Abstract:
A routing control method in software defined networking and an OpenFlow controller are provided. The method includes: receiving, by an OFC, a data packet reported by an OFS; determining, by the OFC according to a key value stored in a cache, whether the data packet is a repeated packet; and if the data packet is a repeated packet, delivering, by the OFC, the data packet to the OFS, and instructing the OFS to match a stored flow table to process the data packet or transmit the data packet through a corresponding port; or if the data packet is not a repeated packet, calculating, by the OFC, a routing policy for the data packet, and delivering a flow entry to the OFS according to the routing policy. In this way, for repeated packets, the OFC may calculate a routing policy only once, thereby reducing a calculation amount of the OFC.

Claim (Index 14):
The controller according to  claim 12 , wherein:\n the key value further comprises a processing moment; and the processor is configured to invoke the execution instruction in the memory causing the OpenFlow controller to:\n compare a feature value of the first data packet with the data packet feature value in the key value, \n determine that the feature value of the first data packet is the same as the data packet feature value in the key value, and \n determine a time interval between a current moment and the processing moment in the key value is less than or equal to a preset time value, wherein the preset time value is a time value less than or equal to a flow table valid time.
