Gateway, we all know, from one room to another room, must go through a door. Similarly, sending a message from one network to another must pass through a "gateway", which is gateways. The gateway, as its name suggests, is a "gateway" to a network connected to another network. According to different classification criteria, there are many kinds of gateways. The gateway in the TCP/IP protocol is the most commonly used, where we speak of "gateways" that
