Abstract: A method for processing a query by accessing information by use of an Information-Centric Network (ICN) includes requesting, by a user device, a file by providing a local storage system with an identifier of the file; determining whether the local storage system stores the requested file; and generating, by the local gateway, an information request message including the identifier of the requested file if it is determined that the local storage system does not store the requested file, and providing the ICN with the generated information requested message. Accordingly, architecture expansion is easily achieved without a large scale update of information since there is no need to share information about a file list of each storage system as a whole, and a data query task is performed on a plurality of unspecified storage systems without establishing a one-to-one connection between end points of storage systems.
