From what I have read TCP Fast Retransmission is meant to occur if 3 or more duplicate ACKs are recieved in a row. However I have a trace file where Fast retransmission is occuring after only 2 duplicate ACKs.
Can anyone explain this for me please? Why is there a variation in the number of duplicate ACKs it takes before Fast Retransmission occurs?
I am using a trace file in wireshark. Many thanks.
