With the NFV paradigm, network services are usually instantiated in datacenters (e.g., as VMs), while softwaredefined networks provide just plain connectivity. However, common SDN controllers can do much more than just traffic steering; particularly they can execute network applications such as NAT, DHCP, and more. This paper presents a software architecture that can advertise an SDN domain as having compute capabilities, hence enabling an overarching multi-domain orchestrator to instantiate a
