Frame Relay Frame Structure

• Congestion Control

  • Traffic shaping (see Chapter 8)

• The Backward Explicit Congestion Notification (BECN) bit is set to tell the station that receives the frame to slow down; This is easy to implement

• The Forward Explicit Congestion Notification (FECN) bit is more complex; If a station receives this notification in an incoming frame, it should tell its communication partner at the other end of the Frame Relay network to slow down
