Description:
This demonstration will provide participants with a hands-on opportunity to
work with the Immersive Segmentation application. This application, which is
a part of the Stanford HAVnet Project, allows remotely separated users to collaboratively
work at visualizing and segmenting structures in volumetric data sets such
as the Visible Human. The client interface is stereoscopically immersive and
uses a PHANTOM haptic device to both track the user's position and provide
force feedback for anatomical structures as they are segmented and visualized.
The system provides the user with the ability to interactively direct the application
of high-cost segmentation algorithms. Several segmentation techniques are available
to the user including the ability to interactively generate surface mesh representations
of segmented structures. Haptic feedback not only provides the user with a
sense of touch for the segmented anatomical structures, but is also used to
control the progress of the segmentation algorithms themselves. The server
supports multiple clients with the visualization data stream transported either
by unicast udp or multicast. In addition to the visualization data stream,
the server also computes and transports a data stream to the
client that is used for constructing haptic feedback.
Role of Internet2:
By virtue of its tightly-coupled interaction between multiple
users and remote computation through multiple data streams, this application
requires the predictable bandwidth and latency characteristics of Internet2
advanced networks.

Description:
Peakflow SP provides a comprehensive solution delivering powerful network traffic
analysis and secure, reliable communications across the entire network. Peakflow
SP's Traffic and Routing module transforms network operations through its
complete view of network-wide traffic and routing data. With real-time visibility
into all parts of the network, network operators can produce detailed usage reports
by department, noting allowance for bill back and providing for accurate resource
planning. Peakflow SP's Infrastructure Security module proactively detects and
mitigates network-wide anomalies such as distributed denial of service (DDoS)
attacks and zero-day worms. This provides network operators with the information
they need to quickly resolve these threats before their network is affected,
service suffers, or customers complain.
Role of Internet2:
The development and initial proving ground for Arbor Network's Peakflow solution
was founded on a three-year collaborative research effort with Internet2 affiliate
member and Abilene connector Merit Network, Inc. and Internet2 member University
of Michigan.
Over time, Peakflow
has been deployed across a number of Internet2 member networks, in the Abilene
Network, and at several other leading universities. Arbor Network's successful
collaboration as an Internet2 corporate sponsor has strengthened the community's
ongoing efforts to improve security.

Description:
The DREAMS™ project integrates intelligent communication devices in ground-based
ambulance services in rural Texas that allow trauma and other medical specialists
to treat patients more quickly by providing a “virtual” presence of a physician
on the battlefield or at the emergency scene. The goal of these ambulance systems
is to improve the diagnosis and treatment of critically injured people in the
field by expediting their access to medical experts at trauma centers through
the utilization of various modern communication and monitoring devices.
With
the expert guidance of the online physician, the presence of a virtual physician
has an immediate positive impact on patient care. The DREAMS project demonstrates
that the application of telecommunication and other advanced technologies
will decrease the interval between the incident of injury and the initiation
of definitive tertiary care. Advanced telecommunication technologies will
also permit the direction of appropriate interventions that would otherwise
be delayed until the patient reaches the treating facility.
In conventional
warfare, hemorrhage is the leading cause of death following the occurrence
of an injury. By transmitting real-time physiologic data and video display
from the battlefield to a medical control center for physician interpretation,
the opportunity for initiating appropriate lifesaving procedures and definitive
therapies in a timely manner can significantly impact patient survival. With
the application of telecommunication technology, new protocols can be developed
that will further advance the improved outcome for various specific traumatic
injuries. The real-world trauma environment in Houston, Texas, provides the
military with the ideal testbed for developing and perfecting procedures
to support missions of disaster relief, both domestically and abroad.
We will be demonstrating four of the DREAMS components: Civilian Ambulance,
Military Ambulance (HMMWV), Ku band "Mobile" terminal, and Deployable
Telemedicine System (DTS).
- The civilian ambulance is equipped with multiple
computers, cameras, and various medical equipment. Electronic health records,
patient data bases, video and other data compression, and EMT support
databases are available. Multiple wireless and wired LANs as well as 8
cell phones operating in parallel provide connectivity. The
vehicle can also have the Ku band satellite terminal mounted on board.
- The
HMMWV has a subset of the civilian equipment integrated into a full mil-spec
four litter, armored vehicle. Military radios are supported but will
not be present.
- The satellite terminal test vehicle is a standard civilian
ambulance with DREAMS upgrades which is used to do only satellite performance
testing in parallel with human subjects field testing on the other vehicles.
- The DTS is the DREAMS software and hardware package from the ambulance
redesigned and repackaged to be portable/transportable for drop-in or carry-in
to a disaster scene. It can be used as a triage focus or aid station, among
other uses.
Role of Internet2:
Internet2 advanced networks have the potential to increase DREAMS
capabilities in emergency situations, especially where natural or other large-scale
disasters disrupt communications in a region. A large majority of the
nation's medical teaching and research facilities are now connected to Internet2
advanced networks. Real
time large scale or national emergency medical information could be delivered
to any or all of these institutions much faster and more effectively over Internet2
than via the commodity Internet. The
DREAMS mobile terminal can be configured to do this on the move.

Description:
This demonstration will use the scenario of a surgical instructor,
located remotely in Canberra, Australia, teaching a surgical trainee or student,
located at the Internet2 Member Meeting, about a particular surgical procedure. Delegates
at the Internet2 demonstration location will be able to interact with the remote
instructor manipulating and feeling the models that are being used as part
of the teaching. Others may choose to observe in the style of an audience watching
a surgical master-class. The concepts being explored will include:
- The student and instructor engaged in a dialogue, both with words and with
actions, mediated by virtual tools, objects and interaction interfaces
- The audience observing the dialogue and the subjects of the dialogue
- The geographical distance between instructor and student/audience (actually
approximately 8,500 miles) as no barrier to successful interaction
The surgical instructor will lead the student through the simulated procedure,
while immersed in the 3D scene comprising liver, stomach, gall bladder, kidneys,
and other abdominal organs. The system will continuously transmit incremental
changes in the 3D model (anatomy, instruments, pointers, and annotation) between
Canberra and Austin keeping all movable components, as well as the users' instruments,
synchronized with each other. Both participants can simultaneously grasp pliable
body organs, cut tissue, clip and cut ducts, and at the same time feel the
actions and forces provided by each other across the Pacific. The instructor
can grasp the student's tool, and guide it to the correct part of the anatomy,
helping them to grip and extend the attached ducts to apply the required tension
for clipping. It is possible for each site to independently zoom and
pan the viewpoint, as well as to lock the views together to jointly study the
scene.
Both participants are able to draw three-dimensional annotation in the virtual
scene while discussing the anatomy, as well as draw diagrams on a virtual white
board and annotate a virtual medical scan viewer. This permits detailed
discussion about the techniques required in the gall bladder removal operation. Each
is able to point and sketch questions and answers, adding to the flow of information
between instructor and student.
A virtual video player embedded in a separate part of the scene, allows the
participants to remain immersed in the virtual environment while they view
a pre-recorded video of real surgery. Each participant can pause the video
and draw on the virtual screen while discussing the operation. The virtual
video players at each end of the network connection are synchronized so that
each participant sees the same video frames. This video feature helps
to bridge the gap between the diagrammatic, abstract presentation of the surgical
procedure delivered using the virtual anatomical models and the reality of
actual surgery. Its role parallels the blend of streaming surgical video,
static anatomical images and off-line discussion that was presented at the California
Orthopaedic Research Network (CORN) demonstration at the Fall
2002 Internet2 Member Meeting (Dev et al, 2004).
Role of Internet2:
Internet2 advanced networks provide the low latency for haptic interaction,
low latency to keep dynamic models synchronized at both sites, and high bandwidth
for high definition videoconferencing that are required by this application.

Description:
The Internet2 Commons will demonstrate the many different tools that
researchers and educators use for engaging in collaborations over advanced
networks. The Internet2 Commons and its partners will preview a proposed “hosting
environment” for near production-ready applications which will drive adoption
of appropriate technologies while promoting interoperable development. These
technologies offer full-spectrum, real-time communications—from presence, chat,
voice, and video—to sharing of presentations, large data sets, and computer
simulations through a variety of channels and, ultimately, the one that fits
your requirements and capabilities best.
Role of Internet2:
Real-time video is the coal miner’s canary for the network, in that it
only works when the network environment is healthy. Internet2 advanced networks
provide the bandwidth necessary for large-scale deployment of reliable videoconferencing.
Internet2 also provides the credible, neutral vetting necessary for broad integration
of federation-wide collaboration tools.

Mystic Aquarium and Institute for Exploration
Description:
Video over networks has been around for some time. From legacy
videoconference systems to high-quality, MPEG-2 distance learning and streaming
systems—video has been an important part of Internet2 since its
beginning.
But virtually all video to date has been flat, single-dimension. These systems
seek to digitally emulate what already exists: conventional television. In
this demonstration, VBrick Systems will show live 3D video, transmitted
from Mystic Aquarium in Connecticut and from VBrick Systems, to the conference
in Austin, Texas. Live
3D video provides a truly immersive experience, giving the viewer much more
information than conventional one-dimensional displays and allowing them to
truly experience the remote locations, not just "see it".
This demonstration does not utilize artificial, computer-generated images,
but rather live video displayed on a large projection screen in full 30 frames-per-second
and with high-quality, stereo audio. This live 3D demonstration will
provide high definition quality video and will use VBrick Systems MPEG-2 appliances
to deliver the video via IP multicast over Internet2 advanced networks.
Role of Internet2:
Internet2 provides the bandwidth required to transport DVD quality
video over vast distances in real-time. This 3D set-up we are demonstrating
can easily be duplicated at any venue that has access to advanced networks. It
is ideal for distance learning where the 3D video enhances the educational
process. Typical applications include science experiments, virtual fieldtrips,
and arts performances.

Description:
The Logistical Session Layer (LSL) is a protocol and middleware system
for improving performance and functionality in high-bandwidth networks. By
utilizing short-term storage "in" the network, end-to-end throughput
can be increased. Additionally, LSL enables a variety of new functionality
for distributed applications. We will demonstrate the ways in which applications
can be made to use this system both as a modification to existing binaries
and via small source code changes. The LSL infrastructure is going to be selectively
deployed on Internet2's Abilene Network over the coming months.
Role of Internet2:
The Logistical Session Layer is a system that improves the throughput of long
distance TCP transfers across advanced networks such as Abilene. It also provides
an infrastructure that enables a wide range of emerging advanced functionality,
and thus serves the needs of the Internet2 community.

Description:
The use of Logistical Networking (LN) technology by the Internet2
community has been growing rapidly for the past year, amounting to almost 1%
(3.3TB) of traffic on the Abilene Network during the last week of
May 2004. Both end users and application developers are finding that this revolutionary
synthesis of shared storage and high speed networking makes it easy for them
to get outstanding performance (10s-100s Mbps) for content distribution,
advanced multimedia and collaborative applications of all types. Moreover,
it does so without sacrificing either flexibility or ease of use. Our live,
interactive demonstrations will make the reasons for this enthusiastic user
response evident. The LN
tools and applications to be shown include the following:
LoDN — The Logistical Distribution Network (LoDN, or “low down”) is
a content distribution service that allows Internet2 users to store, publish,
and access content at high performance on the global LN infrastructure using
a Web-based directory interface and simple java enabled tools. Currently offered
as a service by University of Tennessee's LoCI Lab, LoDN is already in daily
use on Internet2 for the high speed delivery of hundreds of gigabytes of Linux
ISOs and large scientific data files at high performance. When the
LoDN server software is published later in 2004, other individuals and groups
will be able to set up LoDN services of their own, leveraging the same LN
infrastructure and the same auto-installing Java client to serve their users.
IBPvo — Personal video recording meets Internet2 in this
experimental application. IBPvo shows how LN technology, which is based
on the Internet Backplane Protocol (IBP), can be used for the recording and
flexible delivery of video content. Obvious application areas within the
Internet2 community include distance education and telemedicine, especially
in the wide area or to large, highly distributed communities. LN technology
is being used for educational video distribution across a large number of
sites on the Brazilian research network, Rede Nacional de Pesquisa (RNP),
for example.
LoRS — The Logistical Runtime System (LoRS) is a suite of software tools for
more sophisticated users, content publishers, and developers. It provides
more fine grained control over the use of the LN infrastructure, supports
the detailed visualization of how content is distributed, supports sophisticated
end-to-end services, such as automatic data compression/decompression and
error encoding for more efficient fault tolerance, and comes with a complete
API that allows application developers to exploit the full range of power
of LN technology.
Role of Internet2:
LN infrastructure is distributed across Internet2 institutions, at several sites
closely connected to the backbone, and on high performance research networks
world wide. There are currently 359 public IBP servers in 25 countries and 32
American states, with 30+TB of storage available for use. The main beneficiaries
of LN technology are Internet2 users and application communities, because it
enables them to easily get the 10s-100s Mbps out of their high speed network
connections.

Description:
The MusicPath software, created at Acadia University, has enabled the
connection of digital acoustic pianos over IP. While previous projects
have successfully used videoconferencing for music, this project actually enables
the remote piano keys and pedals to be controlled from a distance. Piano pedagogues
listen to the true acoustic performance, not amplified sound. Since the fall
of 2003, a 12 year old piano prodigy in remote Nova Scotia has been receiving
lessons from a piano pedagogue in metro Toronto. In
addition, some music examinations and interactive classes have been conducted
over this IP connection.
Media interest in MusicPath continues. Both TechTV and the New
York Times have been excited by the live demonstrations. Oscar Peterson,
internationally renowned Jazz pianist, calls MusicPath a "breakthrough in music." MusicPath
was developed at Acadia University by Jim Diamond and Christoph Both; Karen Wilder
is MusicPath Project Manager.
Role of Internet2:
The Canadian
CA*net4 high speed network enabled the MusicPath research and the subsequent
music lessons. Without the software and the
IP network, the lessons could only be conducted by travelling from rural Nova
Scotia to metro Toronto by car and plane. Because of the interconnection of
Internet2 and CA*net4, we are now free to conduct music lessons or give piano
performances between any locations where the network travels.

Description:
Tools to enhance network performance are not a novel concept, yet
many users still struggle to achieve the full potential of their networks.
While consulting the advice of a network engineer is the ideal solution, it
is not always a possibility. Therefore, users can now consult "the Advisor."
Developed by the NLANR Distributed Applications Support Team, the Advisor is
a simple, yet sophisticated, open source application that measures, displays,
and analyzes network metrics. It uses existing diagnostic tools such as ping,
traceroute, Iperf, and Web100 and integrates them into a common framework.
This framework attempts to emulate a networking expert, and allows users to
troubleshoot their own networking problems. Additional tools and analyses
are simple to add. Additionally, the Advisor is well designed in that specific
components that expose performance data may be separated, and customized,
or integrated into other applications.
The Network Performance Advisor has advanced significantly over the last year
and now includes a stable Performance Data Collector that utilizes the Global
Grid Forum Network Measurement Schema, a more intelligent Analysis Engine, a
Historical Data Archiver, and improved GUI. Attendees at this demo will see
all components in action as we run controlled performance tests between the
demo location and other remote locations.
Role of Internet2:
Over the last few years, the NLANR/DAST Advisor project has worked closely with
the Internet2 End-to-End Performance Initiative Performance Environment System
(piPEs)
project. Both projects
are active participants in the GGF Network Measurement Working Group, which
is responsible for the Network Measurement XML schemas. Using a common schema
to represent network metrics, the two frameworks can easily share measurement
data. Therefore, the Advisor is capable of utilizing and displaying data
collected by piPEs. We plan to make use of the Internet2 piPEs data in our analysis
of the end-to-end path.

Description:
In the final year of its cooperative agreement, the NMI Integration
Testbed Program is further formalizing its evaluation of NMI Grid components
and related integrating enterprise middleware. This will be accomplished by
building an NMI Testbed GRID and related investigative activities to achieve
the following broad objectives:
- Provide a mechanism for testbed sites to explore grid capability with researchers
and faculty.
- Identify, address, and resolve unaddressed cross-campus authentication
for inter-institutional grids.
- Expand evaluation and real life usage of NMI components related to campus
enterprise infrastructure.
- Provide NMI Sites with a foundation from which to propose and secure funding
for additional development.
The demonstration will include using local credentials (UMich using its enterprise
Kerberos; UAB using its enterprise BlazerID) linked to campus enterprise CA
certificates to access grid based resources. A NMI Testbed Grid BridgeCA (hosted
at UVA, with UAB, TACC and others cross certified) will allow the use of local
authoritative enterprise credentials to access grid resources external to the
local campus. Sites will demonstrate several NMI Testbed Grid portals, based
on OGCE and Ganglia, as a way to view resources, submit jobs, monitor activity,
and retrieve results. A bioinformatics application for genome sequence alignment
(developed at GSU and tested on UAB grid resources) will demonstrate using
grid middleware tools to provide improved performance for genome alignment.
Grid-enabled applications in production at UAH & TACC will also be demonstrated.
The interoperation of these various resources and components will demonstrate
the technical solutions needed for grid-based resources and grid-enabled applications,
as well as serving to highlight some of the policy issues that must be considered.
Role of Internet2:
The NSF cooperative agreement, under which this work is funded, is a partnership
between Internet2, EDUCAUSE and SURA. The Internet2
Middleware Initiative has also been instrumental in influencing this
work through the fostering middleware investigations and establishing standards-based,
open solutions for inter-organizational collaboration and research computing.
