A New Internet-Draft is available from the on-line Internet-Drafts
directories.
Title : Dissemination of flow specification rules
Author(s) : P. Marques, et al.
Filename : draft-marques-idr-flow-spec-04.txt
Pages : 25
Date : 2007-7-8
This document defines a new BGP NLRI encoding format that can be used
to distribute traffic flow specifications. This allows the routing
system to propagate information regarding more-specific components of
the traffic aggregate defined by an IP destination prefix.
Additionally it defines two applications of that encoding format.
One that can be used to automate inter-domain coordination of traffic
filtering, such as what is required in order to mitigate
(distributed) denial of service attacks. And a second application to
traffic filtering in the context of a BGP/MPLS VPN service.
The information is carried via the Border Gateway Protocol (BGP),
thereby reusing protocol algorithms, operational experience and
administrative processes such as inter-provider peering agreements.

In the body type:

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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
