Dissemination of Flow Specification Rules
RFC 5575, “Dissemination of Flow Specification Rules”, is a Proposed Standard document published in August 2009 by P. Marques, N. Sheth, R. Raszuk, B. Greene, J. Mauch, D. McPherson. It has since been updated by RFC 7674. It has been obsoleted by RFC 8955 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
This document defines a new Border Gateway Protocol Network Layer Reachability Information (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 provide traffic filtering in the context of a BGP/MPLS VPN service.
The information is carried via the BGP, thereby reusing protocol algorithms, operational experience, and administrative processes such as inter-provider peering agreements. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
