What should we talk about?
Here are questions I hope to answer:•What is Internet2 all about?
•How is it different from “Internet1”?
•What is Abilene and why should I care?
•Why is Middleware like underwear?
•Does E+2+E+P = ☺?
•What are the benefit to MTSU?
Questions & comments are welcome!
What is Internet2 all about?
Our Mission & GoalTo develop and deploy advanced network applications and technologies for research and higher education, accelerating the creation of tomorrow’s Internet.
What do we do?We support deployment of required advanced application services:
IPv6QoSMeasurementSecurityMulticast
How are we organized?•Board of Directors – University presidents/chancellors are the voting representatives•Advisory councils with Board seats
Applications Strategy Network Planning/Policy Network Research Liaison Industry Liaison Council
How does the necessary work get done?
The “Work” is assigned to internal Groups which work with (and for!) our members
•Applications
•Engineering
•Middleware
•Network Infrastructure
•Partnerships
Where are the Members?202 universities66 corporations40 non-profits & gov’t labs

Internet2 LSN
What about the Federal Gov’t?
Separate but Interdependent
How is it different from “Internet1”?
It’s more than email & eBay!
It’s all about Advanced Applications!1. They deliver qualitative and quantitative improvements in
how we conduct research and engage in teaching and learning.
2. They require advanced networks to work.
Common attributes of such applications:• 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
Where would you need or find such Applications?
Different disciplines•Sciences•Arts•Humanities•Health care•Business/Law•Administration•…
Different places•Library•Classroom•Clinic•Office•Laboratory•Dorm room•…
For example … Science & Engineering
High Energy and Nuclear Physics (HENP)
Generating multi-petabyte datasets, gigabytes per second per experiment, requires a cascading data storage model, near-zero packet loss per data stream, and a distributed database for end-user data manipulation.
Each experiment requires input from hundreds of researchers around the world.
Network for Earthquake Engineering Simulation (NEESGrid)
Running hybrid experiments, synchronizing physical and computational experiments.
Synchronizing large volumes of data of different types: sensor, video, etc.
For example … Health Sciences
3D Brain Map•Visualization of data: real-time MRI, previously stored data, etc.
•Computational information transferred to supercomputers and used to understand brain functions in real time
•Very large multi-dimensional, multi-modal, time-varying data sets
Biomedical Informatics Research Network (BIRN)
•Extremely large data sets and repositories•Dynamically generate 3D visualizations from medical records
•Generating 36 Gbytes/day, so new models for search, retrieval, and analysis will be necessary
For example … Arts & Humanities
University of Oklahoma Master Classes (Brian Shepard)
•High fidelity video and audio via MPEG2•Optimized latency, audio/video synchronization
•Connecting Oklahoma with the New World Symphony in Miami, Florida
Dancing Beyond Boundaries:Distance Collaborative Dance
Performance at SC2001•Hybrid performance combining local and remote performances between Florida, Minnesota, Denver, and Brazil
•Synchronizing choreography across the continent
For example … Remote Collaboration
Virtual Room Videoconferencing System (VRVS) & the
Access GridSupport multipoint video-conferencing, where distributed reflectors spread computationally expensive responsibility
For example … Remote Control
Space Physics and Aeronomy Research Collaboratory
SPARCUniversity of Michigan
Reduced problems related to:
•Travel (both location & cost)
•Time, space, and temperature
•Limited faculty/student access
For example … can extend to K12
Oklahoma – music instruction to K12
VRVS – language class exchange (English/Spanish)
Physics/Science community – “Cootie” on www.beowulf.org
H.323 sharing AP classes among K12 schools in the same county
What is “Abilene” and why should I care?
Because you need a really Big Network for Advanced
Applications!
Abilene … a really BIG NETWORK
We needed one, so we “built” one … with a lot of help!•vBNS – uncertain future, uncertain funding•April 1998: Project announced at White House•Jan 1999: Production status for network
Partners: Qwest, Cisco, Nortel, Juniper, Indiana University
… it’s not free … but it’s cheap!•“on-ramps” are available from 12 GigaPops
Abilene backbone covers the Country
Here’s who is using Abilene
Can I rely on Abilene?
It’s going to be around for a while!• Original agreement with Qwest was amended on 1 October 2001
• Extension of Qwest’s original commitment for another 5 years, to October 2006
It’s “growing up” and will continue to support Advanced Applications• Upgrade of Abilene backbone to optical transport capability
• 4 times increase in core bandwidth, to 10 gigabits/second
• New wavelength capabilities
Abilene can take you places!

Why is Middleware like underwear?
… everybody needs it but nobody should see it …
Middleware
Middleware is a layer of software between the network and the applications that performs:
• Authentication• Identification• Authorization• Directories
So, Middleware worries about: • Who you are• Where things are• What you are permitted to do
… even across institutional boundaries!
Current Internet2 Efforts
Internet2 community has unique needs and capabilities
• Middleware Architecture Committee for Education
• Early Harvest and Early Adopters• Internet2 Public Key Infrastructure Labs• Shibboleth (inter-campus authentication)• Directories• NSF Middleware Initiative (with EDUCAUSE and SURA)
Does E+2+E+P = ☺ ?
What can I do when things aren’t right?
•Why doesn’t my application work? It did yesterday ….
•Even with high bandwidth network links, the Internet2 community often does not see expected performance.
•It’s harder to figure out who to call, who to blame, what needs to be fixed … all of us “normal” people need help!

How do you solvea problem along a path?
Hey, this is not working right!
The computeris working OK
Talk to the other guys
Everything isAOK
No othercomplaints
The network is lightly loaded
All the lights are green
We don’t see anything wrong
Looks fine
Others are getting in OK
