Abstract: Disclosed is a network self-diagnosis control device based on a block-chain. The device includes a management policy registering unit configured for registering, in a block-chain gateway, an identification code for each of a plurality of network nodes constituting a target network and a management policy indicating a permission range, an operation verifying unit configured for verifying an operation of a specific network node executed by a specific user through the block-chain gateway, and an operation permission determining unit configured for, when the operation of the specific network node is not registered on the block-chain gateway, self-diagnosing management policies of other network nodes of the same type as the specific network node in the block-chain gateway and for determining whether to permit the operation based on the self-diagnosing result.

Abstract: Disclosed is a software-defined networking device based on service profile learning. The device includes a physical network configuration unit for configuring a physical network via identification of a plurality of physical nodes, a service profile generating unit for analyzing packets respectively communicated from end nodes among the plurality of physical nodes to generate a service profile, a service profile learning unit for learning spatiality and temporality of the packets, and segmenting the plurality of physical nodes into service profile groups based on the learning result, and a software-defined networking unit for configuring a virtual network on a service profile group basis to generate a software-defined network.
