    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: Disclosed are a method for delivering emergency traffic in a SDN based network and an apparatus performing the same. A method for delivering emergency traffic, performed in a controller, may comprise generating an emergency code for delivering the emergency traffic when an emergency state corresponding to a predefined type occurs; transmitting the emergency code to a first OpenFlow switch connected to a transmitting terminal transmitting the emergency traffic; and transmitting a message directing an update of the emergency code to at least one OpenFlow switch included in a forwarding path of the emergency traffic. Therefore, when an emergency state occurs in a network, emergency traffic corresponding to the emergency state may be delivered efficiently, and stabilities of network management and service qualities may be guaranteed accordingly.

    Abstract translation: 公开了一种用于在基于SDN的网络中传送紧急业务的方法和执行其的装置。 一种用于在控制器中执行的紧急通信的方法可以包括：当发生与预定类型相对应的紧急状态时，生成用于传送紧急业务的紧急代码; 将紧急代码发送到连接到发送紧急业务的发送终端的第一OpenFlow交换机; 以及将紧急代码的更新指示给包括在所述紧急业务的转发路径中的至少一个OpenFlow交换机的消息。 因此，当网络发生紧急状态时，可以有效地发送对应于紧急状态的紧急通信，可以相应地保证网络管理和服务质量的稳定性。

    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 is a system for a secret sharing authentication. The system may include a secret sharing information management server, a client device, and a network device. The secret sharing information management server may store and manage an authentication key capable of being used for secret sharing authentication, by dividing the authentication key into a first secret sharing key shard and a second secret sharing key shard, and allocate the first and second secret sharing key shards. The client device may receive the first secret sharing key shard from the secret sharing information management server and construct an interest packet by using the first secret sharing key shards. The network device may receive the second secret sharing key shard from the secret sharing information management server, and process the interest packet received from the client device on the basis of an ICN(Information Centric Networking) method by performing secret sharing authentication using the second secret sharing key shard and the first secret sharing key shard comprised in the interest packet.
