Correlations between FTP throughput, Hops & Packet Loss

In order to get some idea of how FTP throughput rates (kB/sec) correlate with ping response time, and packet loss and against the number of hops (as measured by traceroute) we have measured these metrics between SLAC and several SLAC collaborator nodes. We then plot the FTP throughput versus hop count and versus ping packet loss and versus ping response time. The results are shown below.

It can be seen that there are strong correlations with response time and packet loss. The correlation with hop count is less pronounced.
