UDP-based protocols did not perform well for most of the RTTs we tested. GridFTP with
UDT performed poorly for most of the RTTs. Although its author claims that UDT is more
efficient with increasing RTT, the rate of decreasing throughput for increasing RTT from 0 to
100 ms was the fastest among all protocols tested. At RTT 200 ms, UDT was the slowest among
all the protocols.
Throughput of Tsunami did not decrease much as RTT increased, however its throughput
was the lowest among all four protocols for RTTs less than 200 ms. Tsunami showed through-
put of 0.55 Gb/s across all the RTTs we tested.
GridFTP and ...
