The correct answer is C.
n a link layer network such as Frame Relay, the network sends messages with the forward
explicit congestion notification (FECN) or backwards explicit
congestion notification (BECN) if there is congestion. With the DTS feature, the
traffic
shaping adaptive mode takes advantage of these signals and adjusts the
traffic descriptors. This approximates the rate to the available bandwidth along the
path.
FECN as use to inform of the available bandwith.
