    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 is a Quality of Service (QoS) providing method and apparatus in a software-defined networking (SDN) based network, the QoS providing method including receiving a first packet of a predetermined flow, searching for forwarding information corresponding to the packet and QoS rule information corresponding to the packet in a forwarding table and a QoS rule table, respectively, transmitting the packet to a controller if the forwarding information and the QoS rule information do not exist in the forwarding table and the QoS rule table, and generating a flow entry corresponding to the packet in a flow learning table based on forwarding information and QoS rule information that are received from the controller, thereby efficiently providing QoS.

    Abstract translation: 本发明公开了一种基于软件定义网络（SDN）的网络中的服务质量（QoS）提供方法和装置，所述QoS提供方法包括接收预定流量的第一分组，搜索对应于分组的转发信息和QoS规则 如果在转发表和QoS规则表中不存在转发信息和QoS规则信息，则将转发表中的分组对应的信息和QoS规则表分别发送到控制器，并且生成流入口 对应于基于从控制器接收的转发信息和QoS规则信息的流学习表中的分组，由此有效地提供QoS。

    Abstract: Disclosed herein are a method for protecting data for information centric in-network computing and a system using the same. The method includes: preparing, at a computing node, a an encryption key pool that includes a security key for sharing a symmetric key used for encrypting result data according to a user's request and matching information; preparing, at an INC agent receiving the user's request, a synchronization key pool for sharing the security key through the matching information; and creating, by the computing node, a processor for executing output processing of the result data and allocating a security key to the processor based on the matching information of the encryption key pool when a security key exists. The security key is allocated to the computing node which is determined to perform the request in the INC agent.
