This document describes the L4S architecture, which enables Internet
applications to achieve low queuing latency, low congestion loss, and
scalable throughput control. 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 and instead adopt 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.
