Abstract
Disclosed is a Quality of Service (QoS) providing method and apparatus in a software-defined networking (SDN) based network, the QoS providing method including receiving a first packet of a predetermined flow, searching for forwarding information corresponding to the packet and QoS rule information corresponding to the packet in a forwarding table and a QoS rule table, respectively, transmitting the packet to a controller if the forwarding information and the QoS rule information do not exist in the forwarding table and the QoS rule table, and generating a flow entry corresponding to the packet in a flow learning table based on forwarding information and QoS rule information that are received from the controller, thereby efficiently providing QoS.
