Node management gateway device, system, and method in power distribution network and grid network

摘要

A distribution network system having a plurality of nodes using a scheme for data-centric objectoriented communication (DDS) effectively manages the frequently occurring connections for each node and the real-time addition or deletion of a node. Each node includes a gateway connected to a Wide Area Network (WAN) and configured to transmit and receive a message using a Real-Time Publish-Subscribe (RTPS) protocol that applies simple tunneling to communicate as if all nodes communicate in a Local Area Network (LAN), and to insert magic information into a header of the message, the inserted magic information including source IP information of the message, destination IP information of the message, and destination User Datagram Protocol (UDP) information of the message.
