www.datatag.org StarLight, TransLight, OMINet: CERN-iCAIR Advanced Optical Networking Demonstrations at WSIS 2003 For WSIS 2003, CERN and the International Center for Advanced Internet Research (iCAIR) designed several demonstrations of next generation high performance networking, based on next-generation, intelligent optical networking technology and dynamic data services provisioning. These demonstrations indicate the potential for creating new global applications as traditional barriers to network optimization at multiple levels are removed. The demonstrations are based on high performance communications infrastructure utilizing novel techniques and technologies for managing globally distributed resources and extremely large volume data streams. The innovative networking methods being developed by these organizations and their research partners allow for very high performance global applications - especially those based on Grid technology - across multiple disciplines and industries. The demonstrations also utilize initial components of the “Global Lambda Grid,” a concept that is being formulated by the StarLight community, which envisions supporting Grid-based applications through world-wide wavelength-based data communications. StarLight, which is a component of this concept, is a next-generation international optical networking exchange facility in Chicago. An initial implementation of this capability is being provided through TransLight, a global advanced optical network. Many of the advanced technologies supporting the demonstrations were developed on, or for, OMNInet, a metro area photonic networking testbed in Chicago. OMNInet has been established, in part, to create a reference model for next generation optical metro networks. For WSIS 2003, this testbed has been extended to Geneva through the CERN/DataTAG presence at the StarLight and the 10 Gbps DataTAG transatlantic link to CERN in Geneva. The demonstrations show that photonic enabled data communications are possible not only on next generation optical metro area networks, such as OMNInet, but can also be extended to global networks, e.g., through StarLight and CERN’s networks, as a basis for the Global Lambda Grid. The demonstrations indicate the potential for advanced data communications based on dynamic multiwavelength lightpath provisioning and supported by flexible dynamic DWDM-based networking technology – as opposed to today’s static point-to-point optical networks. The demonstrations also show capabilities for applications to directly discover and signal for the networking resources that they require, including signaling for the provisioning of lightpaths.

One example is given here, medical training. In December 2003, Northwestern University Department of Radiology, iCAIR, Prous Science, and Video Furnace will be supporting a unique event in medical imaging at the world’s largest medical conference held in Chicago, sponsored by the Radiological Society of North America (RSNA) and attended by 60,000 participants. For the first time ever, a live plenary session will be multicast internationally from McCormick Place in Chicago, using 1 MPEG2 2 Gbps for the image and one for the event. This popular session guides attendees on how to identify abnormal findings on imaging studies, how to construct a list of differential diagnoses based on the imaging findings, and how to make recommendations for further procedures or treatment, if necessary. The Radiological Society of North America is accredited by the Accreditation Council for Continuing Medical Education (ACCME) to provide continuing medical education for physicians. In the future, advanced optical networks will as described in this paper will allow for much higher resolution medical images (100s of times the resolution of current images) produced such conferences to be multicast wolrd-wide.
