The PCE working group of the IETF would like to keep your members informed of the progress of the working group. We have three RFCs that have recently been published: http://www.ietf.org/rfc/rfc4655.txt is the general architecture for PCE in MPLS-TE and GMPLS networks. http://www.ietf.org/rfc/rfc4657.txt describes generic requirements for a communication protocols operating between PCCs and PCEs, and between cooperating PCEs. Additional specific requirements for particular deployment scenarios (such as inter-area, inter-AS, multi-layer, etc.) are covered in separate Internet-Drafts. http://www.ietf.org/rfc/rfc4674.txt sets out the requirements for discovery of PCEs and their capabilities. In addition, the working group is very active in specifying application-specific uses of PCE, a policy-related framework, and protocols, protocol extensions, monitroing, and management in support of PCE. We would welcome input from all OIF participants. Ideas, opinions, and contributions should be sent to the PCE email list. Details of how to join the mailing list can be found at the PCE charter page (http://www.ietf.org/html.charters/pce-charter.html) which also provides pointers to all of the current PCE Internet-Drafts.

Mach,

A question about the pce sequence = autoexplore I-D.

 

This method seems to rely on BGP to = get the next AS en-route to the destination. BGP may not give all the = possible ASes, since based on its decision process and policy it may select only one = route to pass on. For ex. If an EBGP speaker gets route for the same prefix from different EBGP peers from different ASes, it may select one of them and advertise to its IBGP peers. (The PCE may not have access to all the = alternate routes of the EBGP speaker connecting to all the ASes) But we don't know the TE characteristic of the link connecting with the speaker whos' = route was chosen( it may not be TE capable ?). Also, the policy configuration = on the EBGP speaker itself may block some inbound routes. So some information = is lost here.

 

Regards,

Vijay

HI, Vijay



 



As you said,  the
prime thought for this draft is to find out the connectivity of the ASBRs, this
information can be used for inter-AS TE, for example, if an ERO contained an AS
number as its next hop, how to discover the tail end of the route segment in
local AS for the inter-as TE lsp computation.



 



I can fold your thought in future version



 



Zhang Renhai



                                            



 






 



Mach,

A question regarding your I-D.



 



The mechanism you
described only finds out the connectivity of the ASBRs. It does not discover
the TE characteristics of the inter-AS links, for ex. the link bandwidth,
colour etc. which may be needed to decide if an inter-AS link can be used for
TE paths.  





Regards,



Vijay

Subject: [PCE] About ASBR locate



 









Hi folks,









 









We have posted a new I-D which is about how
to get the ASBR info which are
used to compute TE LSP in an Inter-AS scenario.









 









Any feed-back and comments would be most
welcome!









 









Best regards,

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
 
 
  Title                : Locate ASBR in PCE 
  Author(s)          : R. Zhang, M. Chen
  Filename : draft-zhang-pce-locate-asbr-00.txt
  Pages              : 8
  Date                : 2006-10-12
  
   The ability to compute constrained shortest Traffic Engineering (TE) 
   Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) 
   and Generalized MPLS (GMPLS) networks across multiple domains has 
   been identified as a key requirement. This document specifies a 
   procedure for an inter-AS PCE to locate boundary node within its 
   domain dynamically, which is used for path computation.

Dear WGs,

=20

I've posted two new, interrelated IDs proposing a simple extension to
the ERO to allow path segments in separate ASs to remain confidential.
There are indeed various circumstances that require "encoding" a path
segment in some form. I've included the abstracts below. The IDs have
been split into a CCAMP ID specifying just the ERO extensions and the
PCE ID which details the protocol extensions to use Path Keys. The PCE
ID also incorporates feedback from the list including a preliminary look
at security considerations.

Comments are very welcome.

Rich

   Abstract to draft-bradford-ccamp-path-key-ero-00.txt
=20
   Multiprotocol Label Switching (MPLS) Traffic Engineering (TE)
   Label Switched Paths (LSPs) may be computed by Path Computation
   Elements (PCEs). Where the TE LSP crosses multiple domains, such
   as Autonomous Systems (ASs), the path may be computed by multiple
   PCEs that cooperate, with each responsible for computing a segment
   of the path. To preserve confidentiality of topology with each AS,
   the PCE supports a mechanism to hide the contents of a segment of
   a path, called the Confidential Path Segment (CPS), by encoding
   the contents as a Path Key Sub-object (PKS). This draft describes
   the addition of this object to the Explicit Route Object.

   This document defines a mechanism to hide the contents of a

   segment of a path, called the Confidential Path Segment (CPS). The

   CPS may be replaced by a path-key that can be conveyed in the PCE

   Communication Protocol (PCEP) and signaled within in a Resource

   Reservation Protocol (RSVP) explicit route object.

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : A Backward Recursive PCE-based Computation (BRPC) procedure to compute shortest inter-domain Traffic Engineering Label Switched Paths Author(s) : J. Vasseur, et al. Filename : draft-ietf-pce-brpc-01.txt Pages : 15 Date : 2006-10-19 The ability to compute constrained shortest Traffic Engineering (TE) Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) networks across multiple domains (where a domain is referred to as a collection of network elements within a common sphere of address management or path computational responsibility such as IGP areas and Autonomous Systems) has been identified as a key requirement . This document specifies a procedure relying on the use of multiple Path Computation Elements (PCEs) in order to compute such inter-domain shortest constraint paths along a determined sequence of domains, using a backward recursive path computation technique while preserving confidentiality across domains, which is sometimes required when domains are managed by different Service Providers.

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCC-PCE Communication Requirements for Inter-Layer Traffic Engineering Author(s) : E. Oki Filename : draft-ietf-pce-inter-layer-req-03.txt Pages : 8 Date : 2006-10-22 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 service 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". This document complements the generic requirements and presents a detailed set of PCC-PCE communication protocol requirements for inter-layer traffic engineering.

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-02.txt Pages : 0 Date : 2006-10-22 A network may comprise of multiple layers. It is important to globally optimize network resources 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 path computation architecture to inter-layer MPLS and 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).

Additional specific requirements for particular deployment scenarios (such as inter-area, inter-AS, multi-layer, etc.) are covered in separate Internet-Drafts. http://www.ietf.org/rfc/rfc4674.txt sets out the requirements for discovery of PCEs and their capabilities. In addition, the working group is very active in specifying application-specific uses of PCE, a policy-related framework, and protocols, protocol extensions, monitroing, and management in support of PCE. We would welcome input from all ITU-T participants. Ideas, opinions, and contributions should be sent to the PCE email list. Details of how to join the mailing list can be found at the PCE charter page (http://www.ietf.org/html.charters/pce-charter.html) which also provides pointers to all of the current PCE Internet-Drafts. In the light of G.7715.2, it may be that your members are interested in seeing how the existing PCE protocol work can be applied to meet your requirements.

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-03.txt Pages : 10 Date : 2006-10-23 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) based architecture is the computation of inter-area TE-LSP paths. 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.

Oki Filename : draft-ietf-pce-inter-layer-req-03.txt Pages : 8 Date : 2006-10-22 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 service 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". This document complements the generic requirements and presents a detailed set of PCC-PCE communication protocol requirements for inter-layer traffic engineering.

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCC-PCE Communication Requirements for Inter-Layer Traffic Engineering Author(s) : E. Oki Filename : draft-ietf-pce-inter-layer-req-03.txt Pages : 8 Date : 2006-10-22 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 service 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". This document complements the generic requirements and presents a detailed set of PCC-PCE communication protocol requirements for inter-layer traffic engineering.

I have several comments. 1. Section 3.2: The last sentense The SVEC, RP, END-POINTS, LSPA, BANDWIDTH, METRIC, ERO, IRO and LOAD- BALANCING objects are defined in [I-D.ietf-pce-pcep]. is not neccessary, as these objects do not appear in PCMonRep. 2. Section 4.1 describes P (Processing Time) - 1 bit: the P bit of the MONITORING object carried in a PCMonReq message is set to indicate that the processing... "or a PCReq message" would be added after "a PCMonReq message". 3. Section 4.3 describes When the processing time is requested in addition to a path computation, the PROC-TIME object always report the actual processing time for that request and thus the E bits MUST be cleared. Is it possible to define "actulal" Min- Max- Average- procssing time with E=0? Otherwise, when E is cleared, Min- Max- Average- procssing time MUST be set to 0x00000000. In other words, If the G flag of the MONITORING object is set then E bit MUST be cleared. Please clarify it. 4. Section 4.1 C (Check) - 1 bit: when set, this indicates that the performance metric of interest is the PCE's availability. What does the PCE's availablity mean? If a specific TE LSP computation is requested, does it mean that PCE has the ability to compute the path with the specified constraints? In case of the general computation, does it mean that PCE is alive or not? Please clarify it. Thank you.

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : Inter-AS Requirements for the Path Computation Element Communication Protocol (PCECP) Author(s) : N. Bitar, et al. Filename : draft-ietf-pce-interas-pcecp-reqs-01.txt Pages : 13 Date : 2006-10-26 Multiprotocol Label Switching Traffic Engineered (MPLS-TE) LabelSwitched Paths (LSPs) may be established wholly within an Autonomous System (AS) or may cross AS boundaries. The Path Computation Element (PCE) is a component that is capable of computing paths for MPLS-TE LSPs. The PCE Communication Protocol(PCECP) is defined to allow communication between Path Computation Clients (PCCs) and PCEs, and between PCEs. The PCECP is used to request paths and to supply computed paths in responses. Generic requirements for the PCECP are set out in "Path Computation Element(PCE) Communication Protocol Generic Requirements", RFC 4657. This document extends those requirements to cover the use of PCECP in support of inter-AS MPLS-TE.

Trust.)

The public ID Nits checker = already accepts I-Ds with old or new
The Secretariat has started = accepting I-Ds with old or new boilerplate

XML2RFC = version 1.32 will generate the new boilerplate.
Users of I-D templates are requested to update them = appropriately.


Starting = December, the public ID Nits checker will issue warnings for=A0
old = boilerplate.

Starting February 2007, the Secretariat will = refuse=A0
the old boilerplate in Internet-Drafts.

We are = sorry for the inconvenience, but this change cannot
be avoided.

None of the issues is sufficiently large to warrant a respin before WG last call, but if you have time over the next two weeks it would be nice for people to have a clean copy to review immediately after San Diego. Thanks, Adrian Minor === Section 3 It is expected that a solution for a PCECP satisfies these requirements. What do we mean here exactly? I think that we mean... Any PCECP solution MUST satisfy the requirements of [RFC4657] and MUST either satisfy the requirements specified in this document of MUST be readily extensible to satisfy these requirements. --- Section 5.1 I think you need to require a failure reason that says "can't compute intra-area path to destination" --- Section 5.2 Hence the response message MUST support the inclusion of the identifiers of the crossed areas and MUST allow identifying the corresponding path segments. Can you add a few words to clarify? What you are asking for is that the returned path be segmented and marked so that it is possible to tell which pieces of the path lie within which area? --- Section 5.4 Need to clarify the intent of the list of preferred PCEs. Is there a requirement that only these PCEs will be used? Is there a requirement that all of these PCEs will be tried before any other is tried? Is there a linkage between the preferred PCEs and the IGP areas? although these questions do not impact on the bits and bytes of the protocol extensions that would be defined, they do change how the protocol procedure extensions will be defined, so you must say something here. --- Section 5.6 I think that for completeness and to ensure that the protocol meets your requirements, you should provide a table of all of the options that you wish to be able to signal. --- Section 5.6 The response message MUST allow indicating the level of diversity of a set of computed loose paths. There is something implicit in this sentence. You are saying that the level of diversity provided may be different from the level of diversity requested (if it was not different, you would not need to provide an indication of the actual diversity). I think this means that the diversity request can be exactly a request, not a demand. So you need to clarify. Does the path computation request message have "desired diversity" and "required diversity" constraints as separate fields? --- Section 5.7 There is a mention of AS-crossing. Is that in scope? --- Section 5.7 How is the second bullet different from the first paragraph of section 5.1? --- Do you need to add the ability to list areas that are to be explicitly excluded form the path? --- Section 6 I think you are adding requirements for a few extra things to be visible/manageable through the MIB modules. Which things? Which MIB modules? --- Nits ==== Title The RFC Editor is still not ready to accept that MPLS and GMPLS are well-known terms, so the title needs to change to... Path Computation Element Communication Protocol (PCECP) Specific Requirements for Inter-Area Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering --- Abstract You need to expand the following acronyms in the abstract... IGP TE LSP LSR --- Abstract OLD 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. NEW In a multi-area network, topology visibility remains local to a given area, and a head-end LSR cannot compute an inter-area shortest constrained path. --- Abstract I think you should add a sentence to explain where PCECP fits in. For example... One key application of the Path Computation Element (PCE) based architecture is the computation of inter-area TE-LSP paths. ** The PCE Communication Protocol (PCECP) is used to communicate computation requests from PCE clients to PCE servers and to return computed paths in responses.*** This document lists a detailed set of PCECP specific requirements for support of inter-area TE-LSP path computation. --- Abstract It complements generic requirements for a PCE Communication Protocol. s/generic/the generic/ --- Section 1 I suggest you remove this as the Gen Art reviewers keep objecting. You have section 12 anyway. --- Section 2 Add ERO --- Section 3 OLD The main challenge with inter-area MPLS-TE relies actually on path computation. NEW The main challenge with inter-area MPLS-TE lies in path computation. --- Section 3 OLD Indeed the head-end LSR cannot compute a constrained path across areas, as its topology visibility is limited to its own area. NEW Indeed the head-end LSR cannot compute an explicit path across areas, as its topology visibility is limited to its own area. --- Section 3 The generic requirements for a PCE Communication Protocol (PCECP), which allows a PCC to send path computation requests to a PCE and the PCE to sent path computation responses to a PCC, are set forth in [RFC4657]. s/sent/send/ --- Section 3 Note that PCE-based inter-area path computation may require a mechanism for an automatic PCE discovery across areas, which is out of the scope of this document. s/for an automatic/for automatic/ --- Section 4 OLD IGP hierarchy allows improving IGP scalability, by dividing the IGP domain into areas and limiting the flooding scope of topology information to area boundaries. A router in an area has full topology information for its own area but only reachability to destinations in other areas._ Thus, a head-end LSR cannot compute an end-to-end constrained path that traverses more than one IGP area. NEW IGP hierarchy enables improved IGP scalability by dividing the IGP domain into areas and limiting the flooding scope of topology information to within area boundaries. A router in an area has full topology information for its own area, but only information about reachability to destinations in other areas. Thus, a head-end LSR cannot compute an end-to-end path that crosses the boundary of its IGP area. --- Section 4 OLD A solution for computing inter-area TE-LSP path currently relies on a per domain path computation ([PD-COMP]). It is based on loose hop routing with an ERO expansion on each ABR. This can allow setting up a constrained path, but faces two major limitations: - This does not allow computing an optimal constrained path; - This may lead to several crankback signaling messages and hence delay the LSP setup, and also invoke possible alternate routing activities. NEW A current solution for computing inter-area TE-LSP path relies on a per domain path computation mechanism ([PD-COMP]). It is based on loose hop routing with an ERO expansion on each ABR. This allows an LSP to be set up following a contrained path, but faces two major limitations: - This does not guarantee the use of an optimal constrained path; - This may lead to several crankback signaling messages and hence delay the LSP setup, and may also invoke possible alternate routing activities. --- Section 4 OLD The PCE based architecture [RFC4655] is well suited to inter-area path computation, as it allows overcoming the path computation limitations resulting from the limited topology visibility, by introducing path computation entities with more topology visibility, or by allowing cooperation between path computation entities in each area. NEW The PCE based architecture [RFC4655] is well suited to inter-area path computation, as it allows the path computation limitations resulting from the limited topology visibility to be overcome by introducing path computation entities with more topology visibility, or by allowing cooperation between path computation entities in each area. --- Section 4 OLD - Single PCE computation: The path is computed by a single PCE that has topology visibility in all areas and can alone compute an end- to-end optimal constrained path.

A Path Computation Element (PCE) based architecture has been
   specified for the computation of Traffic Engineering (TE) Label
   Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) and
   Generalized MPLS (GMPLS) networks in the context of single or
   multiple domains (where a domain is referred to as a collection of
   network elements within a common sphere of address management or path
   computational responsibility such as IGP areas and Autonomous
   Systems).  In such PCE-based environment it is thus critical to
   monitor the state of the path computation chain and potentially
   gather various performance metrics with regards to the set of
   involved PCE(s) that can be used for performance monitoring and
   troubleshooting purposes.  This document specifies procedures and
   extensions to the Path Computation Element Protocol (PCEP) in order
