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.
