Abstract: Provided are methods of managing and storing distributed files based on an information-centric network (ICN). A method of managing distributed files performed by an ICN node includes receiving a message for requesting provision of data from a first network node, determining whether a name of the requested data is identical to a name of data stored in the ICN node, and adaptively providing the data to the first network node based on a result of the determination. Accordingly, it is possible to reduce the overall network load by preventing duplication of a data access path.

Abstract: Disclosed is a virtual file system for interworking between a content server and an information-centric network server, the system including: a file system function processing unit configured to process a file operation for a predetermined content requested from a plurality of content service protocols; a cache control unit configured to process the content requested through the file operation by managing a cache in a node; and a protocol matching unit configured to process the content requested through the file operation by interfacing with a plurality of content transfer protocols.

Abstract: In order to easily prevent traffic of a content data server, which provides an arbitrary content, from being overloaded, the content transmission system according to an exemplary embodiment includes a content data server which provides an arbitrary content to a plurality of terminals when a request signal for the arbitrary content is input from the plurality of terminals, a data control server which when the arbitrary content is provided, monitors whether the traffic of the content data server is overloaded and if the traffic is overloaded as a result of monitoring, generates a traffic distribution request signal, and a node control server which when the traffic distribution request signal is input from the data control server, controls to provide the arbitrary content to an arbitrary distribution node, which satisfies a setting standard among a plurality of distribution nodes, to be provided to an arbitrary terminal among the plurality of terminals.

Abstract: The present invention relates to a content providing system and method combining a transparent Internet cache (TIC) server and a content delivery network (CDN), and more particularly, to a content providing system and method that may overcome limitation on capacity of a cache storage found in a TIC service and may also overcome limitation on service transparency found in a CDN service. According to the present invention, it is possible to overcome limitation on capacity of a cache storage found in an existing TIC service and to overcome limitation on service transparency found in a CDN by combining a TIC server and the CDN.

Abstract: Disclosed are an apparatus for configuring an overlay network and a method thereof. An apparatus for configuring an overlay network may include a network configuring device collecting topology information and bandwidth information of a physical network and configuring one logical network including a plurality of predetermined nodes by using the collected topology information and bandwidth information of the physical network; and a storage device storing the topology information and bandwidth information of the physical network.

Abstract: An apparatus and method of controlling virtual private network (VPN) services are provided. The apparatus according to an embodiment of the present invention includes a profile definition unit that defines a service profile required for VPN setting between edge devices connected to a carrier ethernet backbone network via an access network, and a VPN setting and management unit that sets a VPN connecting the carrier ethernet backbone network and the access network based on the service profile defined by the profile definition unit, and centrally manages the carrier ethernet backbone network and the access network to provide the VPN services.
