- 2. Abstract Twenty years after the NSFnet launched today's shared Internet, a new generation of optical networks dedicated to single investigators are arising, with the ability to deliver up to 100-fold increase in bandwidth to the end user. The OptIPuter (www.optiputer.net) is one of the largest NSF-funded computer science research projects prototyping this new Cyberinfrastructure. Essentially, the OptIPuter is a “virtual metacomputer" in which the individual “processors” are widely distributed Linux clusters; the “backplane” is provided by Internet Protocol (IP) delivered over multiple dedicated lightpaths or "lambdas" (each 1-10 Gbps); and, the “mass storage systems” are large distributed scientific data repositories, fed by scientific instruments as OptIPuter peripheral devices, operated in near real-time. Furthermore, collaboration will be a defining OptIPuter characteristic; goals include implementing a next-generation Access Grid enabled with multiple HDTV and Super HD streams with photo realism. The OptIPuter extends the Grid program by making the underlying physical network elements discoveable and reservable, as well as the traditional computing and storage assets. Thus, the Grid is transformed into a LambdaGrid. A number of physics and astrophysics data-intensive project are prime candidates to drive this development.

- 16. Campus Infrastructure is the Obstacle “ Research is being stalled by ‘information overload,’” Mr. Bement said, because data from digital instruments are piling up far faster than researchers can study. In particular, he said, campus networks need to be improved. High-speed data lines crossing the nation are the equivalent of six-lane superhighways, he said. But networks at colleges and universities are not so capable . “ Those massive conduits are reduced to two-lane roads at most college and university campuses,” he said. Improving cyberinfrastructure, he said, “will transform the capabilities of campus-based scientists.” --Arden Bement, director National Science Foundation, Chronicle of Higher Education 51 (36), May 2005. http://chronicle.com/prm/weekly/v51/i36/36a03001.htm

Editor's Notes
- Logo overlaps SIO text (fix)
- There are a number of efforts across the globe and at every level of networking—from individual institutions to international and trans-oceanic--to develop and deploy optical networking infrastructure that is controlled and managed by and for the Research and Education community. [The graphic looks fuzzy to me, so I’m guessing this is where we’ll drop in the rings graphic the designer is developing.]
