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.
