Tuesday, 5/3   Location
8:45 AM - 10:00 AM MyVOCS - My Virtual Organization Collaboration Suite  [Session Evaluation]

   Jill Gemmill , Clemson University  [htm]  [ppt]
   Jason Lynn , University of Alabama at Birmingham
   John-Paul Robinson , University of Alabama at Birmingham  [htm]  [ppt]

Virtual communities form around a common interest and typically cross institutional boundaries. The task of establishing on-line collaboration tools, so essential to virtual organizations, can quickly become mired in the difficult problems of tool selection, identity management and access control. Collaborations are hampered when there is no single tool or site that can satisfy all requirements and the quality of collaboration suffers.

Most solutions assume a central administration body will provide and manage the service; we will demonstrate a 'Just In Time' approach for creating virtual organizations that provides an easy way for anyone to create, manage and share their own collaboration space, without requesting special permission or requiring a portal.

Virtual organizations define and assign members' roles in the VO and are the authoritative source for these attributes. MyVOCS/MyVO provides an attribute aggregator service that is the VO's attribute authority for Shibboleth. This approach combines institutional identity management and VO specific attribute authorities and leverages Shibboleth to distribute member attributes to all collaboration tools, across institutional and administrative boundaries. VO attribute federations provide a consistent user experience to researchers based on their role in the virtual organization. MyVO is a virtual organization provider infrastructure that enables members of an identity federation to dynamically create virtual organizations. VO members establish collaboration specific attributes which are distributed via Shibboleth to all collaboration tools. This presentation reports on work done by NSF ANI-0330543 NMI Enabled Open Source Collaboration Tools for Virtual Organizations.

   Jill Gemmill , Clemson University  [htm]  [ppt]
   Jim Phelps , University of Wisconsin-Madison
   Paul Russell , University of Notre Dame

This session involves discussions related to middleware-enabling the mailing list application, focusing on the work of the MACE-MLIST Working Group since the last I2 member meeting. First, results from our survey of campus mailing list administrators will be presented; about half the respondents indicated that they are considering changing their current choice of mailing list software. Find out what functionality is most important to mailing list administrators and strengths and weaknesses of commonly used packages. Second, we will present a high-level review of candidate middleware integration points in the mailing list application. Last, Serge will lead a discussion about which new technologies may be useful for controlling spam into and out of mailing lists. Mailing list servers may be wrongly placed on ISP blacklists; what information might be required to prove that your mailing List server is not a spam machine? What technologies on the horizon may provide solutions for authentication of the mailing List service? MACE-MLIST, working with the open source Sympa development team, is interested in developing a reference document describing solutions to these problem; this discussion will serve as a kick-off towards that effort.

3:00 PM - 4:00 PM Leveraging Middleware for Unified Campus Services - Case Studies: H.350 Directory Services for Multimedia Conferencing  [Session Evaluation]

   Larry Amiot , Argonne National Laboratory  [htm]  [ppt]
   Jill Gemmill , Clemson University  [htm]  [ppt]
   Jason Lynn , University of Alabama at Birmingham  [htm]  [ppt]  [htm]  [ppt]
   Frank Reinemer , Danet Consult  [htm]  [ppt]  [htm]  [ppt]
   Kewin Stoeckigt , AARNet  [htm]  [ppt]

A panel of people from very different environments who have each implemented H.350 at their respective institutions will present why they selected H.350, architectural decisions made during their deployment implementation, and what new advantages exist as a result of their deployments.

Jason Lynn's implement ion at a large research university includes both room and person listings and is integrated with the campus directory. Frank Reinemer was hired by a very large German corporation for an internal videoconferencing management solution. Kewin Stoeckigt has implemented H.350 for the German national research network and uses H.350 to solve the fire wall traversal problem . Larry Amiot has recently implemented H.350 for a SIP deployment. A basic familiarity with the H.350 LDAP schema is assumed.

Conventional TCP can serve advanced applications poorly because of both limitations of its congestion control algorithms (increased delays and sensitivity to even minor non-congestive packet loss) and limitations of its application programmer interface (sequential nature of data delivery to the application); in addition, TCP window size (and the corresponding send and receive buffers) is often left by system administrators at its default setting, which is too low for high-performance networks. In this session, advanced application requirements for transport protocols and ways to satisfy these requirements will be discussed.

   Erik Hofer , University of Michigan  [htm]  [ppt]

Recent expert reports and research funding trends suggest that research groups will increasingly operate across geographic boundaries, forcing organizations to adapt to the problems of distributed collaboration. At the University of Michigan, personnel at the School of Information are split nearly evenly between two buildings that are nearly three miles apart, making the virtual organization of tomorrow a reality today for faculty, staff and students.

This talk will provide an introduction to one effort to minimize the impact of this dispersion, the Connection Project. The Connection Project is an experiment in the development, deployment and evaluation of high-quality conferencing technologies within the School of Information using the University's shared network infrastructure. The project leverages a number of high-bandwidth technologies, such as DVTS and high-resolution MPEG-4 capture, to provide an extremely high quality conferencing experience between the two locations.

This presentation will focus on the design and deployment of the facilities and will present findings from studies of the human factors and organizational impacts of the Connection Project systems that will be instructive to other projects trying to leverage high performance networks, such as Abilene, to overcome the barriers of distance in their work.

   Jan Eveleth , Pacific Northwest GigaPoP  [htm]  [ppt]
   Katsuyuki Hasebe , NICT
   Akira Kato , WIDE

At 8:30pm Pacific time on January 17, 2005, Prof. Larry Smarr of the University of California San Diego began his keynote address from Seattle, Washington to hundreds of dignitaries attending the JGNII symposium held in Osaka, Japan where the local time was 1:30pm on January 18, 2005. In this produced event, Prof. Smarr used technology and media (ResearchChannel 1.5Gbps uncompressed high-definition video conferencing over IEEAF/PNWGP/WIDE/JGNII 10Gbps trans-Pacific links) that was the subject of his presentation, "Using OptIPuter Innovations to Enable LambdaGrid Applications." Application, networking, and administrative staff from several international networking and research groups cooperatively designed, planned, and executed this significant event.

This presentation will discuss all behind-the-scenes facets of this production (technical, operational, management) and will highlight the critical role of integration and communications across each of these functional areas. We will discuss the production process, what worked, what didn't work and give our predictions on the evolution and future of what we believe will be many, many more joint efforts such as this.

WebLabs for Advanced Internet
The Weblabs applications allow the access and usage of the experimental real laboratories by remote virtual laboratories. These kind of applications can be provided due to the use of the Advanced Internet that ensures high quality connections in terms of data transmission rate, low delay and reliability between the interconnected virtual and real laboratories. In this presentation, some examples of WebLabs in the areas of chemistry, physics, biology (bees colony control and monitoring) and medicine (usage of a remote 2D image repository for equipment tuning), which are under development for Advanced Internet in Sao Paulo - Brazil, will be described. The goals, the basic architecture and the expected results of these WebLabs will be discussed, showing how researchers and students can benefit from this type of applications.

Real Issues and Scientists' Tools Bring Science to Life in the Classroom
Real-time, remote access from the XL-30 Environmental Scanning Electron Microscope to the K-12 classroom is one of the newest and most exciting educational tools now available from the Nanocharacterization Lab housed within the Center for Advanced Materials and Nanotechnology at Lehigh University. Educational Technology Specialist George Motter of Lehigh University's Library and Technology Services and Andrea Harmer, Director of Web-based Materials Science Education, will present on how this new tool is allowing students to actively explore their own specimen's physical and chemical attributes down to the near-nano scale.

Experiences Delivering Massive Geospatial Datasets for Educational Use
Orthophotographs are aerial images, taken from either an airplane or satellite, transformed to account for camera location, orientation and ground elevation to produce a uniform scale image. Due to this transformation, they are routinely used as base images in GIS systems. Seamless orthophoto datasets exist and would be of great educational benefit to many university departments. For example, imagine forestry, agriculture, or city planning students zooming and panning across the United States to view any national forest, farmland, or city instantaneously from the classroom. Presently, we have access to a 22TB, 1-meter resolution, black and white orthophoto dataset of the United States, generously made available (for evaluation purposes only) by AirphotoUSA. In order to evaluate the educational impact of this material, we conducted a pilot study involving several Internet2-connected university classrooms. We measured server and network loads generated by labs of students accessing the data to complete an instructor-assigned lab activity. We also conducted student and instructor surveys to determine the impact of using orthophoto data as a pedagogical tool. Using the results of this study, we hope to develop best practices for data delivery and use these practices, as well as the allure of the dataset, to encourage educator collaboration via a virtual team.

   Mark Cotteleer , Marquette University  [htm]  [ppt]
   Dick Nolan , University of Washington/Harvard Business School  [htm]  [ppt]

This session describes an initiative that has been underway for about two years as a partnership involving Internet2, Harvard Business School, and several other universities and technology companies. The purpose of the "Business Applications Group" is to accelerate the adoption of advanced networking applications in business. Inspiration for this effort arises from the observation by certain Internet pioneers that the elapsed time between the creation of the Internet (late 1968) and widespread adoption in business (late 1990s) seems unreasonably long. We aspire to shorten that cycle for the next generation Internet.

   Kurt Buehler , ImageMatters LLC
   Karen Frederickson , The Polis Center, IUPUI
   Marlon Pierce , Indiana University
   Mark Reichardt , Open Geospatial Consortium

Many recent events have highlighted our vulnerability to both natural and anthropogenic disasters. The impacts of floods, tornados, wildfires, agricultural blights, terrorist acts, and other events are felt in terms of human suffering, property damage, loss of livelihood, economic deterioration, and environmental destruction. Efforts to reduce the impacts of emergencies and disasters require getting the right information to the right people at the right time. The current "non-system" does not effectively use the wealth of information that resides with various organizations.

Our ability to collect high quality, high resolution data has undergone a revolution, but information management has not kept up. The nation needs a more effective information infrastructure to support its emergency preparedness and response communities. We are proposing to address the critical information technology requirements of disaster and emergency response communities by creating CrisisGrid, a data and systems infrastructure built upon a Grid of Grids approach to advance the ways in which information is monitored, analyzed, modeled, visualized, and delivered. Through a partnership among IUPUI, IUB, Purdue, and the Open GIS Consortium, we propose to apply Internet, Grid, GIS, sensor, and visualization technology to the emergency preparedness and response (EPR) and critical infrastructure projection (CIP) activities of government and business.

Our presentation will discuss our initial model of this new approach to critical information technology, which focuses on an area of disaster management of concern to Indiana's floods.
