Internet2 Applications


									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.

What are the"Internet2 Applications"?

These are applications that can make a difference in how we engage in teaching, learning,
and research in higher education. Internet2 applications require advanced networks. That
is, these applications will not run across commercial Internet connections. Internet2
applications require enhanced networking functionality—such as high bandwidth, low
latency (delay), or multicast—not available on our commercial Internet connections.

Disciplines these applications focus on

   A. Internet2 is about everything we do in higher education: in the classroom, the
laboratory, the library, or the dorm.

Applications sources:,

Funding sources for developing applications
Federal Government. Federal agencies and departments, most notably NSF, NASA, the
Department of Energy, and the National Institutes of Health's National Library of

Attributes in the most compelling “killer”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.
3. Using the network as a "backplane" to build network-wide computation and data
    services. (Grid project The objective of the project is to
    enable next generation scientific exploration which requires intensive computation
    and analysis of shared large-scale databases, from hundreds of TeraBytes to
    PetaBytes, across widelydistributed scientific communities. We see these
    requirements emerging in many scientific disciplines, including physics, biology, and
    earth sciences. Such sharing is made complicated by the distributed nature of the
    resources to be used, the distributed nature of the communities, the size of the
    databases and the limited network bandwidth available.
4. Displaying information through virtual reality environments—moving from static
    graphics and images to moving, three-dimensional animations.
We could also use Internet2 connections to collaborate with colleagues around
 the world.

Target application areas
For example, the National Institutes of Health's (NIH) National Library of Medicine has
the largest collection of biomedical information on the planet. The library's mission is to
disseminate this data, which includes all the genetic sequences of the human genome
project. Researchers at the University of Alabama in Birmingham were used to annoying
delays when they accessed biological sequences and genomic databases at the NIH
library, but the UAB's Abilene connection changed all that. Now information goes across
the vBNS-Abilene internetwork at warp speed and screens come up almost immediately.
The high-speed connection also makes it easier for the UAB to maintain and update local
copies of some of the remote data. Gene-sequence analyses that used to arrive on nine
CD-ROMs every other month can now be downloaded over the network in half an hour,
and the local databases can be updated much more frequently.

Telemedicine: During a surgery performed at Ohio State University, Abilene was used to
conference with doctors from other parts of the country. Similarly, 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.

HDTV transmission: remote control of telescopes and electron microscopes; and aligning
massive distributed databases to look for patterns across them.

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.
The computers track the participants and the physical and virtual objects at all locations,
and project them onto stereo-immersive surfaces

Advanced Networks @services
For example, a group of designers will be able to collaborate from remote sites in an
interactive design process. They will be able to manipulate a virtual model starting from
the conceptual design, review and discuss the design at each stage, perform desired
evaluation and simulation, and even finish off the cycle with the production of the
concrete part on the milling machines.
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.

Demo:The participants in the 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).

The area that will provide the widest benefit and largest aggregate use of the Internet2
network capacity is digital video. Video-based applications cover everything from video
conferencing to on-demand content to remote control of microscopes and other
    Video demos:
IVD Network
///In traditional broadcasting, creating communication services for specialized audiences
and content requires challenging trade-off between cost and
quality (the more specialized the content, the higher the overall cost- leading to a bias
toward programming for mass audiences). The advanced
capabilities of Internet2 and IBM technology allow the creation of a foundation for the
IDV Network. iCAIR will work with advanced regional
networks, such as MREN, to develop new communication services for the Network, that
will be scalable nation-wide and worldwide. The Network
will have the potential for providing content through thousands of specialized
information channels for research and education. The demonstration in
San Francisco showcased a number of simulated channels from I2DV stations at seven
major universities (Indiana University, Northwestern
University, Ohio State University, Penn State University, the University of Illinois at
Chicago, the University of Illinois at Urbana/Champaign, and
the University of Minnesota). Channels can broadcast live events, which can be archived,
or stored content selected by the viewer.

Underlying these capabilities will be emerging new Internet technologies that provide for
guarantees of high quality video and audio services,
directory services for managing access to content. Such common services for supporting
applications among Internet2 member institutions will
provide a platform for applications innovation and powerful new functionality.
Distribution of shared materials will be enhanced through the IDV
Network. Other potential projects include establishing policies and procedures for sharing
digital materials, including courses, seminars, informal
lectures, documentaries, such as a common means to license and distribute copyrighted

Latest demos:
Uncompressed Music
The Role of Internet2
  Building on the Pacific NorthWest GigaPoP infrastructure and ResearchChannel's
experiments in
   multi-media, KCMU's streaming of uncompressed audio demonstrates that listeners
may now experience a
   true representation of music via Internet network technologies. Streaming
uncompressed audio over
   Internet networks represents the gold standard in delivering the richest—and the
purest—musical, artistic
   and cultural aural experiences. This work demonstrates how Internet2 networks can
further distribute the
   work of artists in the highest quality possible, enabling more people to experience—
and fully
   appreciate—art, music, and culture the way it is meant to be experienced, as close to
reality as possible.

Virtual Adaptive Learning Architecture: Providing a University Instructional
Materials Repository (

The Virtual Adaptive Learning Architecture, under development at the University of
Arizona, provides a collaborative instructional environment where faculty from multiple
disciplines can easily find, develop, edit and publish multimedia content, and make it
available for use in teaching and learning. This demonstration shows a virtually central
environment consisting of physically distributed RDBMS databases that retrieve media
assets, which are placed in IMS templates. This allows university faculty members to
decrease cycle time in the development of instructional modules and increase the reuse of
materials across courses. The infrastructure for this application includes Oracle's 8i
RDBMS, Oracle InterMedia, Video Server, and many other tools.

Real-Time Tele-Operation of Remote Equipment North Carolina State University
and Georgia Institute of Technology

This demonstration illustrates the joint operation of three network-based remote access
applications: the Tele-vator excavation backhoe, a high-resolution remote microscope,
and the virtual laboratory concept. These applications all share bandwidth and resources;
network-level quality of service is provided via Differentiated Service enabled end-
Tele-vator is a computerized and network-based excavation backhoe that can be remotely
operated over Internet2 networks. Because of its size and potential criticality of operation
(e.g., in hazardous rescue situations) or in remote training, it requires a high-level of
sophisticated two-way feedback. One of the essential feedback mechanisms is providing
adequate depth of vision, which is accomplished via high-definition stereovision.
Stereovision is also essential for investigation of biological samples. Certain microscope
uses, like pathology, where 35mm film resolution of 3000x2000 is absolutely necessary
for diagnosis, requires an astounding 800 MB per second of bandwidth. This
demonstration also illustrates the use of a stereo remote control microscope.
Finally, both the above applications can be used for operational work and for teaching.
This demonstration shows how they can be integrated into a virtual laboratory distance
learning environment.

"Virtual Harlem" at the Desktop

"Virtual Harlem" is a high-end, interactive, re-creation of 1920's Harlem, New York, at
the time of the Harlem Renaissance literary movement. It has been used in specialized
immersive and semi-immersive facilities to give students in American Literature and in
Cultural Studies an enriched understanding of a pivotal period. Multi-site collaborative
experiences have been created previously, but these have required multiple, symmetrical
configurations that executed the application at each site. In contrast, Virtual Harlem uses
a central server to distribute the application, rather than having to replicate it at multiple
locations. The subsequent deployment phase will allow us to achieve much wider
availability of Virtual Harlem through remote support of inexpensive desktop
workstations. Initially the application will be deployed in Harlem itself as the educational
component of a project that is bringing high-speed networking to key locations in

Live Interactive Video Project: Theatre Artists Backstage

Theatre Artists Backstage allows students "backstage" to actually experience the creative
process in the making of a theatrical production. Using Theatre Artists Backstage,
students are able to eavesdrop, dialog, and collaborate with theatre professionals at the
Great Lakes Theater Festival in Cleveland. Through interactive video, students attend
rehearsals, production meetings, visit the scenery and costume shops, and have the
opportunity to speak with directors, designers and actors. In the final phase of the project,
Great Lakes will do a project in collaboration with Cornerstone Theatre of Los Angeles,
in which students at Kent State University will be full participants via Internet2
interactive video. This final product will be performed in May of 2001 at Playhouse
Square in Cleveland. This project is the first humanities course at Kent, and one of only a
few nationwide, to utilize the technologies developed by Internet2 for instruction and
could serve as a valuable proof of concept for other humanities applications.
Digital Libraries
For example, the developer of an application designed to allow students to collect and
analyze data from a scientific instrument on the Internet should have access worked data
sampling tool which recognizes various data protocols, an intelligent plotting window
with a variety of display and scaling features, and a tool for passing sampled data to the
plotting window. With such tools, the developer could concentrate on developing a
networked learning environment incorporating interactive data collection and analysis.

Distributed Instruction

Advanced Network Gateways to Microscopes

The Microscope and Graphic Imaging Center (MAGIC) at CSU Hayward is developing a
network for remote access to visual scientific instruments, including a
Scanning Electron Microscope (SEM) on the Hayward Campus, a confocal microscope
initially to be housed at Hayward, and a Scanning Probe Microscope to be
housed at CSU Fresno. These instruments produce video output that needs to be
transported to distant users who can interact with the instruments via control
protocols. At Hayward, we have already used compressed video over ATM to share live
images from the SEM with San Jose State and with CSU Chancellor's
Office and have controlled the SEM via Internet protocols from off campus.

Advanced BioTelecommunications and BioInformatics Center (ABBC)
Projects at the Advanced BioTelecommunications and BioInformatics center (ABBC) are
experimenting with a wide variety of telemedicine applications. Typical
examples are the ability for physicians at the USC medical complex to examine remote
patients via live video, confer with other physicians, study medical images
transmitted in real time or do all three simultaneously. Current experiments have made
use of an experimental OC-3 ATM network provided under the CALREN
program of Pacific Bell and though T-1 leased lines to remote sites. Access to high speed
Internet service will greatly enhance the scope of the projects to include
other hospitals and clinics and allow experimentation with conferencing capabilities.
Some typical applications of the technology are: remote radiological consultation
(allow time shifting and access to remote experts); retinal image transmission for diabetes
screening and other diagnosis, video consults and interaction with doctors;
access to digital patient records including detailed image records; and access to
supercomputers for precise treatment planning and pharmacology

Modeling and Querying on the content of 3D Macromolecular Datasets
The impact of automatic digital acquisition in microscopes, from Transmission Electron
Microscopes (TEM) to light microscopes, implies that large quantities of data
are being produced.

In order to be useful these datasets need to be properly characterized and organized in a
database enabling scientists to compare their data and find functional
similarities and distinctions among structurally and compositionally similar objects.

In this project, a classification of small macromolecules is being developed as well as
indexes from the specification of the object's properties

Archiving and Analysis of Histological Images
An extensive database of histological sections of various tissues from various
developmental stages has been developed for domestic livestock. Software will be
developed that will allow users access to this histological archive and to conduct image
analysis of their own histological images from remote sites.

CNN) -- Some college music professors are delighted that they can now be in two places
at once -- thanks to Internet2. This "next generation" of the Internet delivers
spectacular quality audio and video over a special network that includes 180
U.S.colleges, high-tech businesses and the federal government. Musicians in a half
dozen cities joined up to show off the technology.

Tele-Immersion (National Tele-immersion Initiative - NTII) will enable users at
geographically distributed sites to collaborate in real time in a shared, simulated
environment as if they were in the same physical room. It is the ultimate synthesis of
networking and media technologies to enhance collaborative environments.
In a tele-immersive environment computers recognize the presence and movements of
individuals and objects, track those individuals and images, and then permit them to be
projected in realistic, multiple, geographically distributed immersive environments on
stereo-immersive surfaces. This requires sampling and resynthesis of the physical
environment as well as the users' faces and bodies, which is a new challenge that will
move the range of emerging technologies, such as scene depth extraction and warp
rendering, to the next level. Tele-immersive environments will therefore facilitate not
only interaction between users themselves but also between users and computer-
generated models. This will require expanding the boundaries of computer vision,
tracking, display, and rendering technologies. As a result, all of this will enable users to
achieve a compelling experience and it will lay the groundwork for a higher degree of the
their inclusion into the entire system.


The benefits of tele-medicine are far-reaching. A specialist in Boston could give advice to
a doctor in rural America 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. Researchers could readily swap and exchange information.

This new paradigm for human-computer interaction falls into the category of the most
advanced network applications and, as such, it is the ultimate technical challenge for
Internet2. Further, a secondary objective is to accelerate the development of better tools
for research and educational collaboration and promote advances in virtual environment
research, which means that this plan will be woven into the fabric of many of the Next
Generation Internet applications.
