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

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 Slide 2

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. Slide 3

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 Slide 4

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 Slide 5

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, nearzero 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. Slide 6

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

8 ORGANIZATION Internal Organization Advanced Network Infrastructure Applications Engineering Middleware Partnerships Internet2 is primarily an organization driven by our membership Slide 8

9 ORGANIZATION: Membership Internet2 Members 189 universities (yellow dots) 70 corporations 40 non-profits and gov t labs Slide 9

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 Slide 10

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

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 LOSA UNINET OC 12 NYCM BELNET, CA*net3, GEANT 1, HEANET, JANET, NORDUnet SAN DIEGO (CALREN2) CUDI EL PASO (UACJ-UT EL PASO) CUDI OC 3-12 AMPATH ANSP, REUNA, RNP2 RETINA 1 ARNES, CARNET, CESnet, DFN, GRNET, RESTENA, SWITCH, HUNGARNET, GARR-B, POL-34, RCCN, RedIRIS Slide 13

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 Slide 14

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) Slide 15

16 ABILENE Next Generation Abilene 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 λ 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 Slide 16

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) Slide 17
