The hierarchical Path Computation Element (PCE) architecture, defined
in the companion framework document [I-D.ietf-pce-hierarchy-fwk],
allows the selection of an optimum domain sequence and the optimum
end-to-end path, to be derived through the use of a hierarchical
relationship between domains.
This document defines the Path Computation Element Protocol (PCEP)
extensions for the purpose of implementing hierarchical PCE
procedures which are described the aforementioned document.
