Implementations generally relate methods, systems, and computer readable media for discovery of an open network adapter. In some implementations, a method includes receiving, by a software-defined network (SDN) controller, a notification of an open networking adapter (ONA) establishing a connection with a switch, the ONA having an address associated therewith. The method further includes identifying the switch based on a lookup of the address of the ONA in forwarding tables of a neighboring switch of the SDN controller. The method further includes applying a service profile configuration to a port of the switch where the ONA is connected.

Methods, systems and computer readable media for efficient state change support for hierarchical data models in a virtualized system are described. In some implementations, the method can include determining a system status including a system-level bit masked word having a plurality of bits, each bit corresponding to a status of a different hierarchical level of the system, and receiving a change notification. The method can also include querying an entity at a lower hierarchy level if a cascaded state change is identified for that entity. The method can further include continuing to query one or more entities in successively lower hierarchy levels so long as a cascaded state change is identified for a corresponding entity in a lower hierarchy level. The method can also include determining the current status for one or more entities having a changed status. Identifying a cascaded state change can include performing a logical exclusive OR operation on a previous status bit masked word and a current status bit masked word of an entity.
