METHOD AND SYSTEM FOR DELIVERING CONTENTS

The present invention relates to a method and an apparatus for delivering contents over a named data network (NDN). According to a first aspect of the present invention, a method for delivering contents in a content delivery system configured to deliver packets from one node to another node, based on an open flow network system including multiple nodes configured to transmit and receive packets using content names, a switch device configured to relay a flow transmission/reception among the multiple nodes, and a controller device configured to control the switch device, comprises the following steps. When a packet is received, the switch device determines whether the received packet is a packet to be delivered over the NDN. And, when the received packet is the packet to be delivered over the NDN, the switch device acts as an entity of the NDN based on a type of the packet. By using the present invention, an NDN which utilizes a pre-established network is configured.
