Abstract Congestion control schemes have been important techniques in the long-distance transmission such as a radio environment and video stream communication. In order to provide highly efficient packet communication, High-performance and Flexible Protocol (HpFP) has been researched. HpFP has the character that throughput is adjusted by changing a packet transmission interval. We have discussed some reliability models of a window flow control scheme based on a packet transmission interval. We have proposed one of models that a packet transmission interval is prolonged if a constant number of packets has failed at a first time transmission, and the other that the server checks the state of network congestion during connection by Explicit Congestion Notification (ECN) and if ECN bit has been set, a packet transmission interval is prolonged. This paper considers a stochastic model of a window flow control scheme based on a packet transmission interval with ECN considering packet loss. That is, the server checks ECN bit during connection and if the server detects the network congestion, the server executes congestion control that a packet transmission interval is prolonged. Thereafter, if the retransmission has failed at constant number, or a constant number of packets has failed, the server checks it again. The mean time until packet transmissions succeed is derived, and an optimal policy is discussed analytically.
