| Abstract(in English) | We propose a method to filter out packets of heavy flows forwarded to the controller in OpenFlow switches to reduce switch processing loads and the amount of control traffic in OpenFlow networks. In OpenFlow, a switch forwards packets unmatched with any flow entries to the controller. This process increases switch processing loads and the amount of control traffic when a host connected to the switch starts sending heavyflows. A simple method to prevent this problem is to limit the rate of total Packet-In messages, but such method drops packets of other flows if packets of heavy flows and other flows are sent to the controller simultaneously. We propose a method to pass through packets of other flows with priority in switches by recording flows whose packets are sent to the controller, and by limiting the rate of packets matched with recorded flows. |
