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

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 interdomain photonic-switched networks

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.
GigE = Gigabit Ethernet (Gbps connection type)
