What are the functions of the router and what are the main functions of the router?

First, network interconnection, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

second, data processing, which provides functions including packet filtering, packing**, priority, multiplexing, encryption, compression, and firewall;

Third, network management, routers provide functions including configuration management, performance management, fault tolerance management, and traffic control.

In order to complete the work of "routing", the relevant data of various transmission paths is saved in the router, and the routing table is used for route selection. The route table stores the flag information of the subnet, the number of routers on the network, and the name of the next router. The routing table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host.

There are two concepts involved in the name of an address in a router: a static routing table and a dynamic routing table. The fixed routing table set by the system administrator in advance is called static routing table, which is generally pre-set according to the configuration of the network when the system is installed, and it will not change with the change of the network structure in the future.

A dynamic routing table is a routing table that is automatically adjusted by the router according to the operation of the network system. Based on the functions provided by the routing protocol, the router automatically learns and memorizes network conditions, and automatically calculates the best path for data transmission when needed.

The normal situation is to realize that several computers use the same broadband at the same time. That is, a broadband brancher.

Routing features. Signal amplification function.

The router has the following main functions:

Packets sent to remote network segments are carried between networks, which plays the role of **.

Select the most reasonable route to guide the communication. In order to achieve this function, the router needs to follow a certain routing protocol and find the routing table. Each router in the network dynamically updates the routing table it maintains according to this rule in order to maintain valid routing information.

In the process of ** packets, in order to facilitate the transmission of packets between networks, the router decomposes large data packets into appropriate size packets according to predetermined rules, and then wraps the decomposed data packets into the original form after arriving at the destination.

A multi-protocol router can connect network segments that use different communication protocols as a platform for communication connections between network segments with different communication protocols.

The main task of a router is to direct communication to the destination network and then to a specific node address. The latter function is done through network address decomposition.

Dynamic rate limiting: A dynamic rate limiting router can calculate the bandwidth required by each user in real time, accurately analyze the user's Internet type, and reasonably allocate the bandwidth to achieve on-demand allocation.

The basic functions of the router are as follows:

First, network interconnection, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

second, data processing, which provides functions including packet filtering, packing**, priority, multiplexing, encryption, compression, and firewall;

Third, network management: routers provide functions including router configuration management, performance management, fault tolerance management, and traffic control.

Extended Materials. Router is one of the indispensable network equipment in the Internet, a router is a network device that connects multiple networks or network segments, it can "translate" the data information between different networks or network segments, so that they can "read" each other's data, so as to form a larger network. There are two typical functions of a router, namely the data channel function and the control function.

The data channel functions include ** decision, backplane ** and output link scheduling, etc., which are generally completed by specific hardware; Control functions are generally implemented by software, including information exchange with neighboring routers, system configuration, system management, etc.

To explain the concept of a router, first introduce what a route is. The so-called "routing" refers to the behavior and action of transmitting data from one place to another, and the router is the machine that performs this behavior and action, and the English name is router.

The router has two functions, one is to connect different networks, and the other is to choose the route to transmit information. Choosing a smooth and fast shortcut can greatly improve the communication speed, reduce the communication load of the network system, save the network system resources, and improve the smooth rate of the network system, so that the network system can play a greater role. A router can allow several computers to be connected at the same time and have a LAN connection when there is no network or when there is a network.

The basic functions of the router are as follows:

First, network interconnection, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

Second, data processing: it provides functions including group filtering, group filtering, priority trouble, multiplexing, encryption, compression, and firewall;

Third, network management: routers provide functions including router configuration management, performance management, fault tolerance management, and traffic control.

The main functions of the router: 1. Connect to the Internet, so that the local LAN and the Internet are connected. That is, the Internet function!

2. Increase the number of machines, the size of the number of machines is determined by the hardware attributes and functions of the router itself, which is what we call the switch function!

3. The function of adjusting the network rate and managing the behavior of the client! It is to optimize the network speed, allocate according to demand, and control the individuality.

4. Firewall function (some models).

5. AP function (wireless router), that is, to set up WiFi.

So much to think of for the time being!

The functions of the router include network interconnection, data processing, network management, isolation of subnets, suppression of broadcast storms, maintenance of routing tables, etc.

1. Network interconnection.

The router supports a variety of LAN and WAN interfaces, and is mainly used to interconnect LAN and WAN to achieve communication between different networks.

2. Data processing.

Provides features including packet filtering, packing**, prioritization, multiplexing, encryption, compression, and firewall.

3. World Bank network management.

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

4. Isolate the subnet to suppress broadcast storms.

Broadcast packets in any subnet will be cut off at the router because the router does not broadcast the message search packet.

5. Maintain the routing table.

and exchange routing information with other routers, which is the basis of data packets at the network layer.
