Constraint-based path computation is a fundamental building block for
traffic engineering systems such as Multiprotocol Label Switching
(MPLS) and Generalized Multiprotocol Label Switching (GMPLS)
networks.  Path computation in large, multi-domain, multi-region, or
multi-layer networks is complex and may require special
computational components and cooperation between the different
network domains.

This document specifies the architecture for a Path Computation
Element (PCE)-based model to address this problem space.  This
document does not attempt to provide a detailed description of all
the architectural components, but rather it describes a set of
building blocks for the PCE architecture from which solutions may be
constructed.  This memo provides information for the Internet community.

This document is a product of the Path Computation Element
Working Group of the IETF.
