A new Request for Comments is now available in online RFC libraries. RFC 5575 Title: Dissemination of Flow Specification Rules Author: P. Marques, N. Sheth, R. Raszuk, B. Greene, J. Mauch, D. McPherson Status: Standards Track Date: August 2009 Mailbox: roque@cisco.com, nsheth@juniper.net, raszuk@cisco.com, bgreene@juniper.net, jmauch@us.ntt.net, danny@arbor.net Pages: 22 Characters: 46473 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-idr-flow-spec-09.txt URL: http://www.rfc-editor.org/rfc/rfc5575.txt 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] This document is a product of the Inter-Domain Routing Working Group of the IETF. This is now a Proposed Standard Protocol. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
