Special Features:
PITT, PSC JOIN NATIONAL LambdaRail
The Pittsburgh Supercomputing Center (PSC) and the University of Pittsburgh
have joined a consortium of leading U.S. universities and companies deploying
an advanced, nationwide fiber-optic infrastructure. PSC and Pitt share
membership and a seat on the board of National LambdaRail (NLR) -- a national
network infrastructure supporting experimental and production networks for the
U.S. research community.
NLR's mission is to deploy national networking infrastructure to foster
advanced networking research and to encourage next-generation applications in
science, engineering and medicine. Through advanced technologies, it will make
available multiple experimental and production networks for the U.S. research
community. Through NLR, many different networks will exist side-by-side in the
same fiber-optic cable, but will be independent of each other, each supported
by its own lightwave or lambda.
"NLR pushes beyond existing limitations of conventional Internet backbones,"
said PSC director of networking Wendy Huntoon. "This will allow us, for
instance, to create a dedicated connection for a specific purpose, such as to
support rapid data transfers between PSC and Oklahoma for a tornado
forecasting experiment."
"The NLR initiative presents an exciting opportunity for university faculty
engaged in advanced networking research as well as those faculty whose work
involves next generation network application research," said Jinx Walton,
director of computing services and systems development at the University of
Pittsburgh. "The availability of a national scale network committed to
fostering research activities will create opportunities that are impossible on
production networks. "
"The Pittsburgh Supercomputing Center and the University of Pittsburgh are
welcome and valued additions to the NLR membership," said Tracy Futhey, chair
of the NLR Board of Directors. "Their membership is especially gratifying
because PSC was one of the earliest advocates of National LambdaRail, which is
committed to deploying and using the most advanced national networking
infrastructure in the United States dedicated to research and education. As
acknowledged network leaders, the NLR will benefit greatly from their
participation."
The connection to NLR is implemented at PSC's Three Rivers Exchange (formerly
the Pittsburgh GigaPoP), a high-speed network crossroads connecting regional
academic institutions, businesses and government agencies to next-generation,
national network backbones such as NLR.
Using dense wave-division multiplexing, the pair of fiber-optic cables
connecting Pittsburgh to NLR can be split into up to 40 lambdas, each capable
of moving data at 10 Gb per second. NLR will initially use four channels to
implement four separate nation-wide networks dedicated to experimentation with
new network technologies and applications.
Three lambdas on the NLR infrastructure between Pittsburgh and Chicago are
currently used for a 30 Gb per second link between PSC and the TeraGrid, a
multi-year National Science Foundation effort to build and deploy the world's
largest, most comprehensive distributed infrastructure for open scientific
research.
