CHICAGO: A test
conducted by two Chicago computer scientists to push trans-Atlantic
high-speed data transmission has resulted in a new top speed of 2.8
gigabits (billion bits) per second.
Mambretti, director of the International Center for Advanced Internet
Research at Northwestern University, and Robert Grossman, director of the
Laboratory for Advanced Computing and National Centre for Data Mining at
the University of Illinois at Chicago, set the speed mark during a
presentation in Amsterdam at iGRID 2002, a biennial conference held to
showcase new applications over high-performance networks.
Mambretti and Grossman
developed a novel technique they call Photonic Data Services (PDS) to send
gigabyte amounts of data at speeds more than 500 times faster than the
standard protocol now used to send data over the Internet.
PDS layers and
integrates four network protocols to fully use network capacity at maximum
speeds. The application may prove especially effective for data
mining, a research technique used for managing extremely large volumes of
these protocols, it is now possible to analyse gigabytesize data sets
anywhere in the world," said Grossman.
"PDS allows an
application to create specialised, high-performance network connections on
demand," said Mambretti.
"For the first
time these types of connections will be available to large-scale global
applications." Mambretti and Grossman said this type of data
communication service could benefit several businesses and research
fields, including bioinformatics, financial services, geosciences,
computational research and industrial design.
They said their
technique would enhance performance and management of information
transmission on national, international and global networks.
The transmission test
linked Amsterdam to Chicago using a state of the art optical connection
called NetherLight, part of the Dutch research network SURFnet, and the
Chicago-based StarLight, a switch/ router optical network facility built
for high-performance research applications.
