Abstract
Methods and apparatus for using dynamic programming to determine the most efficient mapping of a pipeline of virtual flow tables (VFTs) onto a pipeline of physical flow tables (PFTs) in the data plane of a software-defined networking (SDN) device are described. One example method of determining a configuration for an SDN device generally includes receiving a representation of a series of one or more VFTs, each of the VFTs having one or more properties; receiving a representation of a series of one or more PFTs for hardware of the SDN device, each of the PFTs having one or more capabilities; generating, using dynamic programming based on the properties of the VFTs and the capabilities of the PFTs, a mapping of the series of VFTs onto the series of PFTs; and outputting the generated mapping for implementation on the hardware of the SDN device.
