Abstract
Disclosed is a method for updating a flow table for a switch in software defined networking (SDN). The method for updating a flow table of at least one network device by a controller in a software defined network comprises the steps of: transmitting, to at least one network device, a flow table modification message including information on a scheduled time specifying a time at which updating of the flow table is performed; and receiving, from at least one network device, a result message showing an update result on the flow table performed by at least one network device according to the flow table modification message. Accordingly, it is possible to effectively control a load generated on the controller by controlling intervals of updating times between network devices, which is generated during transmission of the flow table modification message to multiple network devices.
