	Title		: Protecting Internet Routing Infrastructure from
                          Outsider CPU Attacks

The mechanism described in this document helps to secure an Internet
Service Provider's router infrastructure from outsider attacks,
including (but not limited to) Distributed denial of service (DDoS)
attacks based on CPU and/or queue exhaustion (e.g., TCP SYN flooding
and flooding of invalid MD5-signed routing protocol packets.) The
presented approach is based on explicitly marking control packets
from trusted sources by different link-layer encapsulation and does
not require any modifications to user data exchange protocols, ICMP,
routing protocols or changes to existing hardware in routers, which
allows it to be deployed quickly throughout the Internet.

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.
