Abstract
Network packets may be transmitted from packet sources to packet destinations through a network of switches. The switches may have corresponding flow tables that control how the packets are forwarded through the switches. A controller server may generate network switch forwarding paths for the network packets by modifying the flow tables with entries based on attributes of the network packets and network topology information. The controller server may forward selected packets directly to packet destinations instead of generating the network switch forwarding paths. To determine which packets to directly forward, the controller server may calculate cost metrics associated with the network switch forwarding paths and associated with forwarding network packets directly to packet destinations. The cost metrics may be calculated based on network topology information, network traffic conditions, controller server processing load, packet forwarding delays, an expected number of future network packets, or attributes of the network packets.
