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.
