This document provides the entry point to the set of documentation on
a new Congestion Exposure (ConEx) protocol. It motivates a new ConEx
field at the IP layer, focusing on the 'why' rather than the 'how'.
In the absence of such a protocol, traffic is subjected to numerous
traffic management checks and limits as it crosses the Internet. The
purpose of this protocol is to expose congestion to network
operators, so that they have no need to intervene at all when there
is no congestion, and so they have exactly the right information when
there is congestion. Then it will at least be possible for traffic
management to be application-neutral, openly transparent and free of
unnecessary restraints. Although traffic management is the focus of
this document, it also briefly introduces a number of other important
potential uses for ConEx, demonstrating its role as a generative
technology and justifying its placement in the IP layer.
