Technical Summary
The PCN mechanism in routers in the interior of a PCN domain marks
packets when certain configured rates are exceeded. The PCN working
group explored a number of approaches for encoding this pre-congestion
information into the IP header. This document describes the various
approaches that were examined and discusses the constraints that had
to be satisfied by a viable encoding mechanism.

RFC Editor Note
4.5 says RFC5696 was published as a draft Internet Standard. This is confusing, given the existence of the "Draft Internet Standard" status. RFC5696 is a Proposed Standard. Please reword to: "The baseline encoding described in section 4.1 is defined in [RFC5696]."
