Abstract:
   This document describes the L4S architecture, which enables Internet
   applications to achieve Low queuing Latency, Low Loss, and Scalable
   throughput (L4S).  L4S is based on the insight that the root cause of
   queuing delay is in the capacity-seeking congestion controllers of
   senders, not in the queue itself.  With the L4S architecture all
   Internet applications could (but do not have to) transition away from
   congestion control algorithms that cause substantial queuing delay,
   to a new class of congestion controls that can seek capacity with
   very little queuing.  These are aided by a modified form of explicit
   congestion notification (ECN) from the network.  With this new
   architecture, applications can have both low latency and high
   throughput.

   The architecture primarily concerns incremental deployment.  It
   defines mechanisms that allow the new class of L4S congestion
   controls to coexist with 'Classic' congestion controls in a shared
   network.  The aim is for L4S latency and throughput to be usually
   much better (and rarely worse), while typically not impacting Classic
   performance.
