What problems can the load balancing system in the Internet access system solve?

The following problems can be solved through load balancing: solve the problem of network congestion, and the service is provided nearby. Provide users with better access quality. Improve the response speed of the server. Improve the efficiency of the use of servers and other resources.

It is suitable for solving the problem of Internet IP address tension and not wanting the outside of the network to know the internal network structure, etc.

Flow control: F5 load balancing supports traffic control based on IP, URL and other dimensions, which can limit the traffic and speed according to actual needs to ensure the stability and security of the system.

Load balancing in WLAN is composed of multiple APs.A mobile terminal provides access service system. Each AP uses network information for site management in order to make full use of the existing network resources and reduce network blockage.

Balancing the load can evenly distribute customer requests to the server array, thus providing quick access to important data and solving a large number of concurrent access service problems.

The wireless access method of the Internet terminal system is ()

GSM access technology, etc. In addition, there are CDMA access technology, GPRS access technology, CDPD access technology, fixed wireless broadband access technology, DBS satellite access technology and Bluetooth technology, etc.

Wired connection: Connect the router to the computer or other wired devices through the network cable. In this way, you need to find the WAN port and LAN port on the router, insert one end of the network cable into the WAN port, and insert the other end into the network card interface of the computer or other wired devices. GPRS/CDMA, 3G and WLAND belong to wireless access to the Internet.

ISDN Internet access method ISDN is InThe abbreviation of tegrated Service Digital Network is an international standard for digital telephone networks, that is, narrowband integrated service digital network, commonly known as "first-line communication", which also uses existing telephone lines to access Intemet.

Wi-Fi access: This is the most common wireless access method. Users only need to connect to the available Wi-Fi network in the network settings of the device to access the Internet.

There are several ways to access the Internet: connect the computer to the Internet with the help of modem, ISDN, x.25 and other communication methods. The broadband of this method is not high. It was often used a few years ago, and now it is slowly withdrawing, such as China's 16300, mobile company's GPRS, etc.

Take the Internet as the center and describe in detail the composition of modern communication network systems?

1. Hardware equipment: The hardware equipment in the computer network includes computers, servers, routers, switches, hubs, network cards, etc. These devices can be connected to each other to form a network topology, so that data can be transmitted in the network.

2. The network segment separated by the bridge still belongs to the same LAN. The network address is the same, but the segment address is different. (7) Router Router is a connection device used on the Internet. It can connect two networks together to form a larger network.

3. In terms of hardware, the communication network is mainly composed of terminal equipment, switching equipment, transmission system, etc.

4. The Internet is composed of a network, which is composed of nodes and connections, indicating that many objects are interconnected. Expanding knowledge: The increasing innovation of science and technology is changing our lives, but the transformation of the Internet has directly changed and affected people's lifestyle.

5. The data communication system is mainly composed of communication control processor, transmission medium and network connection equipment. X communication control processor The communication control processor is mainly responsible for the information transmission control of the host and the network. Its main functions are: line transmission control, error detection and recovery, code conversion, and data frame assembly and disassembly.

6. Division of the Internet Although the topology of the Internet is very complex and geographically covers the world, from the perspective of its working method, it can be divided into the following two parts: the edge part is composed of all hosts connected to the Internet.
