The present invention provides content providing apparatus and method and a content providing system which maintains a compatibility with an IP network and deliver a content with a complete distributed architecture excluding the content synchronizing process and the request routing process which delivers the content.

Apparatus and method for providing content with a distributed architecture, and system for providing content with the said apparatus

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.

Method for providing quality of service in software-defined networking based network and apparatus using the same

Provided is an access mediator system for mediating convergence services of communication and broadcasting using a non-communicative appliance. The access mediator system includes: a non-communicative appliance access interface unit performing an interface function so as to converge a non-communicative appliance comprising an interface supporting image and voice multimedia data but not including a communication function; a broadband convergence network access interface unit performing an interface function so as to access a broadband convergence network connected to various service provider servers via wire and wireless interfaces; and a main processor accessing a selected service provider server via the broadband convergence network access interface unit to mediate the selected service provider server and the non-communicative appliance.
