Flexible Algorithm is a solution that allows some routing protocols
(e.g., OSPF and IS-IS) to compute paths over a network based on
user-defined (and hence, flexible) constraints and metrics. The
computation is performed by routers participating in the specific
network in a distributed manner using a Flexible Algorithm Definition
(FAD). This definition is provisioned on one or more routers and
propagated through the network by OSPF and IS-IS flooding.
Border Gateway Protocol - Link State (BGP-LS) enables the collection
of various topology information from the network. This document
defines extensions to the BGP-LS address family to advertise the FAD
as a part of the topology information from the network.
This document is a product of the Inter-Domain Routing Working Group of the
IETF.
This is now a Proposed Standard.
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 Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
