	Title		: Emulating Border Flow Policing using Re-ECN on Bulk Data
	Author(s)	: B. Briscoe

Scaling per flow admission control to the Internet is a hard problem.
A recently proposed approach combines Diffserv and pre-congestion
notification (PCN) to provide a service slightly better than Intserv
controlled load.  It scales to networks of any size, but only if
domains trust each other to comply with admission control and rate
policing.  This memo claims to solve this trust problem without
losing scalability.  It describes bulk border policing that emulates
per-flow policing with the help of another recently proposed
extension to ECN, involving re-echoing ECN feedback (re-ECN).  With
only passive, bulk measurements at borders, sanctions can be applied
against cheating networks.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
