Abstract	The loss of retransmitted segments leads to sub-optimal TCP performance, because these segments, generated by the fast retransmit algorithm and the response of partial ACK under fast recovery, are not well handled in conventional TCP. This paper introduces an algorithm to recover these lost retransmissions for NewReno TCP and details the steps to implement it. It provides careful retransmission by considering the loss of unacknowledged segments. The algorithm is followed by two options for restoring the congestion control state; both reduce the moderate transmission rate which mitigates network congestion, ns2 simulations show that the algorithm can overcome the loss of retransmitted segments. Moreover, it also suppresses the unnecessary throughput degradation more effectively than NewReno TCP. The options for restoring the congestion control state also show adequate performance under retransmitted segment loss
