Title : Distribution of Link-State and Traffic Engineering Information Using BGP
Author : Ketan Talaulikar
Filename : draft-ietf-idr-rfc7752bis-13.txt
Pages : 70

Abstract:
In many environments, a component external to a network is called
upon to perform computations based on the network topology and the
current state of the connections within the network, including
Traffic Engineering (TE) information. This is information typically
distributed by IGP routing protocols within the network.

This document describes a mechanism by which link-state and TE
information can be collected from networks and shared with external
components using the BGP routing protocol. This is achieved using a
new BGP Network Layer Reachability Information (NLRI) encoding
format. The mechanism applies to physical and virtual (e.g., tunnel)
IGP links. The mechanism described is subject to policy control.

Applications of this technique include Application-Layer Traffic
Optimization (ALTO) servers and Path Computation Elements (PCEs).

This document obsoletes RFC7752 by completely replacing that
document. It makes some small changes and clarifications to the
previous specification. This document also obsoletes RFC9029 by
incorporating the updates that it made to RFC7752.
