P802.1Qdv – Enhancements to Cyclic Queuing and Forwarding
This amendment specifies procedures, protocols and managed objects to enhance Cyclic Queuing and Forwarding, comprising: a transmission selection procedure that organizes frames in a traffic class output queue into logical bins that are output in strict rotation at a constant frequency; a procedure for storing received frames into bins based on the time of reception of the frame; a procedure for storing received frames into bins based on per-flow octet counters; a protocol for determining the phase relationship between a transmitter’s and a receiver’s bin boundaries in time; managed objects, Management Information Base (MIB), and YANG modules for controlling these procedures; and an informative annex to provide guidance for applying these procedures. This amendment also addresses errors and omissions in the description of existing IEEE Std 802.1Q functionality.
