Abstract The internet that attains long-distance transmission has been required for a highly reliable communication. For example, cloud computing has been executed by the long-distance transmission between client and cloud server. Recently, a problem of reduction in transmission efficiency is caused by a packet loss from network congestion. In order to solve the problem, High-performance and Flexible Protocol (HpFP) has been proposed in a communication protocol. HpFP has been realized highly transmission efficiency in communication protocol which performs congestion control on a packet loss. Throughput has control by changing a packet transmission interval. This paper considers a stochastic model of a window flow control scheme based on a packet transmission interval. If retransmission from a packet loss has been occurred at k times, a packet transmission interval is prolonged. We derive the mean time until packet transmissions succeed, and analytically discuss an optimal policy which maximizes the amount of packets per unit of time until the transmission succeeds. Finally, numerical examples are given.
