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.

2. LDP Extensions for UNI Signaling

   The LDP extensions for UNI signaling consist of new TLVs that capture
   UNI-specific parameters and new UNI-specific status codes.  The new
   TLVs are Source ID (3 TLVs), Destination ID (3 TLVs), Egress Label,
   Local Connection ID, Diversity, Contract ID, and UNI Service Level
   [8].  These are described below.  The new status codes are assigned
   from the private use space of LDP codes, as described in [8].  The
   UNI specification [8] also defines two new LDP messages, Status
   Enquiry and Status Response.  These messages have been obsoleted and
   hence no code points are requested in this document for them.

2.1  Source ID TLVs

   Three TLVs have been defined to encode the Source ID. The content and
   usage of these TLVs are described in [8].
