Abstract This paper considers a modified reliability model of congestion control scheme for data transmission. We have discussed some reliability models of a window flow control scheme based on a packet transmission interval. For example, we have proposed one of models that a packet transmission interval is prolonged when packet loss has occurred multiple times, and the other that the above same congestion control scheme is executed with error correcting code for data transmission and so on. These models assumed that packet loss occurs according to a binomial distribution. However, in fact, the probability of packet loss is small. Therefore, the error distribution can be approximated to poisson distribution. In this paper, we considers a stochastic model of a window flow control scheme based on a packet transmission interval with the error distribution considering poisson distribution. That is, packet loss occurs according to poisson distribution and when the transmission fail at a constant number, a packet transmission interval is prolonged. Moreover, when the retransmission has failed at constant number, the server checks it again and the connection is made newly. We derive the mean time until packet transmissions succeed, and discuss an optimal policy analytically.
