Consider this: A downloads a file from D thus using D-b-A (with 50% packet loss). But each packet has to be acknowledged and every second acknowledgement is also lost (via A-c-D) . That is why D will resend every second packet and the throughput will suffer even more. I think we should find a solution here but up to now I don't have a clue how to do it. Regards, Marek
