  • Publication number: 20240137316
    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.

  • Publication number: 20190182029
    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.

  • Publication number: 20080139221
    Abstract: A system for providing an address using a geocoding application programming interface (API) in an open service platform and a method thereof are provided. The system includes an application server which performs an address service and a function of a web server, a location information server which provides location information of a mobile terminal, an address server which provides the address information corresponding to the location information, and a service gateway which accesses the location information server and the address server in order to provide the address information to the application server according to a request of the application server. Since a telecommunication carrier has a location information server and an address server, a gateway and an application server can communicate with each other using a standard geocoding API.
