The difference between industrial routers and industrial switches

The difference between industrial routers and industrial switches:

A router, also known as a selector, is a device that realizes interconnection at the network layer. It is more complex than a bridge and also has more flexibility. Routers have stronger interconnection capabilities of heterogeneous networks, and the connection objects include local area networks and wide area networks. The router has two typical functions, namely the data channel function and the control function. Data channel functions include forwarding decision, backplane forwarding and output link scheduling, etc., which are generally completed by specific hardware; control functions are generally implemented by software, including information exchange with adjacent routers, system configuration, system management, etc. .

A switch is a network device that can be identified based on MAC (hardware address of the network card) and can complete the function of encapsulating and forwarding data packets. The current switches are divided into: Layer 2 switches, Layer 3 switches or higher-layer switches. Layer 3 switches can also have routing functions, and the forwarding rate is faster than that of low-end routers. Its main features are: one routing, multiple forwarding.

Switches are generally used for LAN-WAN connections. Switches belong to bridges and are devices at the data link layer. Some switches can also implement Layer 3 switching. Industrial-grade 4G routers are used for the connection between WAN and WAN, which can solve the forwarding of packets between opposite networks and act on the network layer. They just accept incoming packets from one line and forward them to the other line. The two lines may belong to different networks and use different protocols. In comparison, the functions of industrial-grade 4G routers are stronger than switches, but the speed is relatively slow and expensive. The third-layer switches have both wire-speed packet forwarding capabilities of switches and good control functions of industrial-grade 4G routers. Therefore it is widely used.
