Abstract:
   This specification defines a framework for coupling the Active Queue
   Management (AQM) algorithms in two queues intended for flows with
   different responses to congestion.  This provides a way for the
   Internet to transition from the scaling problems of standard TCP
   Reno-friendly ('Classic') congestion controls to the family of
   'Scalable' congestion controls.  These are designed for consistently
   very Low queuing Latency, very Low congestion Loss and Scaling of
   per-flow throughput (L4S) by using Explicit Congestion Notification
   (ECN) in a modified way.  Until the Coupled DualQ, these scalable L4S
   congestion controls could only be deployed where a clean-slate
   environment could be arranged, such as in private data centres.

   The specification first explains how a Coupled DualQ works.  It then
   gives the normative requirements that are necessary for it to work
   well.  All this is independent of which two AQMs are used, but
   pseudocode examples of specific AQMs are given in appendices.
