                          LSP Attribute in ERO
               draft-margaria-ccamp-lsp-attribute-ero-02

Abstract

   LSP attributes can be specified or recorded for whole path, but they
   cannot be targeted to a specific hop.  This document proposes
   alternative ways to extend the semantic for RSVP ERO object to target
   LSP attributes to a specific hop.

1.  Introduction

   Generalized MPLS (GMPLS) Traffic Engineering (TE) Label Switched
   Paths (LSPs) can be route-constrained by making use of the Explicit
   Route (ERO) object and related sub-objects as defined in [RFC3209],
   [RFC3473], [RFC3477], [RFC4873], [RFC4874], [RFC5520] and [RFC5553].
   This document proposes mechanisms to target LSP attributes at a
   specific hop.  This document presents several solutions for
   discussion, final document will contains only one document after WG
   consensus.
