Types of application Example applications List of projects by discipline References 1 1. Internet2 Internet2 is a not-for-profit consortium, led by over 200 US universities, developing and deploying advanced network applications and technology, accelerating the creation of tomorrow's Internet. 2 Internet2’s Mission Facilitate and coordinate the development, deployment, operation, and technology transfer of advanced, network-based applications and network services to further US leadership in research and higher education and accelerate the availability of new services and applications on the Internet. 3 4 Abilene • Internet2 backbone network (IP over SONET) • A project of the University Corporation for Advanced Internet Development (UCAID) in collaboration with various corporate partners 5 Link Capacities • 13,000 miles of fiber optic cable, with over 8,000 miles of interior circuits and another 5,000 miles of access circuits • Operates at OC-192 (9.6 gigabits per second) or about 354,000 times faster than a typical computer modem. 6 7 Abilene Weather Map 8 9 2. Types of Applications Internet2 applications require enhanced networking functionality—such as high bandwidth, low latency (delay) and jitter, and multicast—not available on our commercial Internet connections. 10 Attributes in the Most Compelling Applications 1. Interactive collaboration environments, where users can truly interact with others without the barriers of distance. 2. Common access to remote resources, such as telescopes and microscopes. 11 Attributes (cont.) 3. Using the network as a "backplane" to build network-wide computation and data services (Grid computing). 4. Displaying information through virtual reality environments—moving from static graphics and images to moving, threedimensional animations. 12 3. Example applications • Grid computing • Telemedicine • Astronomy • Tele-immersion • Music • Digital Video • Tele-Operation of Remote Equipment 13 The Grid project • Using the network as a "backplane" to build network-wide computation and data services. • It enables scientific exploration, which requires intensive computation and analysis of shared large-scale databases, from hundreds of TeraBytes to PetaBytes, across widely distributed scientific communities. 14 The two biggest centers For Particle Physics Fermilab near Chicago CERN in Geneva 15 The Computing Challenge 3.5 PetaBytes / year ~108 events/year 16 Telemedicine • During a surgery performed at Ohio State University, Abilene was used to conference with doctors from other parts of the country. • An MRI machine can scan a patient in one location and send the data to a remote supercomputer for processing, and then deliver the resulting images to a doctor in a third location. 17 Telemedicine (cont.) A specialist in Boston could give advice to a doctor in rural areas for on-site medical care, or even guide that doctor during a surgery. A medical student could watch a rare procedure that would otherwise be unavailable. http://www.cnn.com/2000/HEALTH/10/02/inet2.de mo.story/index.html 18 Telemedicine (cont.) • Anatomical and Surgery Simulation over the Internet • The "trainee" could feel the actions and force of the instructor's "hand". 19 Radio Astronomy • Electronic transmission of Very Long Baseline Interferometry (e-VLBI) data from the Haystack's Westford Observatory and NASA's Goddard Geophysical and Astronomical Observatory, which were streamed over Internet2's Abilene Network to the Haystack correlator at 512 Mbps. • The live results were displayed in a 3D plot (correlation amplitude, differential Doppler, differential delay) in Pittsburgh as the data were correlated. 20 21 Tele-immersion • Tele-immersion creates coordinated, partially simulated environments at geographically distributed sites so that users can collaborate as if they were in the same physical room. 22 National Tele-immersion Initiative NTII 23 Tele-immersion (cont.) In the case of medical applications, such as tele-radiology and urgent diagnostics, the availability of such technologies in the places that are physically inaccessible to specialists could potentially save the lives. Off-shore ships and oil rigs are good examples of such environments. 24 Demo The participants in this session were not only able to see each other in 3D but they were also able to engage in collaborative work, and take part in a design process (a simple example of interior office design) 25 Music •College music professors can now be in several places at once delivering highquality audio and video via high-speed connections. An excerpt of MTT conducting from Miami, an orchestra in Cleveland, on October 29th, 2002 New World Symphony An excerpt from CNN's 'Science and Technology Week' spotlighting a NWS Internet2 demonstration between Miami and Atlanta 26 Real-Time Tele-Operation of Remote Equipment North Carolina State • Tele-vator is a computerized excavation backhoe that can be remotely operated over Internet2. • Because of its size and potential criticality of operations (e.g., in rescue hazardous situations) Tele-vator requires a high level of sophisticated two-way feedback, including adequate depth of vision provided via highdefinition stereovision. • Guaranteed Quality-of-Service (QoS) — such as network bandwith, latency control, and jitter control — are essential to insure the quality of the 3D image, audio, and equipment control channels. 27 nanoManipulator: Seeing and Touching Molecules (6 min) Scanning-probe microscopes (SPMs) allow the investigation and manipulation of surfaces down to the atomic scale. The nano Manipulator (nM) system provides an improved, natural interface to SPMs, including Scanning Tunneling Microscopes and Atomic Force Microscopes. The nM couples the microscope to a virtual-reality interface that gives the scientist virtual telepresence on the surface, scaled by a factor of about a million to one. 28 4.
