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:
Provided is a content cache managing method and apparatus, and more particularly, a method and an apparatus for managing a content cache by considering network cost in a network. A content cache managing method of transmission equipment that forwards a content data packet may include calculating a cache replacement factor value by using network cost that is incurred in a network path from the transmission equipment to an original content server storing original content data, based on the content data packet that the content data packet is received from neighboring transmission equipment, and managing a cache in the transmission equipment based on the calculated cache replacement factor value or a state of cache in the transmission equipment to store the content data packet.
