Abstract

   Generalized Multiprotocol Label Switching (GMPLS) has been developed
   by the IETF to facilitate the establishment of Label Switched Paths
   (LSPs) in a variety of data plane technologies and across several
   architectural models.  The ITU-T has specified an architecture for
   the control of Automatically Switched Optical Networks (ASON).

   This document provides a lexicography for the interpretation of GMPLS
   terminology within the context of the ASON architecture.

   It is important to note that GMPLS is applicable in a wider set of
   contexts than just ASON.  The definitions presented in this document
   do not provide exclusive or complete interpretations of GMPLS
   concepts.  This document simply allows the GMPLS terms to be applied
   within the ASON context.

1.  Introduction

   Generalized Multiprotocol Label Switching (GMPLS) has been developed
   by the IETF to facilitate the establishment of Label Switched Paths
   (LSPs) in a variety of data plane technologies such as Packet
   Switching Capable (PSC), Layer Two Switching Capable (L2SC), Time
   Division Multiplexing (TDM), Lambda Switching Capable (LSC), and
   Fiber Switching Capable (FSC).

   The ITU-T has specified an architecture for the control of
   Automatically Switched Optical Networks (ASON).  This architecture
   forms the basis of many Recommendations within the ITU-T.

   Because the GMPLS and ASON architectures were developed by different
   people in different standards bodies, and because the architectures
   have very different historic backgrounds (the Internet, and transport
   networks respectively), the terminology used is different.

   This document provides a lexicography for the interpretation of GMPLS
   terminology within the context of the ASON architecture.  This allows
   GMPLS documents to be generally understood by those familiar with
