Outline
• Internet2 Background• Internet2 New Technology Development and Deployment Experiences
• Beyond the Network• Internet2 and Malaysia
![Page 3: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/3.jpg)
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
![Page 4: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/4.jpg)
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
![Page 5: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/5.jpg)
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

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

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

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
![Page 10: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/10.jpg)
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

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

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

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
![Page 18: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/18.jpg)
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
![Page 19: The Research and Education Network: Platform for Innovation Heather Boyles, heather@internet2.edu Next Generation Network Symposium Malaysia 2007-March-15](https://reader035.vdocuments.site/reader035/viewer/2022070409/56649ea05503460f94ba29fd/html5/thumbnails/19.jpg)
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

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

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
