Measurement of UDP throughput with UDP_MON
on a series of configurations which compares a dedicated lambda with the regular Internet.

For details about setup and measurements see: http://www.science.uva.nl/~jblom/lambda/udp_bw_mon_large/

The first row in this display is the reference, with a dedication trans-Atlantic connection. The two other rows measure the results over the regular Internet.
