  "An efficient co-operation of EPD with TCP's retransmission strategy has been found to be the key requirement for good TCP over UBR performance with relatively small buffers, compared to the TCP window size. However, in experiments with ... a dominance of timeout, ... EPD has little impact. In this case, only a reduction of the timer granularity ... reduced idle time."
