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

A wireless access point apparatus for configuring a multiple data security tunnel, and a system having the same and a method thereof, and more particularly, a technology associated with a wireless access point apparatus that supports a wireless secure throughout all layers in a wireless network section. The wireless access point apparatus for configuring a multiple data security tunnel includes: a control security tunnel managing unit managing a control security tunnel that transfers policies and authentication information for wireless network access control and management; and a multiple data security tunnel managing unit creating a data security tunnel for each of a plurality of wireless terminals, while, creating and managing the multiple data security tunnel for each of application services of the plurality of wireless terminals.

Access point apparatus for configuring multiple security tunnel, and system having the same and method thereof

Provided is a packet forwarding structure for supporting network based content caching of aggregate contents. The packet forwarding structure includes: a forwarding table including forwarding information on a content in order to forward a request packet from a terminal; a request list table transmitting the request packet to a destination node according to the forwarding table when the request packet arrives; a content caching information table including the forwarding table, the request list table, and position information on where a content cashed based on a content ID or a content name is stored; and a content server function block storing the cached content.

Packet forwarding structure and method for supporting network based content caching of aggregate contents

A method of controlling traffic, particularly, a method of setting and executing a traffic control policy in which a time condition is additionally combined is provided. At any specific step of a network that executes a time-based policy, an execution time point of the time-based policy can be determined. Further, a network service provider can provide various application services to a network user using a time-based policy.

Method of controlling traffic by time-based policy

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

In an environment in which tag readers are installed at a plurality of locations, communication between a tag reader and a terminal including a near field communication (NFC) tag capable of bi-communication with a tag reader is triggered. The tag reader transmits user information and location information which was provided to the terminal to a location information management server so that a service based on the information is provided.

Method and apparatus for obtaining and processing location information with near field communication

The present invention provides an apparatus and a method for an integrated developing environment for a network application, including: an application storing part to store an application produced by a user; an application attribute managing part to manage attribute information for the application; a target code creating part to compile the application stored in the application storing part based on the attribute information stored in the application attribute managing part and create a target code corresponding to the compiled application; and a code loading part to mount the target code created by the target code creating part in hardware.

Apparatus and method for providing integrated development environment for network application using various network processors, and server using the same

In a system for providing an IPTV service, if a multicast address of an IPTV channel received from a head-end is a multicast address requested by a mobile node through a tunnel, an end router confirms a care of address (CoA) of the mobile node corresponding to the multicast address of the IPTV channel, sets the multicast address in the first header of broadcasting traffic, sets the CoA of the mobile node in the second header of the broadcasting traffic, and then sends the broadcasting traffic.

System and method for providing IPTV service

A device for providing forwarding and QoS information in a flow based network environment acquires first information and second information from a flow table therein on the basis of status information of a predetermined flow in order to provide dynamically updated information in a flow based network environment. When it is determined that first information and second information acquired based on a route ID of a series of information are updated, the flow table is updated and the updated information is provided.
