Abstract:
An intra-domain routing method in a content centric network (CCN), includes generating a packet requesting information requested by a node, the packet including an area to which the information is to be advertised, and transmitting the packet within the area.
Abstract:
A relay apparatus and a method of selecting a relay node based on learning in a wireless network are provided. A method of selecting a relay node is performed, for example, by the relay apparatus, and includes receiving packet information from a predecessor node and a successor node, and determining whether the relay apparatus is usable as a node optimized to relay a data packet, based on relay quality information (RQI) that is computed based on the received packet information. Techniques for computing RQI information are also provided.
Abstract:
Provided is a communication method for an administration node in a content centric network (CCN). The communication method includes receiving a packet requesting deletion of an invalid content from a requesting node that detects the invalid content, generating a content revocation list including a name of the invalid content and a period of time over which the deletion is to be performed, and flooding a data packet including the content revocation list to the requesting node and a normal node included in the CCN. Also provided are related communications methods for a receiving node and a normal node, as well as the nodes themselves.
Abstract:
Provided is a node and a communication method of the node in a content oriented network (CON) in which the communication method of the node included in the CON may include receiving, at a receiver, a content request packet having a content name comprising hierarchical name components and flat name components, extracting the hierarchical name components and the flat name components from the content request packet, and processing the content request packet using the hierarchical name components and the flat name components.
Abstract:
A method for content discovery of a node in an intra-domain in a content centric network (CCN), includes generating a content request packet including a discovery area in which a search for content requested from the node is to be conducted, and transmitting the content request packet.
