【Abstract】 Describing the end-to-end burst loss characteristics by Gilbert loss model, the model of RFC6675-based fast retransmission was proposed and recovery and a throughput model of TCP SACK based on the fast retransmission and recovery model was derced. The numerical and network simulations show that the fast retransmission and recovery model can accurately describe the fast retransmission and recovery process, the estimation accuracy of throughput model was promoted.更多还原
