The sender side of rdt3.0 simply ignores (i. e., takes noaction
on) all received packets which are either in error, or havethe
wrong value in the acknum field of an acknowledgementpacket.
suppose that in such circumstances, rdt3.0 were tosimply retransmit
the current data packet. would the protocol stillwork? (hint:
consider what would happen in the case thatthere are only it
errors; no packet losses and no prematuretimeouts occur. consider
how many times the nth packet issent, in the limit as n approaches
infinity.
