Ethernet devices must allow a minimum idle period between transmission of Ethernet packets. [1] A brief recovery time between packets allows devices to prepare for reception of the next packet. While some physical layer variants literally transmit nothing during the idle period, most modern ones continue to transmit an idle pattern signal.
Wireshark screenshot of an Ethernet pause frame. Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The goal of this mechanism is to avoid packet loss in the presence of network congestion. The first flow control mechanism, the pause frame, was defined by the IEEE 802.3x ...

The wire speed should not be confused with the line bitrate, also known as gross bit rate, raw bitrate or data signalling rate, which is 125 Mbit/s in fast Ethernet. In case there is a physical layer overhead, for example due to line coding or error-correcting codes , the line bitrate is higher than the wire speed.
However, Ethernet is designed to be a best-effort network that may experience packet loss when the network or devices are busy. In IP networks, transport reliability under the end-to-end principle is the responsibility of the transport protocols, such as the Transmission Control Protocol (TCP). One area of evolution for Ethernet is to add ...
