[Winpcap-users] TCP Retransmission

[ceo]

Thanks,
Regarding the extra bytes, since the receiver may or may not already 
processed the original packet before receiving the retransmitted one, he 
should treat only the extra byte as a new data and neglect the duplicated 
data. Another alternative would be to neglect the original packet (though it 
may have already been processed) and treat only the retransmitted one.
Which approach is actually common?

Regards
