1. Internet2

• Internet2 is a not-for-profit consortium, led by
  over 200 US universities, developing and
  deploying advanced network applications and
  technology, accelerating the creation of
  tomorrow's Internet.

3
Internet2s Mission

• Facilitate and coordinate the development,
  deployment, operation, and technology transfer of
  advanced, network-based applications and network
  services to further US leadership in research and
  higher education and accelerate the availability
  of new services and applications on the Internet.

Abilene

• Internet2 backbone network (IP over SONET)
• A project of the University Corporation for
  Advanced Internet Development (UCAID) in
  collaboration with various corporate partners

6
Link Capacities

• 13,000 miles of fiber optic cable, with over
  8,000 miles of interior circuits and another
  5,000 miles of access circuits
• Operates at OC-192 (9.6 gigabits per second) or
  about 354,000 times faster than a typical
  computer modem.

2. Types of Applications

• Internet2 applications require enhanced
  networking functionalitysuch as high bandwidth,
  low latency (delay) and jitter, and multicastnot
  available on our commercial Internet
  connections.

11
Attributes in the Most Compelling
KillerApplications

1. Interactive collaboration environments, where
   users can truly interact with others without the
   barriers of distance.
2. Common access to remote resources, such as
   telescopes and microscopes.

12
Attributes (cont.)

1. Using the network as a "backplane" to build
   network-wide computation and data services
   (Grid computing).
2. Displaying information through virtual reality
   environmentsmoving from static graphics and
   images to moving, three-dimensional animations.

13
3. Example applications

• Grid computing
• Telemedicine
• Astronomy
• Tele-immersion
• Music
• Digital Video
• Tele-Operation of Remote Equipment

14

The Grid project

• Using the network as a "backplane" to build
  network-wide computation and data services.
• It enables scientific exploration, which requires
  intensive computation and analysis of shared
  large-scale databases, from hundreds of TeraBytes
  to PetaBytes, across widely distributed
  scientific communities.

17
Telemedicine

• During a surgery performed at Ohio State
  University, Abilene was used to conference with
  doctors from other parts of the country.
• An MRI machine can scan a patient in one location
  and send the data to a remote supercomputer for
  processing, and then deliver the resulting images
  to a doctor in a third location.

18
Telemedicine (cont.)

• A specialist in Boston could give advice to a
  doctor in rural areas for on-site medical care,
  or even guide that doctor during a surgery. A
  medical student could watch a rare procedure that
  would otherwise be unavailable.

19
Telemedicine (cont.)

• Anatomical and Surgery Simulation over the
  Internet
• The "trainee" could feel the actions and force of
  the instructor's "hand".

20
Radio Astronomy

• Electronic transmission of Very Long Baseline
  Interferometry (e-VLBI) data from the Haystack's
  Westford Observatory and NASA's Goddard
  Geophysical and Astronomical Observatory, which
  were streamed over Internet2's Abilene Network to
  the Haystack correlator at 512 Mbps.
• The live results were displayed in a 3D plot
  (correlation amplitude, differential Doppler,
  differential delay) in Pittsburgh as the data
  were correlated.

22
Tele-immersion

• Tele-immersion creates coordinated, partially
  simulated environments at geographically
  distributed sites so that users can collaborate
  as if they were in the same physical room.

23
National Tele-immersion Initiative - NTII
24
Tele-immersion (cont.)

• In the case of medical applications, such as
  tele-radiology and urgent diagnostics, the
  availability of such technologies in the places
  that are physically inaccessible to specialists
  could potentially save the lives. Off-shore ships
  and oil rigs are good examples of such
  environments.

25
Demo

• The participants in this session were not only
  able to see each other in 3D but they were also
  able to engage in collaborative work, and take
  part in a design process (a simple example of
  interior office design)

26

Music

• College music professors can now be in several
  places at once delivering high-quality audio and
  video via high-speed connections.
• An excerpt of MTT conducting from Miami, an
  orchestra in Cleveland, on October 29th, 2002 New
  World Symphony
• An excerpt from CNN's 'Science and Technology
  Week'
• spotlighting a NWS Internet2 demonstration
  between
• Miami and Atlanta

27
Real-Time Tele-Operation of Remote Equipment
North Carolina State

• Tele-vator is a computerized excavation backhoe
  that can be remotely operated over Internet2.
• Because of its size and potential criticality of
  operations (e.g., in rescue hazardous situations)
  Tele-vator requires a high level of sophisticated
  two-way feedback, including adequate depth of
  vision provided via high-definition stereovision.
  
• Guaranteed Quality-of-Service (QoS) such as
  network bandwith, latency control, and jitter
  control are essential to insure the quality of
  the 3D image, audio, and equipment control
  channels.

28
nanoManipulator Seeing and Touching Molecules

• Scanning-probe microscopes allow the
  investigation and manipulation of surfaces down
  to the atomic scale. The nanoManipulator (nM)
  system provides an improved, natural interface to
  SPMs, including Scanning Tunneling Microscopes
  and Atomic Force Microscopes. The nM couples the
  microscope to a virtual-reality interface that
  gives the scientist virtual telepresence on the
  surface, scaled by a factor of about a million to
  one.

• The goal is to evaluate and measure the
  performance of various QoS solutions through
  active participation of the I2 Application QoS
  Working Group and other I2 partners.
