Abstract

The Link Management Protocol (LMP) is defined to manage traffic engineering (TE) links. In its present form, LMP focuses on peer nodes, i.e., nodes that peer in signaling and/or routing. This document proposes extensions to LMP to allow it to be used between a peer node and an adjacent optical line system (OLS). These extensions are intended to satisfy the "Optical Link Interface Requirements" described in a companion document.

Abstract

   The Link Management Protocol (LMP) is defined to manage traffic
   engineering (TE) links.  In its present form, LMP focuses on peer
   nodes, i.e., nodes that peer in signaling and/or routing.  This
   document proposes extensions to LMP to allow it to be used between a
   peer node and an adjacent optical line system (OLS).  These
   extensions are intended to satisfy the "Optical Link Interface
   Requirements" described in a companion document.

1.  Introduction

   Networks are being developed with routers, switches, optical cross-
   connects (OXCs), dense wavelength division multiplexing (DWDM)
   optical line systems (OLSes), and add-drop multiplexors (ADMs) that
   use a common control plane (e.g., Generalized MPLS (GMPLS)) to
   dynamically provision resources and to provide network survivability
   using protection and restoration techniques.

   The Link Management Protocol (LMP) is being developed as part of the
   GMPLS protocol suite to manage traffic engineering (TE) links
   [RFC4204].  In its present form, LMP focuses on peer nodes, i.e.,
   nodes that peer in signaling and/or routing (e.g., OXC-to-OXC, as
   illustrated in Figure 1).  In this document, extensions to LMP are
   proposed to allow it to be used between a peer node and an adjacent
   optical line system (OLS).  These extensions are intended to satisfy
