RTO prediction algorithm based on a least mean square filter

The retransmission timeout(RTO) prediction algorithm that current the transmission control protocol uses is too sluggish to respond to changes in the round-trip time(RTT).Furthermore,the predicted values are usually much larger than real RTTs,leading to reductions in the bandwidth utility ratio.A prediction algorithm based on a least mean squares filter was developed to predict better values.The algorithm performance was evaluated using a variety of typical websites.The results show that the algorithm quickly stabilizes,has a very small prediction error,and quickly responds to RTT changes,so it can improve transmission performance.
