Hi Young,

1) in case of stateful PCE, is it mandatory to include the full list of RROs in 
the PCReq message?

2) In section 2, Terminology, GCO is defined to consider only the entire 
network, while in the rest of the document also network subsets are allowed. 
Is the use of "Global" associated to both the cases of entire network and 
network subsets or is it just related to the entire network?

Thank you
  Filippo

  Hi J-P and Adrian, 

   

  Here's the update of PCE GCO draft. As per requested in Philadelphia, this is 
ready for the WG chair's review and the last call. Please note section 9 for 
IANA considerations and new objects/TLV/Flags have been defined. I'd appreciate 
your review and look forward to making progress on this work to the next stage. 
Thanks. 

   

  I snipped Section 9 below. Thanks.

   

  Regards,

  Young

  9.  IANA Considerations

   

     IANA maintains a registry of PCEP parameters.  IANA is requested to

     make allocations from the sub-registries as described in the

     following sections.

   

  9.1.  Request Parameter Bit Flags

   

     As described in Section 5.3, two new bit lfags are defined for

     inclusion in the Flags field of the RP object.  IANA is requested to

     make the following allocations from the "Request Parameter Bit Flags"

     sub-registry.

   

   

     Bit      Name    Description                    Reference

   

     11       D-bit   Report the request order       [This.I-D]

     12       M-bit   Make-before-break              [This.I-D]

   

   

  9.2.  New PCEP TLV

   

     As described in Section 5.4, a new PCEP TLV is defined to indicate

     the setup and delete order of LSPs in a GCO.  IANA is requested to

     make the following allocation from the "PCEP TLV Types" sub-registry.

   

   

     TLV Type        Meaning                 Reference

   

     5               Order TLV               [This.I-D]

   

   

  9.3.  New PCEP Object

   

     As descried in Section 5.5, a new PCEP object is defined to carry

     global constraints.  IANA is requested to make the following

     allocation from the "PCEP Objects" sub-registry.

   

   

     Object  Name                                            Reference

     Class

   

     24              GLOBAL-CONSTRAINTS                      [This.I-D]

                         Object-Type

                        1: Global Constraints                [This.I-D]

   

  9.4.  New PCEP Error Codes

   

     As described in Section 5.6, new PCEP error codes are defined for GCO

     errors.  IANA is requested to make allocations from the "PCEP Error

     Types and Values" sub-registry as set out in the following sections.

   

  9.4.1.  New Error-Values for Existing Error-Types

   

   

     Error

     Type    Meaning                                            Reference

   

     5               Policy violation

                             Error-value=5:                     [This.I-D]

                     Global concurrent optimization not allowed

   

   

  9.4.2.  New Error-Types and Error-Values

   

   

     Error

     Type    Meaning                                            Reference

   

     15              Global Concurrent Optimization Error       [This.I-D]

                     Error-value=1:

                     Insufficient memory                        [This.I-D]

                     Error-value=2:

                     Global concurrent optimization not supported

                                                                [This.I-D]

   

   

  9.5.  New No-Path Reasons

   

     IANA is requested to make the following allocations from the "No-Path

     Reasons" sub-registry for bit flags carried in the NO-PATH-VECTOR TLV

     in the PCEP NO-PATH object as described in Section 5.7.

   

     Bit

     Number          Name                         Reference

   

     6               No GCO migration path found  [This.I-D]

     7               No GCO solution found        [This.I-D]
