What is R&E Networking?
• Internet for the Research and Education Community.– Research Universities– Colleges and Teaching Universities– Schools– Some commercial research labs (e.g. Microsoft
Research).
• Often referred to as Internet2.

What is Internet2?
• National Backbone Network– also National Lambda Rail (NLR)
• Advanced Networking in General– Peachnet (Georgia State-wide R&E network)– Southern Crossroads (SOX) Gigapop and Regional
Optical Network.• Umbrella organization for applications
communities– e.g. Philadelphia Orchestra

What R&E Networking isn’t.
• Not commercial, unless it is.– e.g. ticket sales.
• Not myspace/facebook, but sometimes.– SOX Peers with Google.
• Not to be confused with Web 2.0

Peachnet
• Peachnet passes within 5 miles of 35 school district offices.
• SOX connects most of the R&E institutes in the South East to National and International destinations.

SEGP
• Sponsored Education Group Participant.• SOX sponsors Peachnet.• Any K-12 District connecting to Peachnet will
get connectivity to Internet2/NLR via SOX.• Improve performance, enabling access to rich
content.

Why not Internet1 (1/2)?
• EdTechNext mentions slow and unreliable connections, pop-up adds etc.
• 10 years ago, R&E community faced similar challenges.– lack of capacity, routing, etc led to formation of
Internet2 organization, Abilene and regional gigapops.
• R&E Networking launched research into new era.

Why not Internet1 (2/2)?
• R&E is not competing with ISPs.– K-12 doesn’t “compete” with Universities– Large corporations build their own networks.
• We need AT&T, Level3, Qwest, AGL etc– Fiber providers
• But we want– Separate Layer 3 service with high capacity
connections and direct routing between sites.

Capacity.
• Congestion causes packet loss and delay.• Interactive applications are harder to use.• Even non-interactive applications are slow.• Bandwidth is required but not sufficient– Also latency, jitter, routing.

What Else Is It Good For?
• The applications mentioned on the MUSE site (http://k20.internet2.edu):– videoconferencing (D2D)– teleimmersion/telepresence (Gray’s Reef)– remote control of scientific instrumentation (ORNL)– Sensors, simulations, haptics

Beyond the Bandwidth Barrier
• Additional capacity is just the first step.• What becomes possible if there was almost
unlimited bandwidth?• R&E networking enables advanced
applications for new learning experiences.• Also see http://ceap.wcu.edu/houghton/i2

Next Steps
• Equipment and Professional Development– To make optimal use of R&E networking, you
need to have the classroom-side equipment and professional development for teachers who need to know how to use it to further learning.

Summary - What is R&E Networking?
• A network, advanced networking, and the applications it enables.
• Fourth Leg (for added stability)– Enthusiastic participants
• Key component of 21st Century learning.• Potential.
