I-D Action: draft-ietf-pce-inter-layer-ext-06.txt


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 the Path Computation Element communication Protocol (PCEP) for Inter-Layer MPLS
and GMPLS Traffic Engineering

   The Path Computation Element (PCE) provides path computation
   functions in support of traffic engineering in Multiprotocol Label
   Switching (MPLS) and Generalized MPLS (GMPLS) networks.

   MPLS and GMPLS networks may be constructed from layered service
   networks. It is advantageous for overall network efficiency to
   provide end-to-end traffic engineering across multiple network layers
   through a process called inter-layer traffic engineering. PCE is a
   candidate solution for such requirements.

   The PCE communication Protocol (PCEP) is designed as a communication
   protocol between Path Computation Clients (PCCs) and PCEs. This
   document presents PCEP extensions for inter-layer traffic engineering.

Re: I-D Action: draft-ietf-pce-inter-layer-ext-06.txt

Hi all,

We have updated this draft to clarify the dependency between SWITCH-LAYER object and INTER-LAYER object.

Please see the changes and give your comments.




Thanks

   The initial effort of PCE WG is specifically focused on MPLS (Multi-
   protocol label switching). As a next step, this draft describes
   functional requirements for GMPLS (Generalized MPLS) application of
   PCE (Path computation element).

Re: I-D Action: draft-ietf-pce-gmpls-aps-req-05.txt

Hi all,

I just submitted a new version of this draft to make it alive.

We just refined some editorial wording and re-organized the references, ie., no new requirements have
been introduced.

Please have a look and see if it is ready for WG LC.




Thanks

   The Path Computation Element (PCE) may be used for computing services
   that traverse multi-area and multi-AS Multiprotocol Label Switching
   (MPLS) and Generalized MPLS (GMPLS) Traffic Engineered (TE) networks.

   This document examines the applicability of the PCE architecture,
   protocols, and protocol extensions for computing multi-area and
   multi-AS paths in MPLS and GMPLS networks.

New Version of draft-ietf-pce-inter-area-as-applicability (02)

Hi All, 

Please note we published a new version of our draft. So, what has been
updated for draft-ietf-pce-inter-area-as-applicability-02?

- Completed the document sections. A few "bits" of new text added.
- Reordering of Sections to help with readability.
- Additional text and references to help readers with background PCE
reading.

Although we have some operators contributing it would be good to have more
operator/provider feedback. Specifically:

1. Did we miss an inter-area/inter-as use case, feature or function?

2. Does the document and specific sections make sense? The intention as to
provide an overview of PCE technology and its applicability to inter-as AND
inter-area path computation. Have we been successful?

3. Are we missing any PCE technology, mechanisms, protocol extensions? So
far I think we have touched on the following technologies in the document:

[RFC3209] and [RFC3473] - RSVP-TE Primers
[RFC4655] - PCE Architecture
[RFC4726] - Inter-Domain MPLS-TE
[RFC5088] and [RFC5089] - IGP PCE Discovery
[RFC5152] - Per-Domain
[RFC5440] - PCEP
[RFC5441] - BRPC
[RFC5520] - Path-Key

New version of stateful PCE draft & request for adoption

Dear PCEers,

We've submitted a new version of our stateful PCE draft.  This version incorporates the suggestions made in Taipei and on the mailing list (many thanks to all of the reviewers.)  



When we talked about this work in Taipei and discussed WG adoption there were several small issues raised that we committed to fixing before requesting WG adoption.  This revision resolves all of the points that were raised.  At this point we believe there is sufficient interest from a broad enough group of vendors and customers to make it worth being developed further within the WG.

We'd like to request that draft-crabbe-pce-stateful-pce be considered for adoption as a PCE WG document.  

best,

  -ed

A new version of I-D, draft-crabbe-pce-stateful-pce-02.txt has been successfully submitted by Jan Medved and posted to the IETF repository.

Filename:        draft-crabbe-pce-stateful-pce
Revision:        02
Title:           PCEP Extensions for Stateful PCE
Creation date:   2012-01-22
WG ID:           Individual Submission
Number of pages: 51

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.

  Although PCEP explicitly makes no assumptions regarding the
  information available to the PCE, it also makes no provisions for
  synchronization or PCE control of timing and sequence of path
  computations within and across PCEP sessions.  This document
  describes a set of extensions to PCEP to enable this functionality,
  providing stateful control of Multiprotocol Label Switching (MPLS)
  Traffic Engineering Label Switched Paths (TE LSP) via PCEP.
