A communication gateway is a communication agent device containing rich hardware communication

interfaces and communication protocols. Its features include:

Rich hardware interface and communication protocol: The hardware interface and communication protocol of the

communication gateway can be customized and extended on demand, which makes it able to access almost any hardware device with a communication interface.
Easy access to the Internet: Using a communication gateway can make it easier for hardware devices to access

the Internet. It only needs to provide a set of standard communication protocols and communication interfaces for the Internet, without any changes to the underlying devices.
Reduce server pressure: The use of the communication gateway can reduce the number of IP addresses and ports

occupied by the cloud server, and it can also manage the communication gateway to achieve unified

authorization operations of the underlying devices, such as security and encryption.

Protocol layer and hardware interface abstraction layer: The communication gateway contains the protocol layer and

hardware interface abstraction layer, which are responsible for dealing with the communication protocol and

hardware interface respectively, and enhance the portability and scalability of the software.
Communication gateways play an important role in a network, especially when different networks or systems need

to be connected together. It can not only convert different communication protocols and data formats, but also

adapt to different architectures, so that different systems can communicate smoothly.

In addition, the communication gateway can also be used for WAN interconnection and LAN interconnection, and

it can be used as a gateway device or a router device. In the home network, the common communication

gateway device is the home router, which is responsible for connecting the devices inside the home with the external network.
