Amendment 17: Priority-based Flow Control

Approved 16 June 2011


Abstract: This amendment to IEEE Std 802.1Q-2011 specifies protocols, procedures, and managed objects that enable flow control per traffic class on IEEE 802® point-to-point full duplex links. This is achieved by a mechanism similar to IEEE 802.3 Annex 31B PAUSE, but operating on
individual priorities.
