Using a representational state transfer services framework (REST), embodiments of the present invention can improve interoperability between SDN controllers and network devices (e. g., physical switches, routers, etc. ) of different vendors through the use of dynamically created logical switches loaded from the SDN controller. Embodiments of the present invention allow the SDN controller to serve a plurality of different network device types a logical switch directly or can redirect them to another controller/repository, e. g. for load balancing. After loading the logical switches on the network devices in the manner described by embodiments of the present invention, a network administrator can remotely invoke various services defined in the logical switches which also allow the administrator to configure network devices automatically. By increasing interoperability between network devices in this fashion, a SDN can evolve or change services dynamically in a manner that also saves memory and allows for improved network security. |
