1. ASCR/ESnet Network Requirements an Internet2 Perspective 2009 ASCR/ESnet Network Requirements Workshop April 15/16, 2009 Richard Carlson -- Internet2

2. Basic Premise Large science projects have become, or are becoming, global collaborations Multiple investigators Multiple physical locations High-Performance infrastructure required to support scientific investigations and collaborations

3. Reframing the Science needs Question Conclusion based request I need 5 Gbps of bandwidth Science based request I need to move 2 TBytes in 1 hour I will move this amount of data once per day Users need ways to make effective complaints

4. Current Network Traffic Flows DoE-SC major funding source for U.S. scientific research DoE operates specialized instruments and facilities (labs) Majority of U.S. users located at Universities and other non-Lab sites

5. Current Network Architecture ESnet interconnects DoE Labs and peers with national and international partners Internet2 interconnect regional/state networks and peers with national and international partners Regional/State networks connect to University campus networks

6. Internet2 Background Member organization formed in 1996 30 Regional/State network connectors 211 Universities 11 Corporate partners 44 Affiliate members 60 International partners

7. Internet2 Management Member focused, Member led organization 18 member Board of Trustees 4 Advisory Councils Architecture & Operations Applications, Middleware, and Services Research External Relations All councils have CIO, Scientific Researcher, Regional Network, Industry, and Appointed representatives

8. Internet2 Strategic Planning Initiative 2008 – Community lead initiative to develop new strategic plan http://www.internet2.edu/strategicplanning/ 4 major goals, 8 strategic statements, 28 action items 2009 – Strategic implementation plans begin developed

11. Internet2 Collaboration Model Direct support to member institutions Indirect support for most funded member lead research projects Direct collaboration on specific funded research projects

12. End-to-End Performance Initiative perfSONAR International measurement infrastructure collaboration with ESnet, GEANT, and RNP Currently being developed and deployed Measurement tools OWAMP – One-Way Delay NDT – Advanced host/network diagnostics BWCTL – Advanced throughput measurement

13. Middleware and Security Shibboleth Multi-institution single sign-on (SSO) service Grouper Groups Management toolkit COmanage Identity-oriented requirements of common collaboration tools

14. Current Control Plane Developments Intra-domain Currently on the Ciena platform, to be deployed on the Infinera platform in the future Have an Installed working configuration on the Cienas Inter-domain Working with the DICE (Dante, Internet2, Canarie/LHC, ESnet) group Working on Topology, Path Computation and Scheduling, Signaling, and Lookup Services (think a circuit based DNS) Web service based communications Face-to-face meeting every three months and biweekly calls

16. Conclusions Internet2 is a “Member focused, Member led” organization Works closely with DOE, NSF and other Fed agencies to support community Strong collaborations with partners and peers Comprehensive set of services to support high-performance scientific collaborations

17. Supplemental Information

18. Using the Network Application’s performance should meet your expectations! 100 MB/s is reasonable 1000 MB/s is possible If they don’t you should complain! But you need to complain effectively if you want the problem fixed

19. Web Service based E-NNI Routing Topology Exchange Domain Abstraction Varying levels of dynamic information Resource Scheduling Multi-Domain path computation techniques Resource identification, reservation, confirmation Signaling path setup, service instantiation Host Lookup Service Uses DNS pointers

20. Dynamic Circuit Networks Web Service Control Plane Interfaces Web Services provides a mechanism to deal with heterogeneous control planes inspired by the standards bodies work on control plane protocols, but not just recreating that work at the web service level Ethernet/L2SC (Dataplane) SONET/TDM (Dataplane) Router(MPLS)/PSC (Dataplane) GMPLS (I-NNI) MPLS (I-NNI) Management System (I-NNI) Inter-Domain Controller (IDC) WS E-NNI WS UNI IDC WS I-NNI IF

22. Shared IP Network Juniper routers at 9 locations 10 Gbps links interconnect routers 20 Gbps on multiple links as required Router proxy allows access to current config’s and statistics Internet2 Observatory provides detailed utilization information

24. Network Research Example - Phoebus Phoebus - TCP data flows File transfers over long distance segments not requiring congestion control Lead by Martin Swaney at the University of Delaware

25. Nodes

26. Dynamic Circuit Network 21 Ciena Core Director multiplexor sites Dedicated circuits between 2 points site-to-site, cluster-to-cluster, or host-to- host One end-point may be non-Internet2 site Bandwidth steps from 51 Mbps to 10 Gbps Short duration (minutes to weeks) Long duration (weeks to years)

27. Nodes

28. Dynamic Circuit Network Similar to the IP network model, but using different protocols Connections are one armed Physical connection Control Plane Protocols Create Circuits in seconds for periods of hours to days Only through the Ciena equipment at the start, eventually evolving to the full platform
