Flow control enables connected Ethernet ports to control traffic rates during congestion by
Usage
allowing congested nodes to pause link operation at the other end. If one port experiences
congestion, and cannot receive any more traffic, it notifies the other port to stop sending until
the condition clears. When the local device detects congestion at its end, it notifies the remote
device by sending a pause frame. On receiving a pause frame, the remote device stops sending
data packets, which prevents loss of data packets during the congestion period.

sending traffic.
