Objectives: We have established a medical network system with high-quality moving image
on a super broad-banded Internet between Korea and Japan since February 2003.
Teleconference or demonstration of live surgery using DVTS was revolutionary
in medical fields. As our activity is known at various places, there have been
strong demands to join our project from many countries.
In order to promote our system to whole Asia-Pacific regions, it is essential for
both medical and engineering people get together on site and discuss our next strategy.
Medical staffs need to talk on institutions to be connected and their interesting
contents on coming teleconferenes. Engineers are expected to give their
practical comments to medical team on possibility of infrastructural
as well as technical issues.
This system is unquestionably useful for exchanging views in medicine.
The purpose of this session is to share the opinions to work systemically to expand the current project.

Objectives: We have established a medical network in Asia-Pacific area with high-quality
moving image on a super broad-banded internet line since February 2003.
Broadcasting real-time surgery and teleconference with medical-quality videos
with Digital Video Transport System (DVTS) were so useful to learn surgical
techniques and other medical procedures beyond borders. We have conducted 22
events in categories of teleconference (8 times), live transmission of medical
procedure (7 times), and remote attendance to scientific medical meetings (7 times)
until October 2004. We had teleconferences among 3 countries in APAN-Hawaii in January 2004
(Japan, Korea and USA), and in APAN-Cairns in July 2004 (Japan, Korea and Australia).
There have been no serious transmission/ ethical problems so far. We always have, at least,
one trial as of network technique and content in every event. With these experiences and
current achievements, we hope to extend this advanced network system to whole Asia-Pacific
countries to share medical skills and knowledge.

Session description:
Performing regular analysis of the end-to-end path across domains creates
a normal operational mode where network operators and end-users can easily
determine network capabilities and restrictions. In turn, this will
significantly improve the likelihood that advanced Internet applications
operate at peak performance and thereby advance the productivity of researchers.
The Internet2 End-to-End Performance Initiative (E2Epi) is establishing
a performance measurement infrastructure across and beyond university
campuses and labs. International collaboration has already generated
testing points in Europe, Asia and Latin America allowing for performance
monitoring across multiple, international domains. In Europe, the
GEANT2 project is deploying similar performance measurement and monitoring
infrastructures. And in Asia, APAN and KREONET have deployed measurement
points compatible with the Internet2 Performance Initiative Performance
Environment Software (piPEs).
The latest piPEs-related project developments will be presented, including
alpha release of the piPEs visualization package and alpha release of
the piPEs Performance Measurement Domain software package. In addition,
case studies will be explored, suggesting ways in which the measurement
infrastructure can be used. Special emphasis will be on American/European
collaboration to create measurement frameworks for transatlantic partial
path analysis as well as multi-domain measurement activities and inter-connectivity
with a number of countries in Asia and Latin America. Speakers from
each of these regions will talk about their deployments and ways in which
they are working together to make these deployments inter-operable.
Speakers:
1. Masaki Hirabaru:"Advanced
TCP Performance Measurement with BWCTL"
It is important
to measure TCP performance before transferring huge
data between long distant places over Internet. Combining BWCTL with
Web100 enables us to examine detailed TCP dynamic behavior and helps
us to identify the bottleneck of performance. A case study of BWCTL
deployment in e-VLBI as well as Tokyo NOC will be presented.
2. Minki Noh: E2E
performancemeasurement In KREONET
Within the context
of KREONET (National Research Network of Rep. Korea) we will take a more
in depth look at
existing measurement programs (AMP, Netflow, NDT, Network performance
tester, etc.) Special attention will be given to the players involved,
how the services are used, and the operation policies in place.
3. Matt Zekauskas:
Internet2
Activities Toward aGlobal Measurement Infrastructure
Monitoring performance
across multiple, international domains is made possible through the ongoing
collaborative efforts of Internet2, GEANT2 JRA1, GGF NMWG, and other groups.

HDTV
& Access Grid Session
Time: 2005.1.25 (tue)
9:00-12:30
Place: Room F
(original proposal)

Organizer/Chair: JongWon Kim (GIST) |
#1. HDTV & Access Grid session 1 Objective: This AG and HDTV session is designed to provide attendees
with an opportunity to discuss the latest development on the enhanced
media support for AG (Access Grid). In this session, several on-going
efforts on the high-quality media services for AG will be presented
and discussed.
Speakers:
- AGPager
-- Advanced Display Management (speaker: Tokyo Institute of Technology
Hiroyuki Komatsu)
Abstract : The Access Grid uses many windows
such as video windows, presentation slides, and control panels.
To control those windows, an operator has to move, resize and iconify
each windows separately at the present. AGPager provides an easy
window manipulation GUI as well as an automatic window layout
system under a specified layout rule. This talk will present the
usage of AGPager, the outline of the implementation, and the goal.
- MPEG4 codec
for Access Grid (speaker: NCHC Barz Hsu)
Abstract
: Access Grid are solutions most directly targeted to large and
complecollaborations. Video and audio communications are doubtless
the most components in Access Grid. The mbone tools used in Access
Gird includes "vic" for video and "rat" for
audio. However, the video codecs inside vic are somewhat out-of-date
and lack of exhaustive optimization. For these reasons, we have
tried to incorporate MPEG4 codec into vic and adopt several
video filters such as deinterlacing and interpolation filters to
provide better visual quality. For the source of NTSC resolution
(720x480) with 20 frames per second, the typical bit rate of MPEG4
codec is only 1 Mb/sec and the PSNR value is about 40 dB. Furthmore,
we also paid attentation on minimizing the encoding latency and
the ability of error resilience. In conclusion, modified vic indeed
provides a better "sense of presence" than before and
runs very efficiently. Thus, Access Grid can perform a large scale
and high quality video conferenceing.
- AGconnect:
Toward better connectivity for the AG (GIST Namgon Kim and JongWon Kim)
Abstract:
Access Grid (AG) uses multicast to deliver multimedia data. By using
multicast, AG can achieve bandwidth efficiency. But multicast is
an obstacle for users in multicast-disabled network. To solve
this problem, AG provides multicast bridge for users in unicast
network. Multicast bridge only treats users in unicast network.
However, there are many kinds of AG-disabled users. For example,
users behind firewall, users with insufficient network capacity
and users with weak system performance can't use AG efficiently.
Our goal is to provide connectivity to AG for these users. As one
effort for this, we modified QuickBridge to support AG with High-Quality
Video. In this talk, we will show the structure of modified AG to
support connectivity solution for AG with High-Quality Video.
|
#2. HDTV & Access Grid session 2
Objective : This HDTV session is designed to provide attendees
with an opportunity to discuss the latest development around the
network-based delivery of HD (high-definition) video technology.
Aiming to provide immersive experience to end users with HD quality
video, lots of efforts are taking place to enable HD video contents
over high-speed research networks. In this session, several on-going
efforts on HD video delivery will be presented and discussed.
Speakers:
- Full
rate Uncompressed HDTV Transport: Experiences and Implementation
[Remote Presentation]
(speaker: USC ISI Ladan Gharai and University of Glasgow
Colin Perkins) Abstract:In this talk we present the architecture and implementation
of our full-rate UltraGrid nodes capable of sending and receiving
up to 1.485 Gbps of uncompressed HDTV content. Previously, UltraGrid
nodes were limited to sending and receiving (close to) 1 Gbps of sub-sampled
HDTV content due to hardware limitations. However, the proliferation
of
PCI-X technology and the advent of 10 Gbps NICs, has removed all hardware
barriers to building full-rate UltraGrid nodes. We discuss
the technical challenges of transporting full-rate HDTV from the network
and end-system's point of view.
- AARNet
and ResearchChannel TransPacific HD video (speaker: AARNet Andrew Howard)
Abstract: Over the past six months AARNet (Australia's
Academic and Research Network) and ResearchChannel have collaborated
on a number of projects to develop compressed and uncompressed High
Definition video conferencing. Following the demonstration at the
Cairns APAN meeting the first transpacific uncompressed HD video
conference was operated for four days during the SuperComputing
2004 event between Canberra (Australia), Pittsburgh and Seattle
(USA) using the SXTransport network. Compressed HD video between
Australia and Hawaii was demonstraited at the PTC05 conference.
The demonstrations were built from "off the shelf" hardware
with software developed by ResearchChannel.
- Implementation
of Low-Cost Stereo High-Definition Video Delivery System (speaker:
GIST Kiyoung Lee and JongWon Kim)
Abstract: In GIST, we has implemented
a stereoscopic high-definition video delivery system using modified
VideoLAN S/W. We are using two JVC HDV cameras(JVC GR-HD1). The
format of this camera is MPEG-2 TS at MP@HL and the bandwidth is
19.2Mbps from each camera. The total bandwidth of this system is
38.4Mbps with two 19.2Mbps MPEG-2 TS streams. In the sending part
two streams from each camera are muxed and sent to the client. The
client receives these streams, then each streams are decoded after
demuxing process. Using 3D display devices end users can feel the
HD stereo video. (For more detail, please contact hdtv@netmedia.gist.ac.kr)

Session Introduction:
Advanced
networks have become one of the cornerstones of collaboration for research
and education in the 21st century as the commercial Internet has been
unable to support the bandwidth intensive and other advanced needs of
those constituencies. In many ways, the technologies developed and deployed
in these advanced networks are leading the way to the next generation
of the commercial Internet, such as with early deployment of 10Gbps circuits,
multicast deployment across autonomous systems and advances in user control
of lightpaths. Examples are multiplying of cross-sector and cross-boundary
collaborations in the creation of those advanced networks. The challenge
will be to insure that these national and multi-national efforts interoperate
seamlessly.

Session
Plan:
1: Malcolm Read
Executive Secretary JISC, UK
Title:
Update
on United Kingdom Network Provision and International Connectivity
Abstract: The presentation will provide an update on UK network provision
and international connectivity.
The changing requirements of the academic user communities (eg research,
universities and colleges) will be discussed as will the need to develop
international collaboration in relevant generic middleware applications
such as authentication and authorization.
2: George McLaughlin
Director, International Developments, AARNet Canberra, AU
Title: Driving bandwidth-hungry applications:
SX-TransPORT
- the infrastructure to support e-science
Abstract: High capacity networks have changed the way that global scientific
collaborative research programs are undertaken. Unique high-end instruments
(astronomical telescopes, particle accelerators) costing hundreds of millions
of dollars and capable of generating terabytes of data each day, are now
able to be accessed from anywhere with a very high speed connection to
the facility (gigabits per second). Analysing and visualising these massive
datasets can now be carried out in a different part of the world from
where the data is collected. Correlating data in real time from telescopes
in different parts of the world is providing major new discoveries in
astronomy. Multimedia immersive environments, streaming several hundred
megabits per second, coupled with haptic technology (adding the concept
of touch to 3-d video and stereo audio) enable people at different part
of the globe to work with the same experience as if they were in the same
room.
The national and regional Research and Education (R&E) Networks form
a global mesh of high capacity circuits on which we are building the next
generation of advanced communications services, middleware and applications.
Several demonstrators will be held in the broadband playground showing
the future capabilities that will flow from this kind of infrastructure.
Southern Cross Cable Networks (SX) and AARNet (Australia's Academic and
Research Network) formed an alliance to facilitate participation by Australian
scientists in these new global collaborative initiatives by announcing
the Southern Cross Trans-Pacific Optical Research Testbed (SX TransPORT)
comprising dual 10Gbps circuits linking AARNet Australian 10Gbps network
to Hawaii and the 10Gbps R&E networks in North America, Europe and
the Asia Pacific.

Title: Summary
of GEANT2
Abstract: The GEANT network brought 10 Gbps networking to Europe in 2000.
We are now well advanced with the implementation of its successor network
GEANT2. Instead of building a yet faster network GEANT2 is moving away
from traditional IP networking to offering a hybrid design. The presentation
will look at the background behind the planning decisions for GEANT2,
will describe progress in terms of its implementation and look at some
of the issues we face.
4: David West

Title: European
Outreach projects
Abstract: There are European initiatives to develop research networking
with regions where it is less well developed today: Mediterranean (EUMEDCONNECT),
Latin America (ALICE) and Asia (TEIN2). The presentation will briefly
review the model developed to undertake these projects, and describe the
progress and plans
5: Akira Kato
WIDE
Title: GLIF:
Global collaboration efforts on lambda networking
Abstract: GLIF is an informal collaboration to connect lambda network
links provided by the members in order to provide international lambda
networking for demonstration and experiments. One of the notable efforts
based on GLIF was performed in Oct 2004, in which an OC-192 lightpath
was formed from Geneva in Switzerland to Japan. This talk will cover how
such a global collaboration was implemented as well as issues involved
to the experiments
6: Baoping Yan

Title: Recent developments at the Chinese Academy of Sciences
Abstract: The speaker will address such diverse projects as GLORIAD and
HK-light and well as initiatives in e-science.
7: Yoshio Tanaka

Title: PRAGMA:
Cyberinfrastructure, Applications, People
Abstract: The Pacific Rim Application and Grid Middleware Assembly (PRAGMA)
is an open, institution-based organization, founded in 2002, to establish
sustained collaborations and to advance the use of grid technologies in
applications among a community of investigators around the Pacific Rim.
PRAGMA accomplishes its mission by conducting joint projects, sharing
resources, integrating middleware, and exchanging and training researchers.
We give an overview of PRAGMA's activities, accomplishments, and structure.
Furthermore we suggest area of future growth via applications and collaborations
of interest to the Asia Pacific Advanced Networking participants. In particular,
we will emphasis the PRAGMA experiment of making the grid usable on a
routine basis, the lessons learned from the application developers, the
grid middleware developers, and the network systems. Furthermore, we emphasize
the role of applications in focusing development of our activities. Finally,
we stress the role of human interactions to make this possible.

Title :
e-VLBI with the High Speed International Research Networks
Abstract: Developments of the Very Long Baseline Interferometry (VLBI)
technology had been practically realized along with the improvements of
the data recording technology using magnetic tapes. In the conventional
VLBI
observations, radio signals from celestial radio sources are received
at two or more radio telescopes and are recorded to magnetic tapes.
The tapes are then shipped to a correlation site and processed to calculate
cross correlation functions between data taken at different radio telescopes.
In this observation scheme, the sensitivity and the timeliness to obtain
results from observations are limited by the maximum speed of data recording
on magnetic tapes and the slow delivery of the tapes from the observing
sites to the correlation site. To overcome these limitations, efforts
have been made to transfer the VLBI data from observing sites to the correlation
site electrically. The observed data are transferred either in real-time
if the connecting network is fast enough to transfer the observed data
rate, or in near real-time if any kinds of data buffering is required
at the observing site. In either case, the technique is called as e-VLBI
to distinguish it from the traditional tape-based VLBI.
Many radio telescopes around the glove are regularly participating in
the various VLBI sessions for research in geodesy, astrometry, and astronomy
by using the tape-based systems. If we can connect these observatories
with high-speed research networks and the e-VLBI observing systems, it
will dramatically improve the timeliness to obtain results from observations.
Especially, the value of UT1 can only be determined by geodetic VLBI observations
and the routine e-VLBI observation is desired by various research fields
which require accurate satellite orbits or rely on accurate terrestrial
and celestial reference frames. In addition, if the data transfer rate
becomes faster than the maximum recording speed on magnetic tapes, the
sensitivity of the VLBI observation will be dramatically enhanced and
it will expand the horizon of the radio astronomical observations. In
recent years, we have been performing various e-VLBI demonstration experiments
and routine sessions using the international high speed research networks
organized under the APAN. Initial results of these activities and future
plans will be reported in the presentation
9: Ted Hanss
University of Michigan Medical School
Title: Global
Medical Education Research Network
What if collaboration around medical education could occur without regard
for time or location? Complementing this morning's presentation focused
on hospital-based clinicians cooperating through videoconferencing, a
group of medical schools have been discussing plans to develop a Global
Medical Education Research Network. This is not a "virtual medical
school". Rather,
given the global issues surrounding human health, can we establish a collaboration
environment for both medical school faculty and students cooperating with
colleagues around the world? The infrastructure being discussed will support
everything from students working on team projects to formal seminars with
speakers and audience members participating from their
home sites.
The technology to produce this event exists and is in use on our campuses.However,
it will take work to package the technology together in a way that it
is not itself the focus of attention----such that the ease-of-use allows
the participants to focus on the content of the presentations. We are
currently distributing a scenario document, which will be reviewed in
the
presentation. This document is available at <http://www-personal.umich.edu/~ted/GMERN>.
In addition, technical staff have been establishing plans for trial uses
of technology to demonstrate the capabilities to faculty and students.
The intention of this presentation is to recruit a larger group of participants
in this emerging
effort.

Objectives: For several years ago, we can not have enough bandwidth networks but
recently the bandwidth grows quickly then we can not use its full
performance. During we suffered narrow band networks, we have
developed compression technologies , cache technologies etc but
sacrificed delay time. Now a day, if we make good use for high
broadband networks such as 10G, we must change the strategies, we may
not need compression or cache technologies longer. In this workshop,
we have presentations such the applications for the NGI. And these
broad-bandization will comes to every economics soon or eventually but
quickly. Then this topics is not interesting in by only economics who
already get NGI but also every economics.

Title: Reliable
File Transfer Method Using Data Size as a Sequence
Indicator Abstract: With block
transfers, a file is transferred in fixed chunks size made up of a header
portion (transmission sequence number and sometimes with a block length)
followed by a data portion, these sequence numbers are used by the sender and
the receiver sides to coordinate and to recover from loss or duplicate chunks
and sometime for reordering purpose as well. This paper proposes a reliable file
transfer method using data size as a sequence indicator, our proposed method
also allows for more efficient use of the available bandwidth, as we are able to
remove the sequence number portion that is currently used within most algorithms
like FTP. 2. Dr.

Abstract: The REN-ISAC (Research and Education Networking Information Sharing and Analysis
Center) is an integral part of the U.S. higher education strategy to improve
network security through information collection, analysis, dissemination, timely
warning, and response, specifically designed to support the unique environment
and needs of organizations connected to served higher education and research
networks. Supported by Indiana University and through relationship with EDUCAUSE
and Internet2, the REN-ISAC supports efforts to protect cyber infrastructure by
participating in the formal framework of U.S. ISACs. This presentation will
describe REN-ISAC activities, with an aim to explore opportunities for
cooperation with Asia-Pacific research and education networks.
2. Greg Wickham <Greg.Wickham@aarnet.edu.au> Keeping
Network Monitoring Current using Automated Nagios Configurations
Abstract:
A significant challenge managing a large and growing network is ensuring
that all network devices are appropriately monitored. If attempts are
not made to keep the monitoring current then it is possible that major
events on the network will go unnoticed.
To solve this problem a proof of concept was undertaken where the important
attributes of the network devices were stored in an XML file. This file
was then used as the key configuration repository for both validating
the status / configuration of the network and generating Nagios configuration

Measurement and Security
Abstract:
Network security is important, especially when the capability of Research
and Education networks reaches multi gigabit throughput. There are numerous
tools available to monitor activity and provide both an early warning
system to infections and monitor malicious activity on the network. With
the growth of malicious activity on the network it is important that we
cooperate to contain that activity.
4. John M Hicks <jhicks@iu.edu> & T.Ikeda Observatory:
Measurement Infrastructure
Abstract: Measurement data collected from critical points along the network path provides
valuable information for engineers and researcher to debug problems and
improve application performance. The Abilene Observatory is a successful
program from Internet2 that supports the collection and dissemination of
network data associated with the Abilene Network in the United States. This
talk will focus on the deploy of an Observatory like infrastructure in the
U.S and Japan to support Transpacific measurements across TOPS-TransPAC2 and
other links that connect APAN to U.S. and other network resources. This
work is supported by a collaborative effort between APAN-JP and the TOPS-TransPAC2 project from Indiana

Abstract:
One of the key component to construct a single-server Data Reservoir
for
10 Gbps internet is a high-speed TCP. We proposed "optimization of TCP
by inter-layer coodination", and did experiments to evaluate the
feasibility on actual Long Fat pipe Network at SC2004. We used about
31,248 Km 10 Gbps network from CERN to Pittsburgh, USA via Tokyo using
WIDE, APAN/JGN2, IEEAF/Tyco, CA *net4, Abilene and SURFnet. As a result
of the experiment, we measured 7.21 Gbps single-stream TCP data
transfer, which is recognised as Internet Land Speed Record by
Internet2.
In the presentation, we discuss on technical and non-technical issues
to
realize high-speed TCP experiment at SC2004.

Performance
Abstract: As international circuits are migrated to speeds of 10 Gigabits per second,
the distances and bandwidth available provide interesting challenges to
traditional layer4 stacks. This talk will survey some of the work being done
on TCP at various institutions throughout the world, with a focus on the
results obtained during the Supercomputing 2004 bandwidth challenge.
8. Osamu Tatebe <o.tatebe@aist.go.jp> Belle/Gfarm
Grid Experiment at SC04
Abstract:
This talk introduces the Gfarm Grid software, and describes Belle/Gfarm Grid
experiment at SC2004. In this experiment, we demonstrated (1) online
distributed data analysis, and (2) large-scale data analysis using four
sites; KEK, AIST, SDSC, and SC2004 conference hall in Japan and US. The
experiment (1) would store the online raw data generated by KEKB accelerator
to a Gfarm file system that is a shared file system consisting of AIST and
SDSC clusters. The stored raw data would be analyzed in parallel. The
snapshot of histogram would be displayed every 5 seconds at SC2004. The
experiment (2) would try to analyze terabyte-scale data in US using a cluster
in Japan. During this experiment, the large-scale data would
be transferred from US to Japan. We will report the performance of
data transfer using the JGN2 10Gbps international network.

Abstract:
Over the past six months AARNet (Australia's Academic and Research Network)
and ResearchChannel have collaborated on a number of projects to develop
and operate compressed and uncompressed High Definition video conferencing
using the SXTransport, Internet 2 and NLR networks.
The SuperComputing 2004 event provided a unique opportunity to operate an
uncompressed High Definition video conference between Canberra (Australia),
Seattle (USA) and Pittsburgh (USA) for the duration of the conference.
This presentation provides a status update on the current AARNet and ResearchChannel
collaborations and covers the steps required to construct the network, systems
and production elements required to run a demonstration with a 1.4Gb bidirectional
data flow.

High
Performance Remote File System
Abstract :
Using an HPC-server, we must manage huge data that is almost |impossible
to copy to remote computer over the Internet. For example, on our
organization research field: CFD, 273MB/s and 30GB/file are needed.
Even if copy operation is possible, we must manage multiple replicas to
keep data coherency. So we developed high performance remote file
system named SRFS: Shared Rapid File System on Ether. The file system
already enchmarked 56-90 Mbps on Fast-Ethernet and 600 Mbps on Gigabit-Ethernet
without TCP/IP tuning on Japanese domestic network. In this presentation,
I'll show the result of SC2004 BWC that used the Pacific Ocean link.
12. Katsushi Kouyama <kouyama@kyushu.jgn2.jp> The
LAC/UIC experiences through JGN2/APAN during SC04
Abstract:
UDT(UDP-based Data Transport Protocol) is an application level transport
protocol used in distributed data intensive applications.
This new protocol motivated by the emergence of wide area high-speed optical
network, in which TCP is often found to fail to utilize the
abundant bandwidth. UDT demonstrated good efficiency and fairness characteristics
in high performance computing applications where a small
number of bulk sources share theabundant bandwidth. It combines both rate
and window control and uses bandwidth estimation to determine the
control parameters automatically. In this presentation, we show the outline
of UDT protocol and the results of bandwidth challenge through JGN2/APAN
at SC 2004.
