A method of flow control in which a receiver gives a transmitter permission to transmit data until a window is full. When the window is full, the transmitter must stop transmitting until the receiver advertises a larger window. [5] Sliding-window flow control is best utilized when the buffer size is limited and pre-established.
Software flow control is a method of flow control used in computer data links, especially RS-232 serial. It uses special codes, transmitted in-band, over the primary communications channel. These codes are generally called XOFF and XON (from "transmit off" and "transmit on", respectively). Thus, "software flow control" is sometimes called "XON ...
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 standard.

If the link layer receiver detects a CRC error, the receiver notifies the transmitter via a flit on the return link of the pair and the transmitter resends the flit. The link layer implements flow control using a credit/debit scheme to prevent the receiver's buffer from overflowing. The link layer supports six different classes of message to ...
