Title : Extensions to Path Computation Element Communication Protocol (PCEP) for Hierarchical Path Computation Elements (PCE)
Author(s) : F. Zhang, et al.
Filename : draft-zhang-pce-hierarchy-extensions-00.txt
Pages : 14

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].
