Fall 2003 Internet2 Member Meeting
Poster Sessions
The following Poster Sessions were held during the
Fall 2003 Internet2 Member Meeting
Multicast over an Intracontinental
Area
ANSP/LARC/EPUSP
Tereza Cristina Carvalho
This presentation shows the results of some cooperation
experiments that have been developed
between American and Brazilian research centers
and universities in the Multicast transmission arena
over Internet2. The purpose was to create an international
multicast path that in the short run will
allow the transmission of high-quality video
among these institutions. It will include a 24 x 7 x
365 exchange of educative and informative digital
videos. As not all the routers in the path between
U.S. and Brazil support multicast transmission, the
traffic generated in U.S. or Brazil has to be encapsulated
in GRE tunnels. These tunnels create a
point-to-point virtual link between the remote
endpoints. It interconnects GigabitEthernet, ATM
(Asynchronous Transfer Mode) and POS (Packet
over SONET) subnets. As result, it is being created
an intracontinental super highway for unicast and
multicast traffic, assuring end-to-end quality of
service and supporting not only Digital Video
transmission but also HDTV transmission. This
experiment involved the following Internet2 participants:
University of São Paulo, ANSP (Advanced
Network of State of São Paulo), FIU (Florida
International University), utilizing Global Crossing
infrastructure and the Abilene network in the U.S.
The Converged Network of the Future
ENTERASYS NETWORKS, INC.
Anja A. Allen
With the emergence of protocols like SIP, the
opportunities for the development of new and
innovative applications for education are without
limits. The implementation of multi-media applications
will become common in educational and
business organizations. New technologies such as
simulation-enabled e-learning will be made possible
by the increased convergence of voice, data, and
images. But what about the network where all these
new services and applications will be implemented?
Simple QoS services will not suffice. The converged
network of the future will have a never-before-seen
level of complexity, and will need to be more secure
than ever as more and more organizations depend
on an increasing number of applications. New concepts
such as identity and location will have to be
introduced to master the challenges of tomorrow’s
converged networks.
Deployment of a High-Speed Metropolitan
Network to Share Medical Information
HEART INSTITUTE (InCor) Sao Paulo
Marco Gutierrez
The delivery of health care and sharing of medical
information over a distance using telecommunication
systems involve a diverse set of clinical,
educational and research applications and an
equally diverse set of e-technologies. The technological
basis and the practical issues are highly
variable from one clinical application to another.
Moreover, if the information to be exchanged
involves images, a special problem in cardiology is
how to handle full motion video echocardiograms
and cine angiograms. In the metropolitan area of
São Paulo, Brazil a set of Research Institutions have
been working in a project as part of a national
effort to provide a very high performance backbone
using ATM links. This project is based on image
servers, which can store, send and receive medical
images, as well as a set of visualization applications,
which can communicate with the servers using
DICOM 3.0 protocol. A middleware CORBA was
developed to provide user authentication and validation
through a public domain Directory Server
using LDAP version 3 protocol. The integration of
the existing corporate TCP/IP networks with the
ATM infra-structure was performed by a number
of Linux boxes, which implements the Classical IP
over ATM mechanism and the IPSec protocol.
The Internet2 Commons Videoconferencing Service via H.323
INTERNET2
Jonathan Tyman Poster will describe the current videoconferencing
offering of “The Commons” that is being demonstrated
at the meeting. Complete information will
be available about current subscription options as
well as future plans. Our view is that growing the
future of intercollegiate and corporate research collaboration
has a collective component perfectly
suited to Internet2.
XML-Based Signaling for an On Demand/Scheduled Wavelength Path Service
JAPAN TELECOM
Toshikatsu Kanda, Hideki Yoshii The prototype of an on demand/scheduled wavelength
path service was developed using GMPLS
and security technologies. This prototype permits
customers to establish wavelength paths securely
through the Web with zero touch operation.
GMPLS is used for controlling the wavelength path
network and PKI and biometrics are used for customer
authentication. About the next generation
network model, the separated networking functions
model, which consists of control plane, data plane,
and management plane, is proposed. Under this
circumstance, a security issue among different
planes as well as UNI/NNI and a lambda resource
management issue have come up. To tackle these
issues, we take the XML-based management
approach and propose the XML-based Signaling
(XBS). First, the XBS defines message formats and
message sequences for on demand/scheduled wavelength
path service requests/responses (signaling)
at UNI/NNI. Second, the XBS carries management
information for lambda resource management.
Then this lambda resource management is generalized
to the XML-based network management with
other XML-based management activities such as
XML MIB and Web Services. The XBS provides a
secure management information exchange including
request/response messages. Authentication is
based on XML signature and PKI technologies.
About the snooping threat, secure transport
protocols such as HTTPS are used.
Polycom Video Error Correction (PVEC) Technology
POLYCOM WORLDWIDE
Phil Marechal
The information streams in video conferencing are
UDP packets for audio and video. Currently there
is no QOS on the public Internet, and you can have
out of sequence packets and lost packets. Because
UDP does not allow for packet retransmission you
can have a video stream with missing information.
Polycom has developed a method of application
QOS called PVEC. The poster will describe how the
PVEC technology works and can improve audio
and video conferencing when there is packet loss.
This technology is also being submitted to the ITUT
for a future standards version.
Advanced Applications in Drug Discovery and Multimedia Medical Education
PROUS SCIENCE
Jesus Salillas, Artur Serra
The session will present advanced applications
involving a collaborative international effort for
large-scale data mining for drug discovery and prediction
purposes, as well as an Internet2 Medical
Education Channel with advanced multimedia
streaming features. Innovative MPEG-7 speech
recognition and video retrieval tools allow for the
browsing of large quantities of educational video
and for the integration with scientific data, such
as searchable chemical structures and genome
information.
An Integrated Wireless Messaging Architecture in
the Internet and Mobile Telecommunication
Network Environment
TANET2—NATIONAL CENTER FOR HIGHPERFORMANCE COMPUTING,
NATIONAL TAIWAN UNIVERSITY
Chiping Chan, Ching-Heng Ku, Zsehong Tsai,
Yung-Chi Yang
A new wireless messaging architecture based on the
integrated WLAN/GPRS multi-mode multi-messaging
system has been proposed. This architecture,
built on the Internet and the mobile telecommunication
network environment, delivers the
multimedia object and the short message and
brings the corresponding advantage in the highbandwidth
and the real-time delivery, respectively,
in this integrated system.When an emergency
event occurs, a quick message delivery channel will
send messages to relative persons. The notice message
will be sent using the short message service
(SMS), and the content of the event downloaded
through the Internet by the receiver will be stored
in the multimedia object database. To achieve the
above result, we use the object storage and retrieval
techniques, and propose a phone number converting
method, the specific message format, and the
short message delivery technique in this system.
The short message delivery will be achieved using
the WLAN/GPRS card or the ISP service as sender.
The message object in this scenario contains
text/image/video/audio etc. In conclusion, the proposed
system can achieve the real-time, guaranteed,
and confirmed multimedia message delivery. This
work is targeted at the enterprise, government, and
campus users, and developed under the National
Telecommunication Program of the National
Science Council (NSC) in Taiwan.
Network Security for Higher Education-Intrusion
Prevention and Anti-Piracy
TIPPINGPOINT TECHNOLOGIES
Tim Wickham
This session will explore the unique security issues
that face today’s universities. Campuses are
required to provide open access to the network for
students, often rendering the network vulnerable to
cyber attacks. Campuses are also dealing with an
increase in peer-to-peer applications, and are held
liable when students download copyrighted information.
Today’s breakthrough security products are
addressing these issues by performing total traffic
inspection. Intrusion prevention technology is able
to block attacks and P2P traffic.
Collaborative Learning in a Virtual Reality
Environment
UFRGS/RNP2
Liane Tarouco
3-D virtual environments for online learning may
be considered a second generation of software for
distance learning support and allows learning by
doing. The construction of these environments
with both proprietary and open technologies is the
object of this proposal.Methodology and processes
used in the creation of 3-D objects and in the
development of a collaborative learning environment
software using virtual reality are the focus of
the proposed session.
