Re: [Pce] I-D Action: draft-ietf-pce-stateful-interdomain-02.txt

Dear all, We just published a new version of draft-ietf-pce-stateful-interdomain. This revision 2 takes into account the recommendations about how to convey the Stitching Label. As decided following the discussion on the mailing list, the draft has been updated to use the TE-PATH-BINDING TLV to request and convey the Stiching Label as a Binding Value. Main modification concerns: - Section 2 to explainhow to use the TE-PATH-BINDING TLV and to define 2 new flagsfor Binding Value. Some texts have been also move from section 6 to section 2to explain how to steer traffic at inter-domain. This includes  both RSVP-TE and Segment Routing use case. - Section 3 and 4 to adapt the distributed and centralised use case accordingly  to section 2. Both use case have been generalized to RSVP-TE and Segment Routing for local path enforcement. - Section 6 to explain in which condition a domain could Nested inter-domain traffic. - Section 7 to adapt IANA requests according to section 2. As usual, comments are welcome.

Regards

Olivier, on behalf of authors

> Abstract:
>    This document specifies how to use a Backward Recursive or
>    Hierarchical method to derive inter-domain paths in the context of
>    stateful Path Computation Element (PCE).  The mechanism relies on the
>    PCInitiate message to set up independent paths per domain.  Combining
>    these different paths together enables them to be operated as end-to-
>    end inter-domain paths, without the need for a signaling session
>    between inter-domain border routers.  For this purpose, this document
>    defines a new Stitching Label, new Association Type, and a new PCEP
>    communication Protocol (PCEP) Capability.
