Greetings PCE'rs, Please find a new version of draft-ietf-pce-hierarchy-extensions (version 06). Thanks to Adrian Farrel for his recent and thorough review, it helped the authors polish the I-D.
Revisions to the new version of the I-D include: - Updated Abstract - Updated Introduction - Updated Security text - Added RFC7399 (Unanswered questions of the PCE) text and reference to Introduction Scope - Consistency of "Objective Functions" text - Revised H-PCE-CAPABILITY TLV format and behavior - Cleaned up Section 3.3.1 OF Codes - Consistency of text and readability updates - Added IANA allocation policy to IANA Section - Implementation Status moved to an Appendix with statement that this will be removed before publication There is one material change to protocol solution in the I-D. It is proposed that the H-PCE-CAPABILITY TLV should now use one flag (P-bit), instead of two. If set, will signal that the child PCE wishes to use the peer PCE as a parent PCE: https://tools.ietf.org/html/draft-ietf-pce-hierarchy-extensions-06#page-8 The authors will follow-up with Adrian, via the PCE list, and respond to his specific comments in a separate email.

Name: draft-ietf-pce-hierarchy-extensions Revision: 06 Title: Extensions to Path Computation Element Communication Protocol (PCEP) for Hierarchical Path Computation Elements (PCE) Document date: 2018-11-05 Group: pce Pages: 30 URL: https://www.ietf.org/internet-drafts/draft-ietf-pce-hierarchy-extensions-06.txt Status: https://datatracker.ietf.org/doc/draft-ietf-pce-hierarchy-extensions/ Htmlized: https://tools.ietf.org/html/draft-ietf-pce-hierarchy-extensions-06 Htmlized: https://datatracker.ietf.org/doc/html/draft-ietf-pce-hierarchy-extensions Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-pce-hierarchy-extensions-06 Abstract: The Hierarchical Path Computation Element (H-PCE) architecture is defined in RFC 6805. It provides a mechanism to derive an optimum end-to-end path in a multi-domain environment by using a hierarchical relationship between domains to select the optimum sequence of domains and optimum paths across those domains. This document defines extensions to the Path Computation Element Protocol (PCEP) to support Hierarchical PCE procedures. _______________________________________________ Pce mailing list Pce@ietf.org https://www.ietf.org/mailman/listinfo/pce
