What are the basic functions of a router? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The basic functions of the router are: 1, network interconnection; 2, data processing; 3, network management. A router is a hardware device that connects two or more networks and acts as a gateway between networks. Its function is to transfer data between different subnets.

The basic functions of a router are:

1. Network interconnection

Routers support a variety of local area network and wide area network interfaces, which are mainly used to interconnect local area networks and wide area networks to communicate with each other.

2. Data processing

Provides functions including packet filtering, packet forwarding, priority, reuse, encryption, compression and firewall

3. Network management

Routers provide functions including router configuration management, performance management, fault-tolerant management and flow control.

Related introduction:

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 answers to the questions about the basic functions of the router are shared here. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
