Abstract: The present invention relates to a method and a device for fast forwarding a flow traffic in an information-centric networking (ICN). According to the present invention, a flow switching method for a network node of an information-centric networking (ICN) includes: identifying a data name contained in a received interest packet and identifying a flow name from the data name, thereby determining whether a flow entry corresponding to the identified flow name is present within a flow table (FT); identifying forwarding information base (FIB) entry information matched to the flow name from the corresponding flow entry and identifying an FIB entry corresponding to the FIB entry information; and transmitting the interest packet on the basis of interface information included in the identified FIB entry.

Abstract: The present invention relates to a method for announce-pull data broadcasting in a blockchain based on information-centric networking (ICN). The present invention includes, transmitting announcement messages to notify having any data in the format of an ICN Interest packet, by a blockchain node, to the blockchain node's peers; receiving, by the blockchain node, data request messages, which request the data, from the blockchain node's peers, wherein data request messages for the same ICN Data packet receiving from multiple blockchain nodes can be aggregated at a middle ICN node; and transmitting, by the blockchain node, the ICN Data packet corresponding to the data request message to the blockchain node's peers, wherein the ICN Data packets can cached at the middle ICN node.

Abstract: Disclosed herein a method for configuration of semi-managed DHT based on NDN and system therefor. The method includes: managing and sharing manager nodes based on global information; generating a sub-range segment by partitioning a keyspace area, according to each group of the data peer nodes; managing the sub-range segment by distributing the sub-range segment corresponding to each group to data peer nodes of the each group; checking and analyzing liveness of the data peer node in the each group; estimating availability of the data peer nodes by predicting lifetime of data peer nodes through the checking and analyzing of liveliness; performing risk factor prediction that estimates data availability and sub-range management overhead; and performing a sub-range management decision at each of the manager nodes based on a result of the risk factor prediction, and performing a global stabilization decision required for global system stabilization.

Abstract: Disclosed herein are a packet path selecting method and apparatus in an information-centric network. A packet path selecting method performed by a terminal in an information-centric network includes obtaining information on a network connected with the terminal, transmitting a packet for intra-network path selecting to a node of the network, and receiving a reply packet for intra-network path selecting from the node. The packet for intra-network path selecting includes information on a previous network of the terminal and information on a current network of the terminal.
