Editor to share with you about the role of routers in the local area network, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article. Let's learn about it!

The router in the local area network is used to select the network path. A router is a hardware device that connects two or more networks and acts as a gateway between networks. it is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit it.

The function of the router in the LAN is to choose the network path.

A router is a hardware device that connects two or more networks and acts as a gateway between networks. it is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit it. It can understand different protocols, such as the Ethernet protocol used by a local area network and the TCP/IP protocol used by the Internet.

In this way, the router can analyze the destination addresses of packets from different types of networks, convert the addresses of non-TCP/IP networks into TCP/IP addresses, or vice versa, and then send each packet to the designated location according to the selected routing algorithm. So routers can connect non-TCP/ IP networks to the Internet.

The function of a router is to transfer data between different subnets. The specific functions are as follows:

(1) realize the interconnection of IP, TCP, UDP, ICMP and other networks.

(2) deal with the data. Sending and receiving data packets has the functions of packet filtering, multiplexing, encryption, compression and protective wall.

(3) the next transmission destination of the packet is selected according to the information of the routing table.

(4) exchanging topology information between external gateway protocols and other autonomous domains.

(5) realize the functions of network management and system support.

The above is all the contents of the article "what is the role of routers in the LAN"? thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
