Internet Search in Multimedia Data


  • Ivan Dolezal
  • Michal Krsek

As the broadband access to the Internet is becoming more frequently used, audio and video content is getting more popular. But there is no solution for Internet searching in these types of data. There are three ways to search this material: search directly in the material, search on referring web pages and search in metadata. We developed methods how to index metadata included in the material and implemented them into full text search engine searching the Czech Internet. Description of this project, technical details and results are subject of this poster.

Network deployments will be highlighted with an illustration featuring newly introduced technology supporting R&E networks. Capabilities such as and selective OADM technology, and automated provisioning and management will be illustrated within context of R&E network deployments.

The inSORS Access Grid Solution: Commercial Uses/Research Collaborations
ChevronTexaco Corporation Intelligent Optical Networks in Research & Education

inSORS Integrated Communications, Inc.

  • John Harrison

inSORS’ development and integration efforts around the original Access Grid prototype have resulted in a stable, commercial class inSORS Access Grid platform that several large companies are currently deploying. The Access Grid is a popular collaboration platform running on the Internet2 network. ChevronTexaco North America was looking to increase communications between remote sites. The inSORS solution proposed to enable high performance demonstrations to business users within the context of a high value added decision-making process. Within the scope of this project, the inSORS AG would deliver an acceleration of that business process through the inclusion of remote experts. inSORS also took ChevronTexaco through the process attributes that are in the Access Grid's "Sweet Spot" based on other large customer experiences. ChevronTexaco now has eight complete room based inSORS AG nodes along with several single node or laptop deployments. (Located in their San Ramon, Richmond, CA, Houston, Lafayette, New Orleans and Lagos, Nigeria offices) ChevronTexaco has also used their internal AG nodes to collaborate with several University based researchers. Their custom Virtual Venue enables private, secure communications within their corporate firewall. The venue also allows for lower bandwidth sites to connect, as well those that are not multicast enabled. As with most of our commercial customers, ChevronTexaco has limited multicast availability and some sites are still at T-1 bandwidth levels so this feature was a big plus in their decision to go with the inSORS solution. In the initial three-month trial period, the inSORS AG was used for a total of 110 multipoint team project meetings. Further rollout will include offshore rigs, international sites, suppliers, and partners.

Comparing Two Translation Techniques of IPv6: NAT-PT and ALG

UFRGS - Federal University of Rio Grande do Sul & Comitê Gestor - Internet BR

  • Andrey Vedana, UFRGS - Federal University of Rio Grande do Sul

We report the results of a performance comparison between Network Address Translation with Protocol Translation (NAT-PT) and Application Layer Gateway (ALG). Different scenarios are provided as well as different types of operational systems and network situations, including free and congested network segments and routers, using Cisco and software-based routers, and the situation where each one must be used and why. The performance tests were made using daily work traffic and under pressure traffic, to generate stress. Same of the results are in tables, crossing the performance between routers/applications/operational systems, as well as in charts explaining the best combinations found in different situations. This work was developed in two Brazilians states: Rio Grande do Sul and São Paulo, in distinct networks.

Next-Generation 10 Gb/s WDM Systems

Meriton Networks

  • Brian Pratt

Ten Gb/s WDM Systems have been around for a while, initially designed for long-haul and ultra-long-haul, point-to-point, optical networking applications. With the introduction of 10 Gigabit Ethernet, 10 Gigabit Fibre Channel, and other 10 Gigabit services in metro network and regional applications, next-generation WDM systems have emerged. This presentation will examine the benefits in the areas of cost, flexibility and efficiency, and provides practical advice to those looking to deploy next generation 10 Gigabit WDM systems.

Telescience Applications for Internet2 IPv6 Networks: Systems for Remote Control and Monitoring of High Throughput Instrumentation

National Center for Microscopy and Imaging Research (NCMIR)

  • David Lee

The Telescience Project gives remote access to steerable, high-energy electron microscopes and the necessary computation and data storage environment to construct structures at the meso-scale (5-10 cubic nanometers to 100 cubic microns). The Telescience Project merges technologies for remote control, Grid computing, and federated digital libraries of multiscale, cell-structure data. Primarily joined by the Internet2 network, these technologies merge to provide a complete teleinstrumentation solution that will connect scientists’ desktops to remote instruments, distributed databases, high-performance analysis environments, and experiment planning. The Telescience system is designed to increase the throughput of data acquisition and processing and to ultimately improve the accuracy of the final data product. High-performance networks, such as Internet2, enable technologies for streaming high-definition video and connecting online computational and visualization resources for scientific discovery. High-speed networks are changing science by enabling researchers to remotely use one-of-a-kind instrumentation for data acquisition and instrument steering. These technologies are not possible with lower bandwidth networks, particularly due to the low latency and high bandwidth requirements of real-time applications such as high-resolution video and online computation or visualization for use in monitoring, collaborative experimentation, and intelligent steering of instrumentation.

Biomedical Informatics Research Network: Building a National Collaboratory for Brain Research

  • BIRN Coordinating Center at the University of California, San Diego (www.nbirn.net )

The Biomedical Informatics Research Network (BIRN) is an initiative within NIH that fosters large-scale collaborations in biomedical science that currently involves 15 universities (22 research groups) participating in brain-imaging projects of human neuropsychiatric disease and associated animal models. The BIRN Coordinating Center is orchestrating the development and deployment of key infrastructure components for support of the scientific goals pursued by these scientists: high-bandwidth, inter-institutional connectivity via Internet2, a uniformly consistent security model, grid-based file management and computational services, software and techniques to federate data and databases, data caching and replication techniques to improve performance and resiliency, and shared visualization and analysis environments. As a core component of this infrastructure, Internet2 provides the stable high-performance network required by these researchers to share and analyze data sets that continue to increase in size as imaging technologies advance. Researchers within BIRN also benefit directly from connectivity to high- performance computing resources, such as TeraGrid. For example, advanced analyses of anatomical structure used to gain a better understanding of diseases and disorders can produce multiple terabytes of derived data that must then be shared within this national collaboratory. Finally, Internet2 provides a solid foundation for the future expansion of the BIRN.

Presence, Integrated Communications and Location Based Services

PIC Working Group

  • PIC Working Group Members

Some of the IP-based communications applications that are likely to begin appearing on campuses in the next decade include Rich Presence, Integrated Communications, and Location Based Services. Rich Presence seems poised to develop into a sophisticated set of tools to publish a user's communications state and preferences.  Early forms of Integrated Communications can be seen in today's Columbia University's SIPc, Xten's Eyebeam, Wave3Software's Session and Microsoft's Windows Messenger, among several others.  Location Based Services leverages a wireless network's knowledge of user location to provide geographically appropriate services.  Group members will discuss the architecture used in trials to date and provide informal demonstrations.
