RFC 3270 defines how to support the Diffserv architecture in MPLS
networks, including how to encode Diffserv Code Points (DSCPs) in an
MPLS header.  DSCPs may be encoded in the EXP field, while other uses
of that field are not precluded.  RFC 3270 makes no statement about
how Explicit Congestion Notification (ECN) marking might be encoded
in the MPLS header.  This document defines how an operator might
define some of the EXP codepoints for explicit congestion
notification, without precluding other uses.  [STANDARDS TRACK]
