The hierachical Path Computation Element (PCE) architecture defined 
in [PCE-HIERARCHY-FWK] allows the optimum sequence of domains to be
selected, 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 in [PCE-HIERARCHY-FWK].
