Abstract: Disclosed herein a source routing apparatus and method in ICN. The method includes: receiving an interest packet; extracting a current entry value when the received interest packet includes a forwarding hint; using the extracted current entry value as an index of a path list; extracting a name of the interest packet; reducing the current entry value when the interest packet is transmitted to a network area of the path list; performing a FIB lookup with the extracted name; determining an output port using the FIB lookup; and transmitting the interest packet to the output port.

Abstract: According to an embodiment of the present disclosure, there is provided a method for providing a virtual private network service in ICN name-based networking. The method comprising: receiving an interest packet; checking whether or not the interest packet includes a forwarding hint; checking, when the interest packet includes the forwarding hint, whether or not the forwarding hint includes a specific keyword; generating, when the forwarding hint includes the specific keyword, a VRF ID by extracting a VRF name from a name of the interest packet; selecting an FIB by using the generated VRF ID; executing a lookup for the FIB by using an interest name extracted from the interest packet; determining an output port by using the lookup; and transmitting the interest packet to the output port.

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: The present invention relates generally to a network system. Particularly, the present invention relates to a networking method of performing functional data processing in a data-centric network system in which both a pull mode and a push mode are supported. In a data networking method in a data-centric network system of the present invention, a message containing context meta information is received, the received context meta information is analyzed, and from the result from the analysis, filtering for each function element used in a context filtering table (CFT) is performed. Also, function processing specified for a content including the filtered function element is performed.

Abstract: Provided are a method of generating a block chain and an apparatus and method for generating a block. The method of generating a block performed by a node in a block chain network includes receiving a first block from a first node, connecting the received first block to a block chain, determining whether the current node is qualified to generate a second block, which has the first block connected to the block chain as a parent block, generating a second block when the current node is qualified to generate a second block, and transmitting the generated second block to nodes other than the current node. Therefore, it is possible to prevent the waste of energy caused by all nodes performing proof of work for block generation.
