I-D Action:draft-ietf-pce-manageability-requirements-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           : Inclusion of Manageability Sections in PCE Working Group Drafts
	Author(s)       : A. Farrel
	Filename        : draft-ietf-pce-manageability-requirements-06.txt
	Pages           : 13
	Date            : 2009-01-04

It has often been the case that manageability considerations have
been retrofitted to protocols after they have been specified,
standardized, implemented, or deployed. This is sub-optimal.

Similarly, new protocols or protocol extensions are frequently
designed without due consideration of manageability requirements.

This document specifies the recommendation for all new
Internet-Drafts in the PCE Working Group to include a
"Manageability Considerations" section, and gives guidance on what
that section should contain.

Working Group Last Call Complete:draft-ietf-pce-global-concurrent-optimization-05.txt

Hi,

We allowed a little extra time over Christmas in case someone was sitting on 
comments, but it looks like we are done with no comments.

If the authors would care to resubmit the I-D with updated IPR boilerplate, 
the chairs will pass it on to the AD.

Thanks,
Adrian

I-D ACTION:draft-ietf-pce-inter-layer-req-09.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		: PCC-PCE Communication and PCE Discovery Requirements for Inter-Layer Traffic Engineering
	Author(s)	: E. Oki, J. Le Roux, K. Kumaki, A. Farrel, T. Takeda
	Filename	: draft-ietf-pce-inter-layer-req-09.txt
	Pages		: 13
	Date		: 2009-1-5
	
The Path Computation Element (PCE) provides functions of path 
   computation in support of traffic engineering in Multi-Protocol Label 
   Switching (MPLS) and Generalized MPLS (GMPLS) networks. 

   MPLS and GMPLS networks may be constructed from layered client/server 
   networks. It is advantageous for overall network efficiency to 
   provide end-to-end traffic engineering across multiple network layers. 
   PCE is a candidate solution for such requirements. 

   Generic requirements for a communication protocol between Path 
   Computation Clients (PCCs) and PCEs are presented in "PCE 
   Communication Protocol Generic Requirements". Generic requirements 
   for PCE discovery protocol are presented in "Requirements for Path 
   Computation Element (PCE) Discovery". 

 
   This document complements the generic requirements and presents 
   detailed sets of PCC-PCE communication protocol requirements and PCE 
   discovery protocol requirements for inter-layer traffic engineering.

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
	Author(s)	: E. Oki, J. Le Roux, A. Farrel

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.

I-D Action:draft-ietf-pce-inter-layer-frwk-08.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           : Framework for PCE-Based Inter-Layer MPLS and GMPLS Traffic Engineering
	Author(s)       : E. Oki, et al.
	Filename        : draft-ietf-pce-inter-layer-frwk-08.txt
	Pages           : 30
	Date            : 2009-01-06

A network may comprise multiple layers. It is important to globally
optimize network resource utilization, taking into account all
layers, rather than optimizing resource utilization at each layer
independently. This allows better network efficiency to be achieved
through a process that we call inter-layer traffic engineering. The
Path Computation Element (PCE) can be a powerful tool to achieve
inter-layer traffic engineering.

This document describes a framework for applying the PCE-based
architecture to inter-layer Multiprotocol Label Switching (MPLS) and
Generalized MPLS (GMPLS) traffic engineering. It provides
suggestions for the deployment of PCE in support of multi-layer
networks. This document also describes network models where PCE
performs inter-layer traffic engineering, and the relationship
between PCE and a functional component called the Virtual Network
Topology Manager (VNTM).

Re: I-D Action:draft-ietf-pce-inter-layer-frwk-09.txt

Hi,

Fixed some formatting
Put in the new IPR boilerplate
Added a null IANA section
Fixed several of the sequences to renumber the action steps.

The authors believe this I-D is now ready for last call.

Thanks,
Adrian

I-D Action:draft-ietf-pce-global-concurrent-optimization-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           : Path Computation Element Communication Protocol (PCECP) Requirements and Protocol Extensions
In Support of Global Concurrent Optimization
	Author(s)       : Y. Lee, et al.
	Filename        : draft-ietf-pce-global-concurrent-optimization-06.txt
	Pages           : 31
	Date            : 2009-01-05

The Path Computation Element (PCE) is a network component,
application, or node that is capable of performing path computations
at the request of Path Computation Clients (PCCs).  The PCE is
applied in Multiprotocol Label Switching Traffic Engineering
(MPLS-TE) networks and in Generalized MPLS (GMPLS) networks to
determine the routes of Label Switched Paths (LSPs) through the
network.  In this context a PCC may be a Label Switching Router
(LSR), a Network Management System (NMS), or another PCE.  The Path
Computation Element Communication Protocol (PCEP) is specified for
communications between PCCs and PCEs, and between cooperating PCEs.

When computing or re-optimizing the routes of a set of TE LSPs
through a network it may be advantageous to perform bulk path
computations in order to avoid blocking problems and to achieve more
optimal network-wide solutions.  Such bulk optimization is termed
Global Concurrent Optimization (GCO).  A GCO is able to
simultaneously consider the entire topology of the network and the
complete set of existing TE LSPs, and their respective constraints,
and look to optimize or re-optimize the entire network to satisfy all
constraints for all TE LSPs.  A GCO may also be applied to some
