Corporations in PA, NJ, and DE have research and educational opportunities to participate in high performance networking with MAGPI and Internet2 subscribers as an extension of their business goals and objectives.

Advanced Video Technologies

Advanced video technologies and collaborative tools are allowing organizations on the MAGPI and Internet2 networks to communicate in new and exciting ways.

Access Grid® is a suite of collaboration technologies that enable large scale (wall or room sized) group collaboration including live video, audio, and data sharing. The Access Grid® is an ensemble of resources including multimedia large-format displays, presentation and interactive environments, and interfaces to Grid middleware and to visualization environments. These resources are used to support group-to-group interactions across the Grid.

Microsoft Research's Conference XP software allows for distributed interactive collaboration spaces using a virtual venue. It integrates recent advances in high-performance audio, video, and network technologies to seamlessly connect multiple, distant participants in a rich, immersive environment for distance conferencing, instruction, and collaboration. ConferenceXP provides an extensible foundation for interactive collaborative environments and serves as a research platform for designing and implementing distance conferencing and learning applications. Currently, it is being used for multi-institutional instruction, distance learning, and advanced research collaboration. MAGPI runs a Conference XP test node that is available to MAGPI Members.

The Digital Video Transport System (DVTS) is a simple and inexpensive method of transmitting high-quality video and audio over the Internet. DVTS uses 30 Mbps uncompressed video to provide high-quality images with low latency. DVTS can also be used in multicast mode to allow three or more sites to participate in a single conference. More broadly, DVTS is a step toward a world in which you will be able to tune your computer to a series of educational channels the same way you tune your television to satellite channels—send and receive high-quality video across the Internet with the same ease as sending and receiving email - - and do all this without any significant capital expenditure.  DVTS-based telemicroscopy is used for real time clinical case consultation between pathologists at the three Philadelphia hospitals that make up the University of Pennsylvania Health System. The Office of Cultural Affairs at Montgomery County Community College used DVTS to conduct dance critiques between dancers in Pennsylvania and choreographers in Japan.

Dynamic Circuit Networks

A new service offering from Internet2 called “Dynamic Circuit Networks” gives MAGPI the ability to provide from 1Gbps to 10 Gbps of bandwidth from an appropriately connected institution in PA, NJ, or DE to another similarly connected site in the United States and even specific locations in Europe.  Campuses of universities and research facilities can dynamically create these pathways for limited periods of time and then disconnect the circuit when the application is finished.  This resolves issues such as the research requirement for large amounts of bandwidth, but limits the financial responsibility to the length of the transmission.  Once the internal infrastructure is created, institutions can share this high capacity access for minimal cost and effort.  The University of Pennsylvania has requested this service for downloading very large files to their High Energy Physics Department from the Large Hadron Collider [PDF] in Cern, Switzerland.

Interactive Videoconferencing

Videoconferencing allows people in geographically distributed locations to see and hear each other and collaborate in real-time. Increasingly, videoconferencing is becoming part of the standard set of tools used by teachers, students, faculty, staff, librarians and researchers to enhance communication, training, and instruction. Public and cultural organizations are using videoconferencing to expand their outreach opportunities and reach audiences beyond their geographic proximity through virtual lectures and field trips. MAGPI supports the use of videoconferencing within our member community through interactive educational programming, training and technical support.

MAGPI Members can facilitate multisite videconferences through MAGPI’s Internet2 Commons subscription. This service provides a large-scale deployment of tools for one-to-one, one-to-group, and group-to-group collaborations enabling the Internet2 research and education community to hold distributed working groups, classes, meetings, and events. As of July 1, 2009, this MCU service available to our members for $15/connecting site/ hour for your events. Through this service offering, MAGPI members can conduct multi-site videoconference events, as well as webstream those events live and archive them.

Multicast

Multicast is a set of technologies that enables efficient delivery of data to many locations on a network. In today’s Internet, the dominant model of communication is “unicast”—the data source must create a separate copy of the data for each recipient. When there are many recipients, and when large amounts of data (e.g. streaming video) are being sent, unicast becomes prohibitively wasteful of bandwidth. The key idea behind multicast is to create each recipient's copy of each message at a point as close to that recipient as possible, thus minimizing the bandwidth consumed. In July 2007, MAGPI worked with the Friends of Live Earth Global Screens Program to send out a 30 mbps webstream of the 24-hour Live Earth Concert to campuses and organizations on the MAGPI and Internet2 networks, as well as other research and education networks worldwide. Northwestern University and Video Furnace, in collaboration with C-SPAN and Internet2, make live, high-quality C-SPAN and C-SPAN2 broadcasts [PDF] available 24 hours a day to anyone with an Internet2 network connection that is multicast capable.

The Internet2 Commons

Supported by and developed with its members, the Internet2 Commons has deployed an H.323 Videoconferencing Service for multi-site connections. Standards-based, vendor-neutral videoconferencing through this scalable service allows subscribing members to schedule and hold distributed working groups, classes, meetings, and conferences in support of research and education.

The Internet2 Commons encourages the large-scale deployment of tools for one-to-one, one-to-group, and group-to-group collaborations. The services provided by The Internet2 Commons are available to Internet2 members, Internet2 Network participants, and other Internet2 partners. The Internet2 Commons provides multi-party videoconferencing services with advanced features such as simultaneous streaming, archiving, high-bandwidth support, and multiple video layout options. Internet2 members and partners can connect to their peers, independent of endpoint brands, through an existing Internet2 network connection.
