Abstract
A method is executed by a network device in a network including a plurality of network devices. The network device implements a software defined networking (SDN) controller, where the SDN controller controls a first switch and a second switch in a network. The method improves packet processing performance in the network by reorganizing flow entries to decrease time to match active flows. The method includes receiving flow statistics for a first flow from the first switch, determining, based on the flow statistics for the first flow, that the first flow has a traffic usage that exceeds a pre-defined threshold, and in response to determining that the first flow has a traffic usage that exceeds the pre-defined threshold, programming the second switch to create a new flow table for processing the first flow or to increase a priority for matching a flow entry for the first flow within an existing flow table.
