www.abilene.iu.edu/ • Various uncoordinated activity

  24. Today • Active measurement efforts: AMP (NLANR/MOAT), Surveyor (Advanced), {PingER} • http://moat.nlanr.net/AMP/ • http://www.advanced.org/surveyor/ • Passive measurement effort: NAI (OCXmon) (NLANR/MOAT) • http://moat.nlanr.net/

  25. Delay Between Two East-Coast Tele-Immersion Sites

  26. Working Group Activities • Measurement architecture • Encourage common • Measurements, tools • Parameters • Reporting • Work with (at least) network management, QoS, multicastworking groups

  27. Ideal • Consistent measurement of • Utilization • Performance • Traffic Characterization • With generally available results • Combined with “well known” measurement targets/observatories for on-demand tests

  28. Also • Want some way to know where loss occurs when it happens (or delay) • Advanced service debugging • Multicast • QoS (QBone designing measurement in), additional E-E service verification?

  29. Reporting • All measurements available via Web • Site/Router-relative URLs • allows computed URL • I2-Wide measurements page to allow for browsing • Need to be cognizant of security & privacy issues • mainly passive measurements

  30. On the Horizon: TAAD • Traffic Analysis and Auto Diagnosis • Developed by Matt Mathis and Kathy Benninger at NLANR ES • Works on data collected by OCXmon (passive) • Automatically diagnose specific types of TCP/IP performance problems • Network limited flows • Mis-tuned application or TCP stack • When complete, available at: http://www.ncne.nlanr.net/TCP

  31. Summary • Consistent measurement of • Utilization • Performance • Traffic Characterization • That are made generally available • Plus targets/observatories • In support of applications and the networks themselves • http://www.internet2.edu/measurement
