Re: TCP and Loss (inherently lossy nets)

Can anyone from Packet Radio or SURAN projects speak to the retransmission
attempts done on single hops to improve reliability (and increase delay
average and variance)? Is hop-by-hop retransmission better than end-to-end
retransmission or not? Why? Should TCP rely on hop-by-hop reliability and
never retransmit? (Before you answer that, recall that the vast majority of
lost packets are dropped in gateways because of congestion.)

     I'm interested in situations in which loss is inherent -- that
     is, you will get loss, no matter what your TCP does. Packet radios
     suffering from noise or jamming are good examples. Loss caused by
     congestion is a different problem.
