What & Why of NextGen Optical
Networking
• Customer-controlled fiber and/or lambdas
• Opportunities for more bandwidth, noncontention-based bandwidth & and breakable
research networks
• Lower marginal costs of expansion by adding
lambdas
• Platform for new networking research
(connection-oriented) using lambda-switching
• Leverages unique market conditions: availability
of fiber and optical equipment

A Few Access Grid “AG” Facts
– Developed by the Futures Laboratory at Argonne
National Laboratory
– Deployed by the NCSA PACI Alliance
– The Access Grid is now in use at over 160 institutions
worldwide

Why Does It All Matter?
• Our researchers need to be full members of
all local, regional, national & international
communities of interest
• For many, this already requires highperformance connectivity from the desktop
to the world
• (For others, it will soon)
8/12/03
Optical networks for demanding
collaborative applications – beyond
Internet2
• Several applications at MSU that demand high
bandwidth connectivity, low latency, remote
computation, real-time visualization:
– CCB: Neuroscience application requiring distributed
processing, remote real-time access to multiple,
distributed data sets
– Solar Physics: Satellite operations, Virtual Solar
Observatory
– Ag Science: Multi-state program involving remote
sensing data, visualization
– INRA Subsurface Soil Science PhD program

Start with the campus
• 100Mbps switched to the desktop
– More for specialized apps, 10Mbps switched where
necessary and accept its limits
– Drive at least to a fiber-based distribution system

•
Multicast required for many apps
Tune key servers & clients!
Wireless for ubiquity & mobility
Bandwidth management where needed

Key Intra-State Networking Strategies
• Technologies

–
Dark fiber -- where possible
High-speed leased services
Microwave
Emerging & non-emerging wireless approaches
Satellite
• Procurement Approaches
–

–
Leverage regulatory capabilities
Buy
Lease
“Partner” with vendors
• Collaborate with: K12? State? Feds? Museums?
Problems are regionally idiosyncratic
8/12/03
Staying Connected!
• National initiatives are moving quickly and
often exclude “us”
• We need to learn from what they’re doing and
apply lessons where we can
• We need more help both from within and
without
Problems are regionally idiosyncratic but
national in scope

Proposals submitted to NSF and NCRR to enable Montana to participate
in main stream e-science
8/12/03
Western BRIN InfoNet Proposal
Submitted to NCRR in July
• Develop and implement a plan that will
provide a high-speed telecommunications
network for biomedical researchers in the
group of six rural states currently on the
other side of the geographical digital divide
• Alaska, Hawaii, Idaho, Montana, Nevada,
and Wyoming

Western BRIN InfoNet Proposal
Plans for Montana
• Connect the Montana State University network
to the Internet2 backbone in Seattle with highspeed fiber
• Add Access Grid node capability dedicated to
BRIN-related activities and engineered to
interoperate effectively with other BRIN and
Grid AGNodes
• Work with other in-state campuses to provide top
quality end-to-end performance for BRIN
resources including Access Grid Nodes

Research Projects - examples
• Bioinformatics Grid, led by Sherrilynne Fuller at
the University of Washington
• BIRN Project, a grid-based distributed
collaborative environment for brain imaging data
led by Mark Ellisman at U.C. San Diego
• NeuroSys Project, a data management system
that allows individual researchers to annotate,
query and share data led by Gwen Jacobs at
Montana State University
• Plus others……

“Now here you see, it takes all the
running you can do to keep in the
same place. If you want to get
somewhere else, you must run at
least twice as fast as that!”
