Eifel and F-RTO have been reported representative solutions for spurious TCP timeout. However, these algorithms do not work well in case that delay spike and packet loss occur simultaneously. In this paper, we propose ER-SRTO algorithm which detects the packet loss during delay spike and conducts an efficient recovery in the RTO procedure based on ACK sequence number of retransmission packet. Proposed scheme recovers the lost packet without invoking additional loss recovery procedure. Simulation result shows that proposed algorithm outperforms previous ones.
