Many devices and objects have recently been connected to the network using the Internet of Thing technology. In a local area network (LAN) network for small scale, many devices are connected and the complexity of the network topology is greatly increased. Large-scale networks of such small-scale networks are also expanding nationwide. he flow of gathering and spreading data in a concentrated or distributed manner within a large network is being made. This is useful for various industries, financial, telecommunications, military, and power generation facilities in statebased industries use the nationwide Internet network to control and maintain a stream of data that can cope with emergency situations. In a network environment that has such a circumstance, if a critical device (node) or a small range of network (LAN) that is involved in the control, data collection, storage, or data processing is isolated and isolated from the entire network. This paper discusses techniques for isolating critical LANs or Nodes in large networks.
