disciplines to analyze, model, simulate, and predict complex
physical, chemical, and biological phenomena important to the
Department of Energy (DOE).
Research:
Foster and support fundamental research in advanced scientific
computing – applied mathematics, computer science, and
networking
Facilities:

Roadmap –
Requirements/Business Case
Office of Science
 Over 40% of federal support to the physical sciences is in
the Office of Science
 Supports over 15,000 PhDs, PostDocs and graduate students.
 A similar number of PhDs, PostDocs and graduate students
funded by other federal, state and private agencies, and
international institutions are users/collaborators of DOE
facilities.
 Most of these users/collaborators and many of the DOE funded
users are at universities; many of them are at international
locations.
 Effective end-to-end (E2E) networking and middleware that
interfaces to university researchers and international
collaborators is critical for the success of the DOE Science
Mission.
U.S. Department of Energy
Roadmap –
Requirements/Business Case
Office of Science
 Achieving the DOE science mission for the next five years
requires continuing advancements in networking and
middleware.
 THE #1 DRIVER – Petabyte scale experimental and simulation
data systems will be increasing to exabyte scale data systems.
 Examples: Bioinformatics, Climate, LHC, etc.
 Computational systems that process or produce the data continue
to advance with Moore’s Law thereby driving network
requirements.
 The combination of increases in data and computational power are
projected to at least continue the historical trend of doubling
network requirements every year.
U.S. Department of Energy
Roadmap –
Requirements/Business Case
Office of Science
 The sources of the data, the computational resources and
the scientists consumers of the data are often not
collocated. This is due to two main reasons:
 The experimental facilities, data facilities and computational
facilities are extremely expensive and consequently not replicated.
They are also distributed. Sharing them is often the only cost
effective solution.
 The scientists are highly distributed, many of them being located
at universities.
 Due to the distribution of experimental facilities, data
facilities, computational facilities and scientists,
networking and middleware are essential to achieve the
science.

Network Issues –
Technology
Office of Science
 Single wavelengths in the optical fiber transport can currently
only carry 10 Gbps and this limit is not anticipated to change
within the next five years. At least 40 Gbps will be required by
2008.
 The current transmission protocol, TCP, will not at present
efficiently support speeds above a few Gbps per data stream.
 The technologies to concurrently control multiple multi Gbps
data streams do not at present exist.
 The technologies to perform effective cybersecurity above
several Gbps do not currently exist.

…what now???
Office of Science
VISION - A scalable, secure, integrated network environment for ultra-scale
distributed science is being developed to make it possible to combine resources
and expertise to address complex questions that no single institution could manage
alone. It is creating the means for research teams to integrate unique and
expensive DOE research facilities and resources for remote collaboration,
experimentation, simulation and analysis.
 Network Strategy
Production network
 Base TCP/IP services; +99.9% reliable
High-impact network
 Increments of 10 Gbps; switched lambdas (other solutions); 99% reliable
Research network
 Interfaces with production, high-impact and other research networks; start electronic and
advance towards optical switching; very flexible

Revisit governance model
 SC-wide coordination
 Advisory Committee involvement
