What is an industrial router?
An industrial router is a device that analyzes the content of packets traveling within one network or another. An industrial router, which is a physical or virtual device that transfers information between two or more packet-switched computer networks, determines whether the source and destination are on the same network. Check the packet destination Internet Protocol address (IP address) given by the industrial router, calculate the best way to reach the destination, and forward it accordingly.

What is a switch?
The concept of Baidu Encyclopedia is that a switch is a network device used for electrical (optical) signal forwarding. It can provide an exclusive electrical signal path for any two network nodes of the access switch. The most common switches are Ethernet switches. Switches work on the second layer of the OSI reference model, the data link layer. The switch has a high-bandwidth back bus and internal switch fabric for data transfer between multiple port pairs at the same time.
The difference between industrial routers and switches
Different appearance
The main difference between the two is the port. Usually, industrial routers have limited WAN/LAN ports, while switches are mainly used to expand the network and access more networked terminal devices. Therefore, there are more LAN ports, ranging from 8 to 16 ports. . There are even 24-port or 48-port switches on the market.
In addition, the industrial router is connected to the Internet through the cellular network and reflects the wifi signal. It is necessary to expand the coverage of the signal. The antenna of the industrial router has a 5dbi full-frequency rod antenna, and the WIFI adopts a 3dbi high-gain antenna. You can also choose a full-frequency rod antenna for signal external connection, and the signal is more stable. The Ethernet switch is wired to the network and does not need to be used with an
antenna.

Different functions (different application scenarios)
Industrial router: used for indirect network, can connect different networks
Ethernet switch: expand LAN access points and allow more terminals to achieve networking
As mentioned above, industrial routers are networked through a cellular network and can access terminal devices through a wifi wireless network. Therefore, industrial routers are commonly used in projects such as outdoor parking lots, smart water conservancies, industrial oil fields, underground monitoring, on-site monitoring of pollution sources, and wireless video surveillance for security.
The industrial switch is connected to the network through a wired network, and the common one is an Ethernet switch. Therefore, this device is usually used in indoor projects where wiring is convenient. For example, unattended computer rooms, building distribution boxes, and other application scenarios.
Different network processing
Different distribution data
Industrial router: can automatically assign IP and virtual account for LAN
Ethernet switch: just used to distribute network data.
Different processing agreements
Industrial router: The network layer supports the “TCP/IP” protocol and handles IP address addressing
Ethernet switch: just used to distribute network data.
Different support agreements
Industrial router: The network layer supports the “TCP/IP” protocol and handles IP address addressing
Ethernet switch: Addressed by “MAC” address at the relay layer.
Is the IP unified?
Industrial router: The network layer supports the “TCP/IP” protocol and handles IP address addressing
Ethernet switch: Addressed by “MAC” address at the relay layer.
Firewall function
A firewall is a relatively isolated protection and balance between internal and external networks and is used to protect user data and information security technology.
Industrial routers: support firewalls to ensure the safe passage of data.
The ethernet switch does not support the firewall function.
