fast retranmission will kick in after 3 DUP ACK received by the sender, however in case the tcp segment before the last gets lost, does this mean TCP cannot guarantee to deliver the data ? asked 03 Sep '15, 23:52  hermau edited 03 Sep '15, 23:53 |
One Answer:
You mean if the last segment gets lost I guess (because then there is no segment after the lost segment by which the receiver could detect a loss easily). And no, even if there's no fast retransmission the good old RTO ("Retransmission Time Out") based retransmission will make sure that all segments are transferred until acknowledged. answered 03 Sep '15, 23:58  Jasper ♦♦ |
