Abstract:
Provided are communication devices and methods for requesting content in a network based on a hierarchical name structure. A content requester may search for content without the use of the entire content name in the network based on the hierarchical name structure.
Abstract:
A communication apparatus and method of a content router control a traffic transmission rate in a content-centric network (CCN), and the content router. In the communication method and the content router, a congestion of a network may be predicted, a warning signal indicating the congestion may be added to an interest packet, and the interest packet with the warning signal may be transmitted. Additionally, a traffic transmission rate may be controlled by adjusting a data packet transmission time based on a value of a marked field of a PIT. The PIT is set by receiving an interest packet to which a warning signal is added. Thus, the communication apparatus and method thereof provide reachability, while maintaining stability of network routing.
Abstract:
Provided are an apparatus and a method that differently sets the access authority of a user for individual parts of an online document. For every parts of the online document, the user authority is set and the parts are edited only by a user that can access the part. Finally, the parts of the documents are combined as the final document. According to the present invention, the document is divided into parts and the access authority of the user is variously set, which results in maximizing the efficiency of editing the document. The editors of the individual parts inherit the authorities to other people, so that it is very efficient for the cooperative job of a document in the organization having a hierarchy.
