  1. Internet2:Presentation to Astronomy Community at Haystack T. Charles Yun April 2002

  2. INTRODUCTION & OVERVIEW Presentation Outline • Applications 5 min • Examples of current projects • About Internet2 5 min • Organization, Membership • Internet2 & Abilene 10 min • Backbone, Characteristics, Connections • Q and A 5 min total time ~25 min Internet 2 Applications Update

  3. INTRODUCTION & OVERVIEW Astronomy & Internet2 • What does Internet2 have to offer for the astronomy community? • Access to advanced, high-performance network • Find parallels with work being done by other communities • Connections to researchers & peers around the world (BOF/Working Group) • Loaner hardware, expert advice, etc. Internet 2 Applications Update

  4. APPLICATIONS Attributes of Advanced Apps • Provide qualitative and quantitative improvements in how we conduct research and engage in teaching and learning • Common attributes: • Remote instrumentation and interactive collaboration • Distributed data storage and data mining • Large-scale, multi-site computation • Real-time access to remote resources • Dynamic data visualization • Shared virtual reality Internet 2 Applications Update

  5. APPLICATIONS: HDTV Raw HDTV Stream • Packetized raw HDTV (1.5 Gbps) • SC2001 public demo • DARPA PIs Meeting: SEA->DC area 1/6/02 • Application level measurement • 3 billion packets transmitted • 0 packets lost, 15 resequencing episodes • e2e network performance • Loss: <8x10 -10 (90% confidence level) • Reordering: 5x10 –9 • Transcontinental 1-Gbps TCP (std 1.5 kB MTU) requires loss at the level of 3x10 –8 or lower Internet 2 Applications Update

  6. APPLICATIONS: GRIDs HENP and NEESgrid • High Energy and Nuclear Physics • Transferring petabytes of data a year, gigabytes per second per experiment • Cascading data storage model, near-zero packet loss per data stream, distributed database for end-user data manipulation • VRVS collaboration system supports multiple video formats and technologies • Network for Earthquake Engineering Simulation • Running hybrid experiments synchronizing physical and computational experiments • Synchronizing large volumes of data of different types: sensor, video, etc. Internet 2 Applications Update

  7. Commercialization Privatization Today’s Internet Internet2 Research and Development Partnerships ORGANIZATION Internet2 Mission • Develop and deploy advanced network applications and technologies for research and higher education, accelerating the creation of tomorrow’s internet. • Supporting advanced service efforts such as: • Multicast • IPv6 • QoS • Measurement • Security Internet 2 Applications Update

  8. ORGANIZATION Internal Organization • Advanced Network Infrastructure • Applications • Engineering • Middleware • Partnerships • Internet2 is primarily an organization driven by our membership Internet 2 Applications Update

  9. ORGANIZATION: Membership Internet2 Members 189 universities (yellow dots) 70 corporations 40 non-profits and gov’t labs Internet 2 Applications Update

  10. ABILENE Internet2 Network Backbone • Abilene • The name of Internet2’s network infrastructure • Apr 1998: Project announced at White House • Jan 1999: Production status for network • 12 GigaPOPs around the conuntry • NOC located at Indiana University Internet 2 Applications Update

  11. Seattle Cleveland Chicago New York Sacramento Indianapolis Washington, DC Sunnyvale Denver Kansas City Los Angeles Los Angeles Atlanta OC 48 OC 12 Houston ABILENE Backbone Capacity Partners: Qwest, Cisco, Nortel, Indiana University Today: OC48 Packet over Sonet, multicast, IPv4 & IPv6, QOS (DiffServ) Internet 2 Applications Update

  12. Internet 2 Applications Update

  13. ABILENE International Transit Network PACIFIC WAVE AARNET, APAN/TransPAC, CA*net3, TANET2 STAR TAP/STAR LIGHT APAN/TransPAC, Ca*net3, CERN, CERnet, FASTnet, GEMnet, IUCC, KOREN/KREONET2, NORDUnet, RNP2, SURFnet, SingAREN, TAnet2 SNVA GEMNET, SINET, SingAREN, WIDE OC 12 NYCM BELNET, CA*net3, GEANT1, HEANET, JANET, NORDUnet LOSA UNINET SAN DIEGO (CALREN2) CUDI EL PASO (UACJ-UT EL PASO) CUDI AMPATH ANSP, REUNA, RNP2 RETINA OC 3-12 1ARNES, CARNET, CESnet, DFN, GRNET, RESTENA, SWITCH, HUNGARNET, GARR-B, POL-34, RCCN, RedIRIS Internet 2 Applications Update

  14. ABILENE Networking Activity • Internet2 networking is a fundamentally hierarchical and collaborative activity • International networking • Ad hoc -> Global Terabit Research Network (GTRN) • National backbones • Regional networks • GigaPoPs • Campus networks • Much activity now at the metropolitan and regional scales Internet 2 Applications Update

  15. ABILENE Future of Abilene • Qwest has extended commitment for another 5 years – to October 2006 • Upgrade of Abilene backbone to optical transport capability • 4 times increase in core bandwidth, to 10 gigabits/second (OC 192) • New wavelength capabilities (MWDM) Internet 2 Applications Update

  16. Native IPv6 Motivations Resolving IPv4 address exhaustion issues International collaboration Run natively - concurrent with IPv4 Replicate multicast deployment strategy Close collaboration with Internet2 IPv6 Working Group on regional and campus v6 rollout Network resiliency Increasing use of videoconferencing & VoIP impose tighter restoration requirements (<100 ms) Abilene ’s will not be protected like SONET Addition of new measurement capabilities Active & passive probing Surveyor, Abilene “Observatories,” Performance beacons Latency & jitter, loss, TCP throughput ABILENE Next Generation Abilene Internet 2 Applications Update

  17. CONCLUSION Where to go from here… • Working Group or BOF meeting • Identify tasks, activities and goals pertinent to the community • Select an already established meeting at which to hold a BOF meeting • Determine individuals who are willing to lead a working group • Identify a schedule against which activities can be measure (don’t let the inertia stop) Internet 2 Applications Update
