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.
