Bandwidth Tests From Daya Bay to IHEP and NERSC

These tests are being done as part of the data movement challenges for Daya Bay.

Bandwidth tests to IHEP and NERSC.

This is a graph showing the achived speed (in Mbps) of raw network performance. This data is being tested using iperf. These tests are being used to baseline the bandwith of the network. The tests are running every 4 hours. Shown is both the raw data points.

The command is: iperf -w 1500K -c iperf.nersc.gov -P6 -t 30


The blue line is is the data rate from Daya Bay to IHEP in Beijing.
The red line is the data rate from Daya Bay to NERSC in California.
