Abstract

   The Optical Interworking Forum (OIF) has defined extensions to the
   Label Distribution Protocol (LDP) and the Resource ReSerVation
   Protocol (RSVP) for optical User Network Interface (UNI) signaling.
   These extensions consist of a set of new data objects and error
   codes.  This document describes these extensions.

1. Introduction

   The OIF UNI signaling specification is described in [8].  This
   specification utilizes IETF protocol standards as well as IETF work
   in progress.  Specifically, the following IETF specifications are
   used:

   o  Label distribution protocol (LDP) [6]
   o  Resource reservation protocol (RSVP) [5]
   o  GMPLS signaling and GMPLS extensions for SONET/SDH [4]
   o  GMPLS RSVP-TE and CR-LDP extensions [2, 3]

   The aim of the OIF UNI specification is the maximal re-use of IETF
   protocol definitions.  A few extensions to IETF protocols, however,
   have been defined to serve UNI-specific needs.  These extensions are
   described in this document.
