The technology used in shielding router-type firewalls is based on application gateway technology.

Gateway, also known as Internet connector. Gateway implements network interconnection at the transport layer and is the most complex network interconnection device. It is used for network interconnection between two or more high-level protocols with different protocols. The structure of a gateway is similar to a router device, except for the interconnection layer. A gateway can be used for both WAN interconnection and LAN interconnection. It is a computer system or device that plays the important role of protocol conversion.

zigbee

The wireless sensor network gateway node is zigbee, the control center of the wireless sensor network, which can actively scan all sensor nodes within its coverage and manage the complete routing table of the entire wireless monitoring network. Receive data from other nodes, perform correction, fusion and other processing on the data, send it to the remote monitoring center through network infrastructure such as GPRS or Ethernet, and process the instructions issued by the monitoring center accordingly. Gateway nodes usually connect two or more independent networks and need to convert different protocols above the transport layer. Therefore, they have high requirements on the data transmission and computing capabilities of the central controller.

Application gateway is an inter-network device that connects one network to another and provides specific applications. The application gateway must be able to implement the corresponding application protocol. The application gateway can be seen as an intermediate process running between the client that requires specific services and the server that provides the required services. In this type of process, the application gateway plays the role of a server from the user side, and is a client from the server side.
