ESnet Strategy Is Meeting Increasing Demand for Scientific
Networking
As part of its long-term plan to increase both bandwidth and
reliability, DOE's Office of Science Energy Sciences Network
-- better known as ESnet -- has just completed increasing
the bandwidth to a number of research sites. Links to Brookhaven
and Oak Ridge national labs have been upgraded to 2.5 Gpbs,
the link to CERN LHC data network to 10 Gbps, and at multiple
locations to Abilene (Internet2's high-speed network) to 2.5
and 10 Gbps.
The upgrades
follow an ESnet strategy unveiled last month to replace ESnet's
spoke-and-hub architecture with "metropolitan area network"
rings and a new national ring, increasing both bandwidth and
reliability. The plan was presented as part of a comprehensive
review of the ESnet project by DOE and to the ESnet Steering
Committee. Managed by Berkeley Lab, ESnet connects 40 sites
nationally and provides high-speed connectivity for DOE collaborations
with the U.S. research and education community and collaborations
with the international science communities in Europe and Asia.
