Presentation Transcript

  1. The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15

  2. Outline • Internet2 Background • Internet2 New Technology Development and Deployment Experiences • Beyond the Network • Internet2 and Malaysia

  3. Internet2 • Supports high-performance networking for U.S. research, universities • Develops and deploys next-generation network technology • Enables collaborations among the community that advance networking applications and protocols

  4. Brief Background • US National Science Foundation NSFnet • First ‘Internet’ connectivity for many US universities • Decommissioned 1994/5 • Universities to use commercial Internet connections • NSF funds vBNS to interconnect supercomputer centers – 1995 • Outsourced to MCI • In parallel, meetings through 1995-6 resulting in Internet2

  5. Why? • Commercial Internet ‘working’ but not meeting specific needs of research, teaching, learning • Focused on buildout to residences, businesses • Little control of service quality to support especially high-end needs of universities • Recognition that vBNS needed to be expanded, but community had limited control • Recreate innovation of NSFnet period

  6. Internet2 - today • US-based membership organization • 207 US University members • 66 Corporate members • 47 Affiliate members • Including several US government research labs • 2 Association members • 46 International partnerships • Budget more than $25 million per year

  7. Internet2 Network • Hybrid optical and IP network • Dynamic and static wavelength services • Fiber, equipment dedicated to Internet2; Level 3 maintains network and service level • Platform supports production services and experimental projects

  8. Internet2 Network - Layer 1 Internet2 Network Optical Switching Node Level3 Regen Site Internet2 Redundant Drop/Add Site ESnet Drop/Add Site

  9. Capabilities • Capacity and reliability to serve large scale projects – eVLBI, LHC, NEON, TeraGrid • Flexibility to support smaller projects at lower bandwidths, for variable durations • Lightpath provisioning to the campus • Ideal platform for network research

  10. Control • Over years, level of control has evolved • Down the network layers • Now: control dedicated fiber pair, optical equipment • Control of services provided • IPv6, multicast • Now: new hybrid circuit + packet services • Ability to meet both goals • Meet day to day (“production”) needs of members • Provide platform for development of new services, uses, applications

  11. History of IPv6 in Internet2 • Tunnel network deployed 2001 • First IPv6 tutorial at Lincoln joint-techs meeting • Migration to native, dual stack implementation at end of 2001 • Before upgrade began • Using Cisco GSR routers • Began migration of connectors • Native dual stack was default for the upgrade to Juniper T640 routers • Early testing • 8 gig tests from Sunnyvale to Washington DC • IPv4, IPv6, and mixed IPv4/IPv6 • No distinguishable difference in performance

  12. Still Working Well • Our dual-stack IPv6 network continues to perform well • Active testing shows no difference between IPv4 and IPv6 performance • Changes: improving connectivity to others

  13. IPv4/IPv6 Comparative Performance Graphics

  14. Abilene IPv6 Growth

  15. Policy: Interconnection with other networks • Peering with commercial v6 networks in order to encourage adoption, deployment • With new Internet2 network, will also now peer with IPv4 commercial networks

  16. IPv6 Activities • Internet2 IPv6 Working Group • Refocusing from campus deployment effort to….. • Working with middleware and applications working groups as resource • Internet2 IPv6 Hands-on Workshops • Lesser in frequency, but still being held by request • Next one in April: Merit (Michigan state network) hosting: IPv6 Multicast Hands-on Workshop

  17. Technology Development and Deployment Experience • Internet2 has provided platform for deploying native IPv6 • On large scale • In production environment • Other technologies • IP layer QoS (DiffServ) • Multicast • Dynamic circuit services

  18. Applications End-to-end Performance Security Motivate Enable Middleware Services Networks Beyond the Network Infrastructure

  19. Beyond the network • Common infrastructure needs above network layer to support members’ needs/use of network • Performance: measurement and monitoring infrastructure from end to end • perfSONAR infrastructure • Cross-community collaboration needs inter-institutional authentication, authorization infrastructure • InCommon federation

  20. Fine Arts Rehearsal and Performance

  21. Health Science Research and Instruction

  23. Collaboration and Communication

  24. MYREN and Internet2 • Memorandum of Understanding since July 2006 • Connectivity via MYREN connection to TEIN2 and onto US via NSF-funded TransPAC2 project • Platform upon which build collaborations
