               Requirements for GMPLS applications of PCE
                  draft-ietf-pce-gmpls-aps-req-07.txt

Abstract

   The initial effort of the PCE WG is specifically focused on MPLS
   (Multi-protocol label switching).  As a next step, this draft
   describes functional requirements for GMPLS (Generalized MPLS)
   application of PCE (Path computation element).

1.  Introduction

   The initial effort of the PCE WG is focused on solving the path
   computation problem within a domain or over different domains in MPLS
   networks.  As the same case with MPLS, service providers (SPs) have
   also come up with requirements for path computation in GMPLS-
   controlled networks such as wavelength, TDM-based or Ethernet-based
   networks as well.

   [RFC4655] and [RFC4657] discuss the framework and requirements for
   PCE on both packet MPLS networks and GMPLS-controlled networks.  This
   document complements these RFCs by providing some considerations of
   GMPLS applications in the intra-domain and inter-domain networking
   environments and indicating a set of requirements for the extended
   definition of PCE-related protocols.

   Note that the requirements for inter-layer traffic engineering
