Abstract
There are scenarios, typically in a hierarchical SDN context, in
which an orchestrator may not have detailed information to be able
to perform an end-to-end path computation and would need to request
lower layer/domain controllers to calculate some (partial) feasible
paths.
Multiple protocol solutions can be used for communication between
different controller hierarchical levels. This document assumes that
the controllers are communicating using YANG-based protocols (e.g.,
NETCONF or RESTCONF).
This document describes some use cases where a path computation
request, via YANG-based protocols (e.g., NETCONF or RESTCONF), can
be needed.
This document also proposes a yang model for a stateless RPC which
complements the stateful solution defined in [TE-TUNNEL].
