	Title		: Security Issues for Differentiated Service Framework

This document provides a security analysis for the differentiated
service framework. We studied what kinds of attacks can be performed
and how badly attacks can affect network services under the DiffServ
framework. Without a careful investigation of potential attacks and
impacts, the protection systems can not be effectively developed and
evaluated. The DiffServ working group, as a whole, needs to decide
what the important security issues are (or what specific attacks we
need to defend against). Then, it will be meaningful to discuss the
possible solution to those realistic DiffServ vulnerabilities. Our
objective in this report is to define a model for denial of service
attacks under the DiffServ framework.

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.
