摘要
A method for controlling a data flow in a domain of an OpenFlow protocol controlled software-defined network (SDN) comprising receiving a request from a network element for instructions to route the data flow through the OpenFlow SDN, determining a route for the data flow through the OpenFlow SDN, transmitting a unified header to the network element in the OpenFlow SDN, wherein the unified header facilitates transmission of data flows through the OpenFlow SDN that are encoded according to a plurality of network abstraction types, and transmitting instructions for forwarding the data flow along the route through the OpenFlow SDN, wherein the instructions for forwarding the data flow along the route through the OpenFlow SDN comprise one or more match fields, one or more mask values corresponding to the match fields, and one or more actions for the network element in the OpenFlow SDN to perform on the data flow.
