[Teas] FW: I-D Action: draft-ietf-teas-yang-path-computation-09.txt

Dear TEASers,

we have updated the path computation RPC model to:
- align with the latest version of the TE tunnel YANG model (https://tools.ietf.org/html/draft-ietf-teas-yang-te-23)
- add support of path computation for protected paths (as discussed in IETF 104)
- add support of path computation for bidirectional paths
- returning errors in case path computation fails
- add support for multi-layer path computation

The changes to the YANG model are described in section 5.3 and 5.4 of the 09 version of the draft.

We think that with these changes the model is now ready for YANG doctor review, however due to the significant amount of changes we would appreciate a review from
the WG before asking YANG doctor review.

Thanks
Italo and Sergio (as editors)

Abstract:
   There are scenarios, typically in a hierarchical SDN context, where
   the topology information provided by a TE network provider may not
   be sufficient for its client to perform end-to-end path computation.
   In these cases the client would need to request the provider to
   calculate some (partial) feasible paths.

   This document defines a YANG data model for an RPC to request path
   computation. This model complements the solution, defined in
   RFCXXXX, to configure a TE Tunnel path in "compute-only" mode.

   [RFC EDITOR NOTE: Please replace RFC XXXX with the RFC number of
   draft-ietf-teas-yang-te once it has been published.

   Moreover this document describes some use cases where a path
   computation request, via YANG-based protocols (e.g., NETCONF or
   RESTCONF), can be needed.
