This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCE Communication Protocol (PCECP) specific requirements for Inter-Area (G)MPLS Traffic Engineering Author(s) : J. Le Roux Filename : draft-ietf-pce-pcecp-interarea-reqs-00.txt Pages : 19 Date : 2005-12-1 For scalability purposes a network may comprise multiple IGP areas. An inter-area TE-LSP is an LSP that transits through at least two IGP areas. In a multi-area network, topology visibility remains local to a given area, and a head-end LSR cannot compute alone an inter-area shortest constrained path. One key application of the Path Computation Element (PCE) architecture is the computation of inter- area TE-LSP paths. In this context, this document lists a detailed set of PCE Communication Protocol (PCECP) specific requirements for support of inter-area TE-LSP path computation. It complements generic requirements for a PCE Communication Protocol.

Filename : draft-ietf-pce-architecture-03.txt Pages : 37 Date : 2005-12-9 Constraint-based path computation is a fundamental building block for traffic engineering systems such as Multiprotocol Label Switching (MPLS) and Generalized Multiprotocol Label Switching (GMPLS) networks. Path computation in large, multi-domain, multi-region or multi-layer networks is complex and may require special computational components and cooperation between the different network domains. This document specifies the architecture for a Path Computation Element (PCE)-based model to address this problem space. This document does not attempt to provide a detailed description of all the architectural components, but rather it describes a set of building blocks for the PCE architecture from which solutions may be constructed.

Hi, Jean-Louis
 
 I have some comment on the draft draft-ietf-pce-pcecp-interarea-reqs-00.txt
 
 In section 7.11.1, In case of network failure, jittering will be used to avoid
simultaneous requests sent to one PCE. Could more consideration be given here to
the preemptment, becouse the jittering timeout is stochastic, some lower request
may be served before a higher request and the path may be calculated differently.
which may increase the probability of a preemptment.
 
 I have always been thinking a question: if a PCC will not perform the CSPF 
computation, why does it still maintain the TEDB any longer? which may consume
a lot of memory and CPU of a LSR.This question dost not aid at this draft.
 
 In inter-area environment,sometimes, a PCC may wish to get as many paths as possible,
for all kinds of purpose,so could the PCC send the request to more than one PCEs?

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCE Communication Protocol Generic Requirements Author(s) : J. Le Roux, J. Ash Filename : draft-ietf-pce-comm-protocol-gen-reqs-03.txt Pages : 22 Date : 2005-12-28 The PCE model is described in the "PCE Architecture" document and facilitates path computation requests from Path Computation Clients (PCCs) to Path Computation Elements (PCEs). This document specifies generic requirements for a communication protocol between PCCs and PCEs, and also between PCEs where cooperation between PCEs is desirable. Subsequent documents will specify application-specific requirements for the PCE communication protocol.

Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-ietf-pce-comm-protocol-gen-reqs-03.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-pce-comm-protocol-gen-reqs-03.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <2005-12-28094245.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-ietf-pce-comm-protocol-gen-reqs-03.txt --OtherAccess Content-Type: Message/External-body; name="draft-ietf-pce-comm-protocol-gen-reqs-03.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <2005-12-28094245.I-D@ietf.org> --OtherAccess-- --NextPart Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Pce mailing list Pce@lists.ietf.org https://www1.ietf.org/mailman/listinfo/pce --NextPart-- From pce-bounces@lists.ietf.org Wed Dec 28 12:19:02 2005 Received: from localhost.cnri.reston.va.us ([127.0.0.1] helo=megatron.ietf.org) by megatron.ietf.org with esmtp (Exim 4.32) id 1Erex4-0008Tt-8c; Wed, 28 Dec 2005 12:19:02 -0500 Received: from odin.ietf.org ([132.151.1.176] helo=ietf.org) by megatron.ietf.org with esmtp (Exim 4.32) id 1Erex2-0008Tj-Ak for pce@megatron.ietf.org; Wed, 28 Dec 2005 12:19:00 -0500 Received: from ietf-mx.ietf.org (ietf-mx [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id MAA12732 for ; Wed, 28 Dec 2005 12:17:49 -0500 (EST) Received: from mail126.messagelabs.com ([216.82.254.83]) by ietf-mx.ietf.org with smtp (Exim 4.43) id 1Erf13-0002d6-EB for pce@ietf.org; Wed, 28 Dec 2005 12:23:13 -0500 X-VirusChecked: Checked X-Env-Sender: gash@att.com X-Msg-Ref: server-6.tower-126.messagelabs.com!1135790309!10888752!5 X-StarScan-Version: 5.5.9.1; banners=-,-,- X-Originating-IP: [134.24.146.4] Received: (qmail 20490 invoked from network); 28 Dec 2005 17:18:45 -0000 Received: from unknown (HELO attrh3i.attrh.att.com) (134.24.146.4) by server-6.tower-126.messagelabs.com with SMTP; 28 Dec 2005 17:18:45 -0000 Received: from kcclust06evs1.ugd.att.com (135.38.164.88) by attrh3i.attrh.att.com (7.2.052) id 43AED14A000382C3 for pce@ietf.org; Wed, 28 Dec 2005 12:18:45 -0500 X-MimeOLE: Produced By Microsoft Exchange V6.5.7226.0 Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Date: Wed, 28 Dec 2005 11:18:45 -0600 Message-ID: <9473683187ADC049A855ED2DA739ABCA09FA9842@KCCLUST06EVS1.ugd.att.com> Thread-Topic: I-D ACTION:draft-ietf-pce-comm-protocol-gen-reqs-03.txt Thread-Index: AcYLyg7r9fYT60FcSF65LhClU/gvggAB5yJg From: "Ash, Gerald R \(Jerry\), ALABS" To: X-Spam-Score: 0.0 (/) X-Scan-Signature: 7aafa0432175920a4b3e118e16c5cb64 Content-Transfer-Encoding: quoted-printable Cc: Subject: [Pce] RE: I-D ACTION:draft-ietf-pce-comm-protocol-gen-reqs-03.txt X-BeenThere: pce@lists.ietf.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Path Computation Element List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: pce-bounces@lists.ietf.org Errors-To: pce-bounces@lists.ietf.org Hi All, Please review and comment on the updated version of the PCE communications protocol (PCECP) generic requirements I-D http://www.ietf.org/internet-drafts/draft-ietf-pce-comm-protocol-gen-req s-03.txt. Per our agreements at IETF-64 (see JL's slide at http://www3.ietf.org/proceedings/05nov/slides/pce-11/sld7.htm), the referenced requirements in the inter-area PCECP requirements draft have been moved into the generic PCECP requirements draft. In particular, - Section 6.1.17 'Objective Functions Supported' was added - Section 6.3.4 'LSP Rerouting & Reoptimization' was updated Our objective is to start a WG last call soon. We look forward to your review and comments.
