Abstract: A method and an apparatus for constructing a multi-stage hash table are disclosed. According to an embodiment of a present disclosure, a method for constructing a multi-stage hash table includes attempting to add management table information to a first management table and attempting to add hash table information to a first hash table. The method also includes determining whether second management table information having the same hash value as a hash value included in first management table information is present in a k-th management table. The method also includes attempting to add table information to the k-th management table and a k-th hash table or to a (k+1)-th management table and a (k+1)-th hash table based on the determination result.

Abstract: Disclosed herein are a packet forwarding method and a node in a content centric network. The node constituting a content centric network may perform packet forwarding by including: a plurality of interfaces configured to receive and transmit an interest packet and a data packet for a plurality of remote nodes, a pending interest table (PIT) for storing information on a local interest packet, among non-responded interest packets, of which its source network or destination network corresponds to the network in which the corresponding node is located, a tag table for storing information on a transit interest packet group associated with a source network, among non-responded interest packets, of which a source network and a destination network are not the network in which the corresponding node is located, a forwarding information base (FIB) for forwarding an interest packet to a destination node and a processor for selecting the PIT or the tag table, when packet forwarding, according to whether the packet is a local packet or a transit packet, and for performing packet forwarding based on the selected table.

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: An apparatus and method for providing dynamic network programming based on a selective binding segment of segment routing in a communication system is provided. A method by which a first service programmable network (SPN) node operates in a communication system includes: receiving a first packet from a zeroth SPN node; identifying a segment routing header (SRH) of the first packet, the SRH including a segment list; identifying a selective binding segment based on the segment list; requesting a processing result from a network service function (NSF) corresponding to the segment list when the segment list involves the selective binding segment; receiving a color value according to the processing result from the NSF; dynamically selecting a segment list according to the color value; and transmitting a second packet, to which a new SRH including the selected segment list and a new header are added, to a second SPN node.
