The working principle of industrial dual card 4g router |
Posted: December 9, 2021 |
The whole network industrial router has multiple ports, which are used to connect multiple IP subnets. The network number of the IP address of each port must be the same as the network number of the connected IP subnet. Different ports are different network numbers and correspond to different IP subnets, so that the hosts in each subnet can send the requested IP packets to the industrial TD-LTE router through the IP address of their own subnet. Text: Before talking about the principle of industrial dual-card routers, let’s briefly talk about what a dual-card router is. A dual-card router is a network device that connects multiple networks or network segments. It can transfer data information between different networks or network segments. Perform "translation" so that they can "read" each other's data to form a larger network. The dual sim 4g router has two main 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 neighboring industrial routers, system configuration, and system management Wait. With the continuous expansion of the scale of computer networks and the rapid development of large-scale Internet networks (such as the Internet), routing technology has gradually become a key part of network technology, and industrial dual-card routers have also become the most important network equipment. The needs of users are driving the development of routing technology and the popularization of industrial-grade dual-card routers. People are no longer satisfied with sharing information only on the local network, but hope to maximize the use of various regions and types of network resources in the world. In the current situation, any computer network with a certain scale (such as enterprise network, campus network, intelligent building, etc.), whether it uses fast Ethernet technology, FDDI technology, or ATM technology, cannot do without industrial routers. , Otherwise it will not be able to operate and manage normally.
