|Results with no traffic noise|
|Throughput of GridFTP with TCP (left), GridFTP with UDP (middle), and FDT (right) using|
jumbo frames with increasing RTT and UDP background noise
Here is the test network topology used for the experiments.
The results clearly show that using GridFTP with TCP or FDT gives higher throughput over a 10 Gb/s network link. Even with signi cant level of congestion induced by background noise, FDT was stable enough to perform data transfer. On the other hand, UDP-based protocols did not perform well in most tests. Tsunami is not recommended due to its instability when using jumbo frames or when faced with background noise. Having some background in VoIP (Voice over IP) field where UDP is the king I find it interesting that UDP is not much of a bet in the big data transfer domain.
