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:
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:
A communication method of a network node for internet protocol (IP) routing compatibility, includes generating a packet including a name of a content that includes first information indicating a location of the content, and second information identifying the content, and transmitting the generated packet.
Abstract:
A method of caching a content in a node in a content-centric network, includes receiving, from a content requester, a content request packet requesting a first chunk of the content, and setting a mark bit indicating whether the node is to cache the first chunk when the first chunk is received. The method further includes receiving, from a content provider, a data packet including the first chunk in response to transmitting the content request packet to the content provider, and caching the first chunk.
Abstract:
Disclosed are a method and corresponding apparatus to operate transmitting and receiving nodes processing a packet including field position information. The packet includes field position information. Provided is the method for operating a transmitting node, including generating a packet comprising location information indicating information about a location corresponding to a field in the packet, and transmitting the packet including the position information.
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:
An attack detection apparatus includes a window size change unit configured to change a size of a window to be applied to traffic, and an abnormal state detection unit configured to detect an abnormal state of the traffic to which the changed window is applied.
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.
