TransLight Tom DeFanti 50 years ago, 56Kb USA to Netherlands cost US$4.00/minute Now, OC-192 (10Gb) costs US$2.00/minute* That’s 400,000 times cheaper *if you buy it for 525,600 minutes and manage it yourself

TransLight is for e-Scientists who Need Multi-Gigabit Networking Computer scientists and engineers Networking engineers High-energy physicists Astronomers Geoscientists Biomedical Informatics researchers Emergency Response researchers Computational astrophysicists Focus on scheduled, deterministic networking

What is a Lambda? A lambda is a pipe where packets can be inspected as they enter and exit, but not when they are in transit. In transit, only the parameters of the lambda (e.g., color, bandwidth) matter TransLight proposes ~40 1GigE lambdas for the one-year experiment 10GigE lambda research will be encouraged as well

TransLight is an Experimental Network to Provide global lambdas for scheduling Build more hubs with switches, co-location space and fiber access like StarLight and NetherLight Develop a TransLight Governance Board to create policy for scheduling circuits –Initial members are from networks providing schedulable GigE circuits to the TransLight project: CANARIE, CERN/DataTAG, StarLight/Euro-Link, and SURFnet, with others to be invited soon –Its effectiveness will be evaluated and provide helpful input toward the high-level management of future inter- domain photonic-switched networks

Optical Switching at StarLight and NetherLight for The OptIPuter N E T H E R L I G H T A “groomer” is a box that accepts multiple circuits of varying types (e.g., 1GigE, OC-48) and aggregates and/or disseminates over the 10Gbps transoceanic link. As the amount of transoceanic connectivity increases, we aim to “bandwidth match” the amount of data being sent and/or received by clusters across continents, a long-term goal of the OptIPuter Large ITR project.
