Congestion-Control Mechanisms ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Congestion-Control Mechanisms ,[object Object],[object Object],If the network is congested, DCE devices (switches) set the value of the frames' FECN bit to 1. When the frames reach the destination DTE device, the Address field (with the FECN bit set) indicates that the frame experienced congestion in the path from source to destination. The DTE device can relay this information to a higher-layer protocol for processing. Depending on the implementation, flow control may be initiated, or the indication may be ignored.
