From: The IESG <email@example.com> To: IETF-Announce <firstname.lastname@example.org> Cc: Internet Architecture Board <email@example.com>, RFC Editor <firstname.lastname@example.org>, idr mailing list <email@example.com>, idr chair <firstname.lastname@example.org> Subject: Protocol Action: 'Dissemination of flow specification rules' to Proposed Standard The IESG has approved the following document: - 'Dissemination of flow specification rules ' <draft-ietf-idr-flow-spec-09.txt> as a Proposed Standard This document is the product of the Inter-Domain Routing Working Group. The IESG contact persons are Adrian Farrel and Ross Callon. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-idr-flow-spec-09.txt
Technical Summary 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. Working Group Summary Consensus on the technology was not an issue. There was an IPR disclosure that occurred after WG LC. Document Quality There are multiple, interoperable implementations. There were no LC comments during WG LC although the technology and draft have been known, discussed and available for many years.
