An industrial switch is a network device that identifies data packets based on MAC addresses and performs packet encapsulation and forwarding. Industrial switches can "learn" MAC addresses and store them in an internal address table. By establishing a temporary switching path between the sender and receiver of a data frame, they allow data frames to travel directly from the source address to the destination address. If network utilization exceeds 40% and the collision rate is greater than 10%, an industrial switch can help resolve some issues. Industrial switches with 100Mbps Fast Ethernet and 10Mbps Ethernet ports can operate in full-duplex mode and establish dedicated 20Mbps to 200Mbps connections.
Industrial 4G routers utilize routing protocols to obtain network information and employ routing algorithms and criteria based on a "routing matrix" to select the optimal path. According to the OSI reference model, an industrial 4G router is a network layer system. Industrial 4G routers are categorized into single-protocol and multi-protocol types.
The Internet is composed of various networks, and industrial 4G routers are a very important component of it. There are countless industrial 4G routers on the Internet. For an Intranet to be integrated into the Internet and provide Internet services, an industrial 4G router is an essential component, and the equipment of an industrial 4G router is relatively complex.
Similarities
(1) "Switching" is a word with a broad meaning. When it is used to describe a Layer 2 device in a data network, it actually refers to a bridging device; while when it is used to describe a Layer 3 device in a data network, it refers to a routing device. That is, industrial switches and industrial 4G routers can both be used to switch network devices, only the network layers they switch are different.
(2) Able to access the internet. They are all used to extend the network.
