Definitions for "Forward explicit congestion notification"
Keywords:  becn, fecn, congestion, relay, sender
A flow control method used in Frame Relay to advise the sender that upstream network resources are busy.
Where a bit in the overhead of a data packet in a frame relay network is set 1 if the packet travels through network congestion in the same direction it is flowing, that signals the network to higher level protocols to take flow control action. Example - Done to keep the data packet flow from exceeding the CIR for the connection, and a counterpart to BECN.
A bit in the Frame Relay header that is set when the network router has detected congestion in the destination direction (or "foreward," from the packet's point of view). See also Backward Explicit Congestion Notification (BECN).
