A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element Working Group of the IETF. Title : Extensions to Path Computation Element Communication Protocol (PCEP) for Hierarchical Path Computation Elements (PCE) Authors : Fatai Zhang Quintin Zhao Oscar Gonzalez de Dios Ramon Casellas Daniel King Filename : draft-ietf-pce-hierarchy-extensions-02.txt Pages : 19 Date : 2015-01-27 Abstract: The Hierarchical Path Computation Element (H-PCE) architecture, 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 Hierarchical PCE procedures which are described in the aforementioned document. These extensions are experimental and published for examination, discussion, implementation, and evaluation.
