UERJ transmits data to Pittsburgh at 400 Mbps, at least

RIO DE JANEIRO, Brazil - November 5, 2004 - The State University of Rio de
Janeiro (UERJ) and the Brazilian National Research and Education Network
(Rede Nacional de Ensino e Pesquisa – RNP) have promised to break the record
of data transmission speed between Brazil and the United States. On November
11th, from midnight to one a.m. (Brasília time), the laboratory of High
Energy Physics at UERJ plans to transmit around 180 gigabytes of data (which
is equivalent to more than 250 CDs) to Pittsburgh, USA. The demonstration
will be made during the High Performance Computing, Networking and Storage
Conference (SC2004), a supercomputing conference to be held from November 6th
to 12th.

The data will leave a computer at UERJ and will travel a long way until they
get to Pittsburgh, passing by at least four networks in Brazil, Europe and
the United States: the Brazilian experimental Giga Project Network, the Latin
American Clara Network, the European Géant and the North American Abilene,
part of the Internet2 project. The first two have RNP’s participation.

Rehearsing for 2007

Besides the transmission, there will be a computational grid experiment
between the equipment at UERJ and that in Pittsburgh. The grid is an
infrastructure that permits the integrated and collaborative use of
computers, networks, database and scientific instruments. The structure
assembled at UERJ’s laboratory has 100 computers, which will be used to
process jobs sent from Pittsburgh.

This demonstration will be a rehearsal for the participation of Brazil in the
experiments with the new subatomic particle accelerator of the European
Center of Nuclear Research (Cern, from the French Conseil Européen pour la
Recherche Nucléaire), which should start functioning in 2007. The grid
technology was the solution chosen to deal with the great amount of
information which will be produced by the particle accelerator (20 petabytes
per year, approximately the same as 28 million CDs).

Both experiments are being coordinated by professor Alberto Santoro, from the
Institute of Physics at UERJ. In order to make them possible, the
collaboration of Embratel, Intelig, Telemar and Telefônica has been
fundamental - contributing with the fibers of Giga Project network, as well
as that of Clara organization (Latin American Cooperation of Advanced
Networks), which permitted using the capacity of Clara Network that still
hasn’t been used. In addition to the aforementioned organizations,
technicians from the engineering units of Giga Project at RNP, CPqD, Clara
Network and Géant are also involved.

About the networks involved

UERJ is directly connected to Giga Project’s network, an experimental optical
infrastructure coordinated by RNP and the Center of Telecommunications
Research and Development (Centro de Pesquisa e Desenvolvimento em
Telecomunicações - CPqD). Giga Network was connected to Clara Network through
its point of presence in Brazil, located in São Paulo, specially for the
experiments of the laboratory of Physics.

Clara Network interconnects national academic networks of Latin American
countries at speeds of up to 155 Mbps. RNP represents Brazil in the
consortium, being part of the central ring of the network. The connection
abroad is possible due to a 622 Mbps link with Géant, the European academic
network. The construction of Clara network and its connection with Europe
occurred thanks to the support of the European Community, by means of Alice
project (Latin America Interconnected to Europe).

As it happens with Clara Network in Latin America, Géant interconnects
several national academic networks in Europe and is also connected to
academic networks in other parts of the world, among which we may cite
Abilene, the major Internet2 project backbone, in the United States. From
Abilene, we can get to the site of the event, the David L. Lawrence
convention center, in Pittsburgh, Pennsylvania.

About SC2004

SC2004 is the premier international conference on high performance computing,
networking and storage. Founded in 1988, this conference series has grown to
now include scientists, researchers, software developers, policy makers,
corporate managers, CIOs and IT administrators from universities, industry
and government. Attendees become immersed in the latest state-of-the-field
developments in technology, applications, vendor products, research results,
national policy and national/international initiatives. SC2004 is the one
place attendees can see tomorrow’s technology being used to solve world-class
challenge problems today.
