Abstract :
In order to improve the TCP performance, we expand the TCP protocol by making sender known what is packet reordering and loss to reduce unnecessary \´overtime retransmitted" and "fast retransmit". Based on CETEN (cumulative explicit transport error notification), a new method RR-CETEN (reorder robust-CETEN) is proposed. This mechanism can improve the precision of LEAST (loss estimation algorithms for TCP) and make CETEN more robust. The method shows efficiently in experiments that it can advance throughput by 14%-42% and decrease unnecessary retransmit near 2 times
