Computer Network: Congestion Control with Frame Relay Interface Ports
There are two types of congestion notification used to control station transmission rates; Explicit
• Explicit Congestion notification is done by the attached network sending frames to the Frame Relay Interface station with the Backward Explicit Congestion notification (BECN) bit set in the frame header. This notifies the Frame Relay Interface station that the network is congested for the corresponding DLCI. Frame Relay Interface stations can be configured to respond to Explicit Congestion notification.
