Transport protocol selective acknowledgements analysis in loaded transmission data path
A mathematical model of the transport protocol with selective acknowledgements for multi-hop transmission data path with queues is proposed. The protocol behavior is modeled through the two-dimensional Discrete-Time Markov chain which is used for estimation of transport connection throughput. The model takes into account the influence of window size, retransmission time out, probability of packet loss and queue size on transport connection throughput. Probabilities of Markov chain states are found. Analytical expressions of bandwidth available for transport connection in different load conditions were obtained. Analysis of transport protocol throughput for different protocol parameters and transmission data path conditions has been conducted.
