RSVP ASSOCIATION Object Extensions
Abstract
The RSVP ASSOCIATION object was defined in the context of GMPLS-
controlled Label Switched Paths (LSPs). In this context, the object
is used to associate recovery LSPs with the LSP they are protecting.
This object also has broader applicability as a mechanism to
associate RSVP state. This document defines how the ASSOCIATION
object can be more generally applied. This document also defines
Extended ASSOCIATION objects that, in particular, can be used in the
context of the MPLS Transport Profile (MPLS-TP). This document
updates RFC 2205, RFC 3209, and RFC 3473. It also generalizes the
definition of the Association ID field defined in RFC 4872.

RFC 6780 RSVP Extensions October 2012
1. Introduction
End-to-end and segment recovery are defined for GMPLS-controlled
Label Switched Paths (LSPs) in [RFC4872] and [RFC4873], respectively.
Both definitions use the ASSOCIATION object to associate recovery
LSPs with the LSP they are protecting. Additional narrative on how
such associations are to be identified is provided in [RFC6689].
