Abstract
This document is a companion to the Generalized Multi-Protocol Label
Switching (GMPLS) signaling documents. It describes the technology-
specific information needed to extend GMPLS signaling to control
Optical Transport Networks (OTN); it also includes the so-called
pre-OTN developments.

1. Introduction
Generalized Multi-Protocol Label Switching (GMPLS) [RFC3945] extends
MPLS from supporting Packet Switching Capable (PSC) interfaces and
switching to include support of four new classes of interfaces and
switching: Layer-2 Switching (L2SC), Time-Division Multiplex (TDM),
Lambda Switch (LSC), and Fiber-Switch (FSC) Capable. A functional
description of the extensions to MPLS signaling that are needed to
support these new classes of interfaces and switching is provided in
[RFC3471]. [RFC3473] describes the RSVP-TE-specific formats and
mechanisms needed to support all four classes of interfaces.
This document presents the technology details that are specific to
G.709 Optical Transport Networks (OTN) as specified in the ITU-T
G.709 recommendation [ITUT-G709] (and referenced documents),
including pre-OTN developments. Per [RFC3471], G.709 technology-
specific parameters are carried through the signaling protocol in
dedicated traffic parameter objects.
The G.709 traffic parameters defined hereafter (see Section 3.2) MUST
be used when the label is encoded as defined in this document.
Moreover, the label MUST be encoded as defined in Section 4 when
these G.709 traffic parameters are used.
In the context of this memo, by pre-OTN developments, one refers to
Optical Channel, Digital Wrapper and Forward Error Correction (FEC)
