This report adresses a rate-based feedback approach to congestion control in Frame Relay (FR) networks. The control is realized according to two FR frame headers's bits. Forward Explicit Congestion Notification (FECN) bit and Backward Explicit Congestion Notification (BECN) bit. A node which reaches its maximum storing capacity is called "congested". This situation can be due to the saturation of its processors or one or more of its outgoing transmission links. In this report, we present two differents models for two kinds of priority traffic. The first model concerns the arrivals of fixed length frames and the second one the arrivals of variable length frames. In addition, we give some reflections about control parameters, particularly, control interval parameter.
