The Hierarchical Path Computation Element (H-PCE) architecture (RFC 6805), provides a mechanism to allow 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 necessary Hierarchical PCE procedures and protocol extensions.
