An example of a WAN, what is a WAN?

Ethernetand Wi-FiWireless network (Wi-Fi) are two of the most commonly used technologies in local area networks today.

With the expansion of the Internet around the world, the Chinese Internet.

With rapid development, the number of ISPs in China is increasing, and the services provided are also constantly enriched. However, for China's Internet services to flourish, more and more Internet service providers are needed.

To provide rich services, ISPs also need to continue to expand the service market and adopt flexible operating models.

Find your own way to monetize.

Continuously improve their independent innovation capabilities and enhance their core competitiveness. This paper studies the operating model of ISPs in China, and analyzes the different needs of different business types for ISP operating models.

Application in everyday life:

Wireless LAN.

There are many implementation protocols, and the most widely used is Wi-Fi, which only needs a router to achieve a wireless LAN for all devices with wireless functions, which is very convenient and flexible. Most of today's wireless LANs are standards-based, and most of the wireless LANs under this standard use radio frequency or 5GHz.

Families generally only need one router to build a small wireless LAN, medium-sized enterprises can build a medium-sized wireless LAN covering the entire enterprise through multiple routers and switches, and large enterprises need to build a powerful large-scale wireless LAN with wide coverage through some centralized wireless controllers.

A wide area network (WAN) is also known as a long haul network. It usually spans a large physical range, covering a range of tens to thousands of kilometers, and it can connect multiple cities or countries, or across several continents, and can provide long-distance communication, forming an international long-distance network.

The WAN port rate is to set the speed at which the WAN port of the router works, and improper setting will cause the network speed to decrease.

Set the WAN port rate.

1.Start the computer, connect the router to the power supply, open the browser, and enter the router management address.

2.Enter the router management password to log in to the router.

3.On the navigation menu in the router management page, select Advanced Settings - WAN Port Rate Control

By default, the port rate is "auto-negotiated".

5.At some point, auto-negotiation mode will cause the router to use the slowest mode, such as "10m half-duplex mode", which will slow down the network speed if your bandwidth is greater than 10m.

6.Therefore, it is recommended that you set the WAN port rate of the router to "100M full-duplex mode".

This way the speed of the router is the fastest.

7.Select the WAN port rate and click OK.

Then restart the router, effective immediately.

A WAN is composed of many switches, and the switches are connected by point-to-point lines, and almost all point-to-point communication methods can be used to establish a wide area network, including leased lines, fiber optics, microwaves, and satellite channels. A WAN switch is actually a computer with processors and input and output devices for sending and receiving data packets.

In general, the data transmission rate of WAN is higher than that of LAN, but the propagation delay of the signal is much greater than that of LAN. The typical rate of WAN is from 56Kbps to 155Mbps, and there are already WANs with 622Mbps, Gbps or even higher; The propagation delay can range from a few milliseconds to several hundred milliseconds (when using satellite channels).

Adapt to the requirements of large-capacity and bursty communication;

Adapt to the requirements of integrated business services;

Open device interfaces and standardized protocols;

Complete communication services and network management.

Summary. A Wide Area Network (WAN) is a cross-regional data communication network, usually involving a country or region. A WAN usually consists of two or more local area networks.

Computers often use equipment provided by telecom operators as a platform for information transmission, for example through public networks, such as ** networks, connected to wide area networks, and can also be connected through dedicated lines or satellites. The Internet is currently the largest wide area network. Compared with the OSI (Open System Interconnect) reference model, WAN technology is mainly located at the bottom three levels, namely:

Physical, data link, and network layers.

We know that LAN is a network connection in a small area, and WAN is the network connection between the entire Nianxiao Internet, WAN and LAN have different application ranges, and the functions are also different. What are the steps to build a WAN?

You've done a great job! Can you elaborate on that?

A Wide Area Network (WAN) is a cross-regional data communication network, usually involving a country or region. A WAN usually consists of two or more local area networks. Computers often use equipment provided by telecom operators as a platform for information transmission, such as through public networks, such as ** networks, connected to the wide area network, and can also be connected through special lines or satellites.

The Internet is currently the largest wide area network. According to the OSI (Open System Interconnect) reference model, WAN technology is mainly located at three levels: the physical layer, the hidden data link layer, and the network layer.

1. Wide Area Network (English: Wide Area Network, abbreviated as WAN), also known as Wide Area Network, Extranet, Public Network. It is a remote network that connects computer communication in different regions, either a local area network or a metropolitan area network.

It usually spans a large physical range, covering a range of tens of kilometers to thousands of kilometers, it can connect multiple regions, cities and countries, or across several halls and continents and can provide long-distance communication, forming an international long-distance network. A WAN is not the same as the Internet.

2. When the distance between the hub and the hub is exceeded in an area, it must be connected through a router, which is called a wide area network. If there are branches in the north, middle, and south, or even overseas branches, these branches are connected in the form of private lines, which is called "WAN".

3. The sending medium of the WAN is mainly the use of ** lines or optical fibers, which are connected between enterprises by ISP operators, and these lines are the lines buried under the road in advance by ISP operators, because the project is huge, maintenance is not easy, and the bandwidth can be guaranteed, so it will be more expensive in cost.

4. The Internet is generally referred to as a kind of public WAN, and the cost of the public WAN will be lower, which is a cheaper online environment, but compared with the WAN, there is no way to manage the bandwidth, and the public network system can not guarantee the bandwidth of any disadvantages.
