Abstract
A software-defined networking (SDN) OpenFlow apparatus comprises a processor, and a memory system coupled to the processor and comprising a flow pipeline, wherein the flow pipeline comprises a series of flow tables, wherein each of the flow tables comprises at least one match field, wherein the match fields correspond to a plurality of network services, wherein the match fields are ordered based on a prioritization of the network services, which of the match fields are shared among the network services, a shared dependency of the match fields, and processing speed, and wherein the prioritization is based on which network services are most important and which network services are most frequently used.
