A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG of the IETF. Title : PCEP Extension for WSON Routing and Wavelength Assignment Authors : Young Lee Ramon Casellas Filename: draft-ietf-pce-wson-rwa-ext-09.txt Pages : 25 Date: 2018-11-04 Abstract: This document provides the Path Computation Element communication Protocol (PCEP) extensions for the support of Routing and Wavelength Assignment (RWA) in Wavelength Switched Optical Networks (WSON). Lightpath provisioning in WSONs requires a routing and wavelength assignment (RWA) process. From a path computation perspective, wavelength assignment is the process of determining which wavelength can be used on each hop of a path and forms an additional routing constraint to optical light path computation.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG of the IETF. Title : PCEP Procedures and Protocol Extensions for Using PCE as a Central Controller (PCECC) of LSPs Authors : Quintin Zhao Zhenbin Li Dhruv Dhody Satish Karunanithi Adrian Farrel Chao Zhou Filename: draft-ietf-pce-pcep-extension-for-pce-controller-00.txt Pages : 30 Date: 2018-11-04 Abstract: The Path Computation Element (PCE) is a core component of Software- Defined Networking (SDN) systems. It can compute optimal paths for traffic across a network and can also update the paths to reflect changes in the network or traffic demands. PCE was developed to derive paths for MPLS Label Switched Paths (LSPs), which are supplied to the head end of the LSP using the Path Computation Element Communication Protocol (PCEP). But SDN has a broader applicability than signaled (G)MPLS traffic-engineered (TE) networks, and the PCE may be used to determine paths in a range of use cases. PCEP has been proposed as a control protocol for use in these environments to allow the PCE to be fully enabled as a central controller. A PCE-based central controller (PCECC) can simplify the processing of a distributed control plane by blending it with elements of SDN and without necessarily completely replacing it. Thus, the LSP can be calculated/setup/initiated and the label forwarding entries can also be downloaded through a centralized PCE server to each network devices along the path while leveraging the existing PCE technologies as much as possible. This document specifies the procedures and PCEP protocol extensions for using the PCE as the central controller.

A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG 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 R. Casellas Daniel King Filename: draft-ietf-pce-hierarchy-extensions-06.txt Pages : 30 Date: 2018-11-04 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.

Re: [Pce] New Version Notification for draft-ietf-pce-hierarchy-extensions-06.txt
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.

[Pce] FW: VN Association @ PCE
Hi Jon, The following is the text agreed upon between Igor and Dhruv and myself. --- we will update the draft with this added text in the revision. NEW: VN association can be generally applicable to bundle TE tunnel sets where a VN member within a VN corresponds to a TE tunnel Thanks.

Just like a group of LSPs in a mesh. Our resolution is to add text: "VN association can be generally applicable to bundle TE tunnel sets where a VN member within a VN corresponds to a TE tunnel."
