When that mismatch lasts long enough, receive buffers fill and frames may be dropped.</p> <p>IEEE 802.3x flow control provides a link-level response for full-duplex Ethernet. A device can send a MAC Control PAUSE frame that asks its directly connected peer to stop transmitting ordinary data frames for a specified interval. The pause is temporary, local to that link, and different from congestion control performed by higher-layer protocols.</p>
