Ethernet flow control : ウィキペディア英語版 | Ethernet flow control
Ethernet flow control is a mechanism for temporarily stopping the transmission of data on Ethernet family computer networks. The first flow control mechanism, the PAUSE frame, was defined by the IEEE 802.3x standard. The follow-on priority-based flow control, as defined in the IEEE 802.1Qbb standard, provides a link-level flow control mechanism that can be controlled independently for each Class of Service (CoS), as defined by IEEE P802.1p. The goal of this mechanism is to ensure zero loss under congestion in data center bridging (DCB) networks. ==Description== Ethernet is a popular family of computer network protocols. Flow control can be implemented at the data link layer. A sending station (computer or network switch) may be transmitting data faster than the other end of the link can accept it. The first flow control mechanism, the PAUSE frame, was defined by the Institute of Electrical and Electronics Engineers (IEEE) task force that defined full duplex Ethernet link segments. The IEEE standard 802.3x was issued in 1997.
