      <abstract>
	 <t>   This memo specifies a forwarding method for bounded latency and
   bounded jitter for Deterministic Networks and is a variant of the
   IEEE TSN Cyclic Queuing and Forwarding (CQF) method.  Tagged CQF
   (TCQF) supports more than 2 cycles and indicates the cycle number via
   an existing or new packet header field called the tag to replace the
   cycle mapping in CQF which is based purely on synchronized reception
   clock.

   This memo standardizes TCQF as a mechanism independent of the tagging
   method used.  It also specifies tagging via the (1) the existing MPLS
   packet Traffic Class (TC) field for MPLS packets, (2) the IP/IPv6
   DSCP field for IP/IPv6 packets, and (3) a new TCQF Option header for
   IPv6 packets.

   Target benefits of TCQF include low end-to-end jitter, ease of high-
   speed hardware implementation, optional ability to support large
   number of flow in large networks via DiffServ style aggregation by
   applying TCQF to the DetNet aggregate instead of each DetNet flow
   individually, and support of wide-area DetNet networks with arbitrary
   link latencies and latency variations as well as low accuracy clock
   synchronization.
