NETWORK DEVICE CONTROL IN A SOFTWARE DEFINED NETWORK

摘要

A technique for programming or querying a network device in a Software Defined Network (SDN) via a communications protocol is provided. A method realization of that technique implemented by a controller of the SDN comprises the step of creating at least one template for a type message defined by the communications protocol. The template predefines at least one value for at least one parameter conveyed by that type of message. The at least one template is sent to the network device for installation by that network device. The communications protocol may be one of the OpenFlow protocol and the ForCES Forwarding Element Model protocol as defined in RFC 5812.
