摘要:
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.

Provided is a communication method of a terminal, including generating, based on a characteristic of an application executed by at least one terminal in a virtual group, a content request message to request content stored by one or more other terminals in the virtual group, and transmitting the content request message to an intermediate node managing the at least one terminal to receive the content stored by the one or more other terminals.

Provided are a network apparatus and system that may request or receive the same contents stored in a plurality of network apparatuses. In a network system sharing data, specific segments from a plurality of segments constituting the data may be received from mutually different terminals. For this, a transmission region may be determined by calculating a transmission offset corresponding to the plurality of terminals, and at least one segment included in the determined transmission region may be received from a corresponding terminal.

Provided are a content source node and a first content router and a second content router in a content centric network (CCN), and a communication method thereof. The technology described herein may reduce the updating of routing information due to a movement of a mobile source node and the corresponding overhead, thereby reducing a rate of using an overall network resource by adding routing information, that is, partially updating the routing information of the corresponding mobile source node for content routers on a route through which the mobile source node moves.
摘要:
A target node and a communication method of using a target node that is configured to prefetch a segment of content in a Content-Centric Network (CCN) are provided. A communication method involving a target node configured to prefetch a segment of content in a Content-Centric Network (CCN) involves: receiving, from a previous node, a predetermined content-request packet requesting a predetermined segment of a content; determining a prefetching window size based on a number of segments in response to the predetermined content-request packet, the segments being prefetched based on a name of the content; generating a content-request packet that requests each of the segments based on the prefetching window size; and transmitting the generated content-request packet to a next node.
摘要:
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.
摘要:
A node and a method for transmitting and receiving a Content-Centric Network (CCN) packet in a CCN are provided. The method of transmitting the CCN packet, includes generating a path being used to transmit a packet with a compressed header. The method further includes determining whether a header of the CCN packet is compressible. The method further includes compressing the header based on a result of the determining. The method further includes transmitting the CCN packet with the compressed header via the path.
摘要:
A method and apparatus to process interest messages and data messages based on priorities in a Content-Centric Network (CCN) are provided. The method and apparatus to process interest messages and data messages based on priorities in a CCN provides different Quality of Service (QoS) based on type of contents by extracting a traffic type of each of the contents.
摘要:
A method of implementing a Content-Centric Network (CCN) using an Internet Protocol (IP)-based network, and a gateway that may implement such a method, are provided. A method of implementing a CCN using an IP-based network may involve: determining an application protocol and a packet type corresponding to the application protocol of an IP-based network, the application protocol being included in an IP packet of an IP-based network, and generating a content name corresponding to the IP packet, based on the application protocol and the packet type.
摘要:
A method and apparatus for controlling operation of a reception node in a content centric network (CCN) and for content included in the reception node using an operation identifier (OID) are provided. The OID may designate at least one control operation to be performed by the reception node.
