The difference between 4g industrial router and 4g industrial switch

1.Industrial 4g router and 4g switch Description

Industrial 4G router is a network device responsible for path finding. It provides users with communication by finding the least communication from multiple paths in the interconnection network. Industrial 4G router has two typical functions: data channel function and control function. The functions of data channel include forwarding decision, backplane forwarding and output link scheduling, etc. The control function is usually implemented by software, including information exchange, system configuration and system management between the router and the neighboring industry 4G router. Industrial 4G routers are used to connect multiple logically separate networks. The industrial 4G router USES the routing table to select the path for data transmission. The routing table contains the list of network addresses and the distance between each address. The industrial 4G router USES the routing table to find the correct path of the packet from the current location to the destination address. The industrial 4G router USES the least time algorithm or the optimal path algorithm to adjust the path of information transmission. If one network path fails or becomes blocked, the industrial 4G router can choose another path to ensure the normal transmission of information. Industrial 4G routers can convert data formats and become necessary devices for network interconnection between different protocols.

Industrial switch is a device that expands the network and provides more connection ports for the sub-network to connect more computers. With the development of the communications industry and the advancement of the informatization of the national economy, the network exchange market has been rising steadily. It features high cost ratio, high flexibility, relatively simple and easy to implement. Therefore, Ethernet technology has become the most important LAN networking technology, network switch has become the most popular switch. The switch can be recognized based on MAC address, and can complete the function of packaging and forwarding packet network equipment. An industrial switch can “learn” the MAC address and store it in the internal address table, enabling the data frame to go directly from the source address to the destination address by establishing a temporary switching path between the originator of the data frame and the target receiver. If the network utilization is over 40% and the collision rate is over 10%, the industrial switch can help you solve a few problems. Industrial switches with 100Mbps fast Ethernet and 10Mbps Ethernet ports can run in full duplex mode and can establish dedicated 20Mbps to 200Mbps connections.

2.The difference between industrial 4g router and 4g switch

(1)different industrial switches based on different objects for data forwarding use physical address or MAC address to determine the destination address for data forwarding. Industrial 4G routers, on the other hand, use the ID Numbers (i.e. IP addresses) of different networks to determine the addresses for data forwarding. IP addresses are implemented in software that describe the network on which the device is located, and sometimes these third-tier addresses are also known as protocol addresses or network addresses. MAC addresses are typically hardware-owned, assigned by network card manufacturers, and have been solidified into network CARDS, which are generally immutable. IP addresses are usually assigned automatically by the network administrator or the system.

(2) traditional industrial switches can only divide the conflict domain and cannot divide the broadcast domain. Industrial 4G routers can segment broadcast domains. A network segment connected by an industrial switch still belongs to the same broadcast domain, and broadcast packets are spread across all network segments connected by an industrial switch, in some cases leading to communications advocacy and security vulnerabilities. Network segments connected to industrial 4G routers are assigned different broadcast domains, and broadcast data does not pass through industrial 4G routers.

Although the industrial switch above the third layer has VLAN function and can divide the broadcast domain, the communication between sub-broadcast domains is not possible, and the communication between them still needs the industrial 4G router.

(3) industrial 4G routers provide firewall services, which only forward packets of specific addresses, do not transmit packets that do not support routing protocol, and the transmission of target network packets for knowledge, thus preventing broadcast storms.
