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.
2
Internet2’s 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
5
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.

Types of Applications
Internet2 applications require enhanced
networking functionality—such as high
bandwidth, low latency (delay) and jitter, and
multicast—not available on our commercial
Internet connections.
10
Attributes in the Most Compelling
Applications
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.
11
Attributes (cont.)
3. Using the network as a "backplane" to
build network-wide computation and data
services (Grid computing).
4. Displaying information through virtual
reality environments—moving from static
graphics and images to moving, threedimensional animations.

Example applications
• Grid computing
• Telemedicine
• Astronomy
• Tele-immersion
• Music
• Digital Video
• Tele-Operation of Remote Equipment
13
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.

16
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.
17
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.

18
Telemedicine (cont.)
• Anatomical and Surgery Simulation over
the Internet
• The "trainee" could feel the actions and
force of the instructor's "hand".
19
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.
20
21
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.
22
National Tele-immersion Initiative NTII
23
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.
24
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)
25
Music
•College music professors can now be in
several places at once delivering highquality audio and video via high-speed
connections.

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 highdefinition 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.

nanoManipulator: Seeing and Touching
Molecules (6 min)
Scanning-probe microscopes (SPMs) allow the
investigation and manipulation of surfaces down to
the atomic scale. The nano Manipulator (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.
