This version of the draft addresses the comments from Olivier about using the Path Computation YANG model in a flat/distributed network (open issue #61 in github).

Text in section 2 has been updated to clarify that the use of the Path Computation YANG model is not restricted to these use cases but can be used in any other use case when deemed useful.
Sections 2.4 and 2.5 have been added to described two additional use cases (thanks to Julien and Olivier).
No changes are required to the current YANG model.

The editors and Olivier are satisfy with these text changes.

Please review and send your comments to the list.

Sergio and Italo (on behalf of co-authors)

> 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 a stateless RPC to
>    request path computation. This model complements the stateful
>    solution defined in [TE-TUNNEL].
> 
>    Moreover this document describes some use cases where a path
>    computation request, via YANG-based protocols (e.g., NETCONF or
>    RESTCONF), can be needed.
