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.

Network Performance Measurement and Monitoring:  creating a global fabric across APAN, the US and Europe to support high-performance global network collaboration


Time: 2005.1.27 (thur)
16:00-17:30
Place: Room B 

Organizing Chair:
Heather Boyles, Internet2 

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. Recent achievements by these groups and the latest piPEs-related project developments will be presented with an eye towards implementation and local benefits.

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.

DANTE
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: 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

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.

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.

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 data.
The presentation will provide an overview of the architecture that has been developed and highlight with comparisons to the process of managing Nagios configurations manually.

3.  Bruce Morgan <Bruce.Morgan@aarnet.edu.au>   Backbone 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:
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.

7.   John Hicks  <jhicks@iu.edu>    FTP 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.

11. Naoyuki Fujita <fujita@chofu.jaxa.jp>       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.

13. Jin Tanaka <tanaka@kddnet.ad.jp> & Chris Robb        Lessons Learned from SC2004 Bandwidth Challenge
Abstract:
