DEISA decrease in throughput between IDRIS and other sites

PTS Case 9

Synopsis

Beginning in October, DEISA observed a decrease in the achievable throughput (as measured by iperf) between IDRIS and their other sites; pre-October 800Mbps was the norm, after October this fell to 600-640Mbps.
The PERT’s investigation determined this decrease in throughput was entirely due to the routing changes in the international backbone network that occurred as a result of the migration from the G�ANT to G�ANT2 networks. Once the new G�ANT2 CH-FR link became operational (a few weeks later than planned), the measured throughputs returned to their normal, high levels.
