News / October 9, 2009<NICT Otemachi>

	NICT to participate as an exhibitor at Super Computing 2009 (SC09)
	-- First Look at the Research and Development Experiences at the NICT booth at SuperComputing2009 --

At the SuperComputing2009(SC09, November 14-20, 2009 Portland,USA), exhibitors aim to gain maximize data computing not only by a single computer’s processing speed, but by connecting distributed computers around the world by an high-speed network. At the exhibit, exhibitors will show their data processing’s diversity and speed by various experiments, presentations and demonstrations. SC09 is one of the world’s largest events to merge high-speed networks and high-speed computing, to be one of the most famous events in the field.
NICT’s exhibit at SC09 will show research and development progresses by NICT and its partners worldwide on the research area of high speed data transfer and processing. We will show by demonstrations, space weather forecast visualization, material analysis of famous artwork by Terahertz, and environment analysis and measurement by weather sensors, which all use huge amounts of data. This also will use the new generation testbed network, JGN2plus to connect to research and development partners worldwide. Also using the network, we will work with GLIF, Internet2 and others to interconnect various dynamic path creation protocols, such as G-Lambda and DCN. Also, we will be showing demonstrations done by a joint research will NTT. They showcase research in an application-network collaborative bandwidth on-demand network service with autonomic network optimization by IP-optical network virtualization and a high-accurate/precise 10-Gigabit network monitoring platform called PRESTA 10G.

<< Space Weather Forecast (NICT) >> Variations of space environment cause a number of serious hazards such as satellite failure, radio communication interruption, and radiation exposure to astronauts. Space Environment Group conducts research on space weather forecast to prevent these types of hazards by monitoring, modeling, computer simulation, and informatics technology. At the SC09, we will be showing the space weather forecast by various visualization methods, such as large-scale displays and rotating LED display.

<< Artwork Analysis by TeraHertz WaveLengths (NICT) >> TeraHertz wavelength (THz) is a very much looked after technology of non-destructive analysis. NICT has been working on using THz to do analysis of artwork which enables us to observe structure and materials which cannot be seen easily by either x-ray or infra-red waves. At the SC09, we will show a demonstration of analysis of Giotto's Polyptic of Badia, including our THz imaging results, using a Tiled Display Wall system.

<< Automatic Network Optimization with Application-Network Collaborative On-Demand Bandwidth (Joint Funded Research with NTT) >> NTT showcases research in an application-network collaborative bandwidth on-demand network service with autonomic network optimization by IP-optical network virtualization and a high-accurate/precise 10-Gigabit network monitoring platform called PRESTA 10G. Application of transmitting uncompressed HDTV stream collaborates with the optical network control in order to set up guaranteed optical circuits on demand. They also share information such as change of latency so that the application can adaptively change the configuration. Novel technology of IP-optical network virtualization enables not only the dynamic construction of virtual IP networks, but also reconfiguration of the topology in accordance to the changes of the traffic pattern. Also, we will use a network monitoring system called PRESTA10G, which can measure 10-Gbps network characteristics (jitters, delays, and traffic burstiness) focusing particularly on the stream traffic quality. By taking advantage of hardware-assisted monitoring extentions provided by the PRESTA 10G platform, it visualizes global multisite traffic characteristics in real time to see the influence of the traffic quality to the video quality. The measurement results are given at micro-second resolutions, finer than existing measurement methods such as SNMP monitoring.

<< Inter-domain Automatic Network Path Building (Joint Funded Research by KDDI Lab and Advanced Industrial Science and Technology) >>
This is an experiment which will be done first in the industry to connect a worldwide cloud networking entities seamlessly. This is made possible by connecting PC clusters used by the space weather forecast application with the world’s various dynamic networks (G-lambda, JGN2plus DCN, Internet2 ION, EU Harmony) using GLIF’s middleware.

<< A large scale sensor network for sensing environments of the earth (NAIST, NICT)>>
We demonstrate a large sensor network related with 'Live E! project'. This project consists of industrial/governmental/academia organizations including NAIST (Nara Institute of Science and Technology) and NICT (National Institute of Information and Communication Technology). Live E! project has installed weather sensors around Asian countries, Japan, Thai, Taiwan and others and share these sensor data through the Internet. Many organizations use these data for various purposes, such as prevention of floods, evacuation systems, educational materials, saving energy and etc. We introduce these activities of Live E! and its distributed data management system and show visualizations of sensor data. We also exhibit our sensors and show the weather information of SC09.

<< Acceleration of Long Distance Data Sharing System (University of Tokyo, NICT)>>
The Data Reservoir (DR) is a project led by University of Tokyo, NICT and others, composed of commercial companies / government / educational institutes. As part of this project, we will construct a international network system using international networks and interconnection points worldwide such as JGN2plus / SINET3 / StarLight / National Lambda Rail / Pacific Northwest GigaPop / Pacific Wave / IEEAF / T-LEX / WIDE. On this network system, we will realize a high-speed data transfer to the limit level on a worldwide network system using technologies such as inter-layer collaborative optimization and multiple stream optimization.
