Abstract

The transmission control protocol (TCP) retransmission timeout (RTO) is calculated based on a round-trip time (RTT) with weighted smoothing. This algorithm is sensitive to the initialization, and convergence is slow. The RTO changes lagging behind the RTT. The algorithm only takes into account the size of RTT, without considering the tendency of it. But the changing trend of RTT more directly reflects the traffic state of network. This paper is based on the traditional RTO algorithm; both the size and the change trend of the RTT are considered. Modify the weight coefficient, the weight coefficients of adaptive changes of RTT, so that RTO can quickly follow the changes of RTT.
