Abstract:
The present disclosure relates to the communications field, and specifically, to a flow table processing method and an apparatus. The method includes: monitoring, by a switch, a flow table load of the switch; when the flow table load of the switch exceeds a preset threshold, determining, by the switch, a diffusion target of a target data flow according to a matching rule of a diffusive flow table; and when the determined diffusion target is a neighboring switch of the switch, forwarding, by the switch, the target data flow to the neighboring switch. When the flow table load of the switch exceeds the preset threshold, the switch may have been attacked. A data flow that fails to be matched to a flow entry is forwarded to the neighboring switch according to a diffusion probability, for processing by the neighboring switch.

Claim (Index 19):
A controller, wherein the controller is applied to a software-defined network (SDN), the SDN comprises the controller and multiple switches, and the controller comprises a determining unit, an obtaining unit, and a sending unit;\n the determining unit is configured to determine, according to a network topology, a second switch directly connected to a first switch, wherein the first switch is any switch of the multiple switches, the second switch is a switch other than the first switch in the multiple switches, and there is at least one second switch; the obtaining unit is configured to obtain a flow table load of the second switch; the determining unit is further configured to determine a diffusive flow table of the first switch according to the load of the second switch; and the sending unit is configured to send the diffusive flow table to the first switch.
