Backward Explicit Congestion NotificationºóÏòÏÔÊ1/2
Part of the explicit congestion notification (ECN) technique used in frame relay networks. The BECN is a one-bit field containing data sent by a frame relay assembler/disassembler (FRAD) on the receiving end of a transmission backward to the FRAD on the transmitting end. This data alerts the transmitting FRAD that there is congestion on the line, and that network resources are insufficient to support transmission at the current rate. See ECN and FRAD.
A bit set by a Frame Relay network to notify an interface device (DTE) that congestion avoidance procedures should be initiated by the sending device.
A Resource Management (RM) cell type generated by the network or the destination, indicating congestion or approaching congestion for traffic flowing in the direction opposite that of the BECN cell.
Backward Explicit Congestion Notification. A bit in the Frame Relay header that is set when the network router detects congestion from the source direction (or "backward," from the packet's point of view). See also Forward Explicit Congestion Notification (FECN).
See Backward Explicit Congestion Notification (BECN).
Backward Explicit Congestion Notification. A flow control method used in Frame Relay to advise the sender that upstream network resources are busy.
Backward Explicit Congestion Notification. Within a data packet, an overhead bit traveling in a frame-relay network. Bit is set to one if the packet travels through an area of network congestion that is opposite of its flow, signaling to higher level protocols to take flow control action.
Backward Explicit Congestion Notification. A BECN is sent to the sender of Frame Relay traffic to indicate that congestion was detected. It is the sender's responsibility to implement congestion avoidance procedures.
ackward xplicit ongestion otification is a bit set in a Frame Relay network to notify a DTE device that congestion is occurring and that the sending device should be notified to initiate congestion procedures.
Backward Explicit Congestion Notification. A Frame Relay method where ANSI Annex D management notifies the source device that it is receiving more frames than the Frame Relay backbone can process. This results in congestion at the router.
Backward explicit congestion notification. In a Frame Relay network, a header bit transmitted by the destination device requesting that the source device send data more slowly. BECN minimizes the possibility that packets will be discarded when more packets arrive than can be handled. See also FECN.
backward explicit congestion notification. Bit set by a Frame Relay network in frames traveling in the opposite direction of frames encountering a congested path. DTE receiving frames with the BECN bit set can request that higher-level protocols take flow control action as appropriate. Compare with FECN.
Backward explicit congestion notification. Bits within a frame relay header to indicate congestion in the path in the opposite direction as the frame is flowing. See also FECN.
