reasons below the strong impact PCE-initiation has from the implementation's perspective (which is somehow linked to the first 2 items). Up to I-D.ietf-pce-stateful-pce, it was all about configuration on PCCs, just allowing PCEs to trigger actions. I-D.ietf-pce-pce-initiated-lsp is a significant change: it enables PCEs to create on PCCs states which are not part of operator-specified PCCs' configuration. As a result, there has already been some commercial implementations at the stage described by the 2nd item. My 2 cents, Julien Oct. 04, 2017 - Jonathan.Hardwick@metaswitch.com: > 1) I'm wondering why this spec is not part of I-D.ietf-pce-stateful-pce as it is also not published yet...? > > Jon> It has been published now. The main reasons were > - it took longer for PCE-initiated LSPs to be accepted into the PCE WG, and the authors did not want to hold up work on the base draft > - I-D.ietf-pce-stateful-pce was a self-contained set of function and it was envisioned that there was a class of device that would not implement the LSP initiation extensions > - I-D.ietf-pce-stateful-pce was already fairly long and complex, and merging them would have been an editing / reviewing headache.

Hi Alvaro

 

Many thanks for your = comments.  I'm picking up this thread and replying as PCE working grou= p chair, as the authors are unavailable.  I am very sorry for the dela= y.

 

For some reason I can= ’t find the original email with your comments in, so I have scraped t= he text from the datatracker and pasted it below.  Please see my propo= sed resolutions inline below, marked with "Jon>"

 

Best regards

Jon=

 

 

Just some minor comments:<= /o:p>

 

(1) Section 3.2

 

   This document defi= nes a new PCEP message, the LSP Initiate Request

   (PCInitiate) messa= ge, which a PCE can send to a PCE to request the

   initiaton or delet= ion of an LSP.

 

s/...PCE can send to a PCE.../.= ..PCE can send to a PCC...

 

Jon> OK.

 

 

(2) Section 5.3: "The sour= ce address MAY be either specified or left up to the PCC decision using the= 0.0.0.0 value."  These seem to be the only two possible options, so s/MAY/MUST.

 

Jon> OK.  So, including the feedback we got = from Adam Roach, the new text is:

 

''The source address MUST either be specified or lef= t for the PCC to choose by setting it to "0.0.0.0" (if the destin= ation is an IPv4 address) or "::" (if the destination is an IPv6 = address).''

 

 

(3) Also from Section 5.3: &quo= t;...the END-POINTS object MAY be included to explicitly convey the destina= tion...For LSPs to be setup by other means, the END-POINTS object MAY be omitted..."

 

You already wrote that "ot= her setup methods are outside the scope".  Also, not including th= e END-POINTS object is not an indication of other types of LSPs, as its use is optional to start with.  Take out the last sentence.

I found a couple of places where SHOULDs seemed at least under-specified, a= nd this one looked important.

I=E2=80=99m having a hard time understanding why a PCE would not compare re= ported PCE-Initiated LSPs with its configuration, which is allowed by the f= irst SHOULD. Does that mean you thought it was important to TRY to synchron= ize, but you=E2=80=99re not curious enough to check whether that worked?
I can imagine reasons why you wouldn't try to fix the LSPs that weren&#= 39;t synchronized, at least not immediately, but you might also give guidan= ce about one or more reasons why you wouldn't try, to help implementers= understand what not doing what the SHOULD means, and make informed choices= for their implementations.

Title : PCEP Extensions for PCE-initiated LSP Setup in a Stateful PCE Model Authors : Edward Crabbe Ina Minei Siva Sivabalan Robert Varga Filename : draft-ietf-pce-pce-initiated-lsp-11.txt Pages : 19 Date : 2017-10-07 Abstract: The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. The extensions for stateful PCE provide active control of Multiprotocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSP) via PCEP, for a model where the PCC delegates control over one or more locally configured LSPs to the PCE. This document describes the creation and deletion of PCE-initiated LSPs under the stateful PCE model.

Title : PCEP Extensions for PCE-initiated LSP Setup in a = Stateful PCE Model Authors : Edward Crabbe Ina Minei Siva Sivabalan Robert Varga Filename : draft-ietf-pce-pce-initiated-lsp-11.txt Pages : 19 Date : 2017-10-07 Abstract: The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. The extensions for stateful PCE provide active control of Multiprotocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSP) via PCEP, for a model where the PCC delegates control over one or more locally configured LSPs to the PCE. This document describes the creation and deletion of PCE-initiated LSPs under the stateful PCE model.

Previous comments follow - I didn't check for these in the new version. In this text, The State Timeout Interval timer ensures that a PCE crash does not result in automatic and immediate disruption for the services using PCE-initiated LSPs. PCE-initiated LSPs are not removed immediately upon PCE failure. Instead, they are cleaned up on the expiration of this timer. This allows for network cleanup without manual intervention. The PCC SHOULD support removal of PCE-initiated LSPs as one of the behaviors applied on expiration of the State Timeout Interval timer. The behavior SHOULD be picked based on local policy, and can result either in LSP removal, or in reverting to operator- defined default parameters. I found myself wondering why “The PCC SHOULD support removal of PCE-initiated LSPs” is a SHOULD, and not a MUST, but if it’s a SHOULD, you might say something about the effects of not supporting this, in order to help implementers make an informed decision about whether to support it. In the same text, I found myself wondering if there were other alternatives to local policy for the last SHOULD, which is, of course, the last stop on the way to asking why this isn’t a MUST … From nobody Tue Oct 10 14:33:06 2017 Return-Path: X-Original-To: pce@ietf.org Delivered-To: pce@ietfa.amsl.com Received: from ietfa.amsl.com (localhost [IPv6:::1]) by ietfa.amsl.com (Postfix) with ESMTP id 3F1A1132E24; Tue, 10 Oct 2017 14:32:59 -0700 (PDT) MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit From: internet-drafts@ietf.org To: Cc: pce@ietf.org X-Test-IDTracker: no X-IETF-IDTracker: 6.63.1 Auto-Submitted: auto-generated Precedence: bulk Message-ID: <150767117918.13575.8934607561739315755@ietfa.amsl.com> Date: Tue, 10 Oct 2017 14:32:59 -0700 Archived-At: Subject: [Pce] I-D Action: draft-ietf-pce-segment-routing-10.txt X-BeenThere: pce@ietf.org X-Mailman-Version: 2.1.22 List-Id: Path Computation Element List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 10 Oct 2017 21:32:59 -0000 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 Extensions for Segment Routing Authors : Siva Sivabalan Clarence Filsfils Jeff Tantsura Wim Henderickx Jon Hardwick Filename : draft-ietf-pce-segment-routing-10.txt Pages : 21 Date : 2017-10-10 Abstract: Segment Routing (SR) enables any head-end node to select any path without relying on a hop-by-hop signaling technique (e.g., LDP or RSVP-TE). It depends only on "segments" that are advertised by Link- State Interior Gateway Protocols (IGPs). A Segment Routed Path can be derived from a variety of mechanisms, including an IGP Shortest Path Tree (SPT), explicit configuration, or a Path Computation Element (PCE). This document specifies extensions to the Path Computation Element Protocol (PCEP) that allow a stateful PCE to compute and initiate Traffic Engineering (TE) paths, as well as a PCC to request a path subject to certain constraint(s) and optimization criteria in SR networks.

This document corrects several errata in the original RFC 6006. Working Group Summary There was no controversy in the working group. The only changes relative to RFC 6006 are straightforward errata corrections. This document progressed rapidly through the working group. Document Quality There is at least one implementation of this protocol, which is why the errata in RFC 6006 were raised, and are now being fixed.

The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pce-pce-initiated-lsp/ Technical Summary The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. The extensions for stateful PCE provide stateful control of Multiprotocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSP) via PCEP, for a model where the PCC delegates control over one or more locally configured LSPs to the PCE. This document describes the creation and deletion of PCE-initiated LSPs under the stateful PCE model. Working Group Summary Given the consensus to consider it, the WG had to update its charter to include that work, which was at the boundary of the former scope. This I-D complements draft-ietf-pce-stateful-pce. Document Quality There are several implementations, including one open source (OpenDaylight). Have a significant number of vendors indicated their plan to implement the specification? Yes, even more than plans. Are there any reviewers that merit special mention as having done a thorough review, e.g., one that resulted in important changes or a conclusion that the document had no substantive issues? Some updates have been triggered by a couple of operators, thanks to some interoperability testing between several implementations. Personnel Who is the Document Shepherd for this document?

RFC 8253 Title: PCEPS: Usage of TLS to Provide a Secure Transport for the Path Computation Element Communication Protocol (PCEP) Author: D. Lopez, O. Gonzalez de Dios, Q. Wu, D. Dhody Status: Standards Track Stream: IETF Date: October 2017 Mailbox: diego.r.lopez@telefonica.com, oscar.gonzalezdedios@telefonica.com, sunseawq@huawei.com, dhruv.ietf@gmail.com Pages: 26 Characters: 56767 Updates: RFC 5440 I-D Tag: draft-ietf-pce-pceps-18.txt URL: https://www.rfc-editor.org/info/rfc8253 DOI: 10.17487/RFC8253 The Path Computation Element Communication Protocol (PCEP) defines the mechanisms for the communication between a Path Computation Client (PCC) and a Path Computation Element (PCE), or among PCEs. This document describes PCEPS -- the usage of Transport Layer Security (TLS) to provide a secure transport for PCEP. The additional security mechanisms are provided by the transport protocol supporting PCEP; therefore, they do not affect the flexibility and extensibility of PCEP. This document updates RFC 5440 in regards to the PCEP initialization phase procedures. This document is a product of the Path Computation Element Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.

This draft is a work item of the Path Computation Element WG of the IETF. Title : Applicability of Path Computation Element (PCE) for Abstraction and Control of TE Networks (ACTN) Authors : Dhruv Dhody Young Lee Daniele Ceccarelli Filename : draft-ietf-pce-applicability-actn-02.txt Pages : 18 Date : 2017-10-28 Abstract: Abstraction and Control of TE Networks (ACTN) refers to the set of virtual network operations needed to orchestrate, control and manage large-scale multi-domain TE networks so as to facilitate network programmability, automation, efficient resource sharing, and end-to- end virtual service aware connectivity and network function virtualization services. The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests.

Authors : Dhruv Dhody Young Lee Daniele Ceccarelli Jongyoon Shin Daniel King Oscar Gonzalez de Dios Filename : draft-ietf-pce-stateful-hpce-02.txt Pages : 19 Date : 2017-10-28 Abstract: A Stateful Path Computation Element (PCE) maintains information on the current network state, including: computed Label Switched Path (LSPs), reserved resources within the network, and pending path computation requests. This information may then be considered when computing new traffic engineered LSPs, and for associated and dependent LSPs, received from Path Computation Clients (PCCs). The Hierarchical Path Computation Element (H-PCE) architecture, provides an architecture to allow the optimum sequence of inter-connected domains to be selected, and network policy to be applied if applicable, via the use of a hierarchical relationship between PCEs. Combining the capabilities of Stateful PCE and the Hierarchical PCE would be advantageous. This document describes general considerations and use cases for the deployment of Stateful PCE(s) using the Hierarchical PCE architecture.

This draft is a work item of the Path Computation Element WG of the IETF. Title : Conveying path setup type in PCEP messages Authors : Siva Sivabalan Jeff Tantsura Ina Minei Robert Varga Jon Hardwick Filename : draft-ietf-pce-lsp-setup-type-05.txt Pages : 8 Date : 2017-10-29 Abstract: A Path Computation Element can compute traffic engineering paths (TE paths) through a network that are subject to various constraints. Currently, TE paths are label switched paths (LSPs) which are set up using the RSVP-TE signaling protocol. However, other TE path setup methods are possible within the PCE architecture. This document proposes an extension to PCEP to allow support for different path setup methods over a given PCEP session.
