Presently, there is a variety of industrial-grade equipment available on the market. Many people tend to confuse industrial routers and industrial switches. Today, I will give you a brief introduction to the difference between the two in terms of function and working principle.
What are the functions of industrial routers and industrial switches?
Alotcer 5G industrial LTE cat 6 router AR7091 is an industrial IoT gateway developed based on 5G/4G/3G/2G, WIFI, virtual private network and other technologies. The product adopts a high-performance industrial-grade 32-bit communication processor and industrial-grade wireless module, with an embedded operating system as the software support platform, and supports 1 Gigabit Ethernet WAN, 4 Gigabit Ethernet LANs, and 1 RS232/ RS485 (optional) interface and 2.4G/5.8G WIFI interface can connect serial devices, Ethernet devices and WIFI devices at the same time, mainly suitable for places with high network requirements or harsh environments.
Industrial switches are low in cost and complete in grade. It usually has several to dozens of ports. It is actually a multi-port layer-2 network device based on bridge technology, which provides a low-latency, low-overhead path for forwarding data frames from one port to another arbitrary port. In addition, its port rate can be different, and its working mode can also be different, such as providing 10M, 100M bandwidth, providing half-duplex, full-duplex, self-adaptive working mode, etc.
What are the working principle of industrial routers and industrial switches?
An industrial router is a device that supports full Netcom. It can complete data transmission, Internet access, etc. through the operator’s 5G network dial-up network, and can perform interactive transmission. For remote big data, it can also be used as a router to use the WiFi function to complete shared Internet access.
An industrial switch is a machine at the data link layer. When it receives a broadcast frame, it forwards it to all ports except the receiving port. When a unicast frame is received, check its destination address and correspond to its own MAC address table. If there is a destination address, it will be forwarded. If it does not exist, it will be broadcast. If there is no host MAC address and frame address after broadcasting, if the destination MAC address is the same, it will be discarded. If there are hosts with the same address, the MAC address of the host will be automatically added to its MAC address table.
