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.

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].
