The performance of PushPull was found to drop to ~0.5 of the “clean network link” for a packet corruption = 24%. Beyond this point PushPull was not able to transfer files as the tool became unresponsive.

Concurrent file transfer with packet reordering

A peculiar, non-linear, behaviour was found when inducing packet reordering < 4% for concurrent file transfer. These tests were once again repeated but still confirmed this behaviour. In particular from 1 ­-2% an increase is noted in the transfer rate. For packet reordering > 8% a general decreasing trend is noted for the transfer rate. While the transfer rate decreases, it still remains > 30 MB/s indicating that the tool manages packet reordering well with very little variation (or decrease) in performance observed, even for reordering > 80%.

Concurrent file transfer with packet duplication

Packet duplication shows a strong linear trend. Although a decrease in the transfer rate is seen, it is only ~3 MB/s going from 1-80%. . Therefore, PushPull is more than capable to deal with packet duplication.
