Building a decentralized network

There are two kinds of network construction:

1, simple LAN construction. A wireless router, the client has network card or wireless network card. Generally, wireless routing integrates route switching, network address translation, DHCP and wireless, and the interface is intuitive and simple. It is recommended to use router plus switch or hub for small LAN

connect the network incoming line to the WAN port of the router. If you want to access the Internet, set up the WAN port. The LAN port of the router is connected to the client computer or switch (a switch only connects one network cable to the LAN port of the router to avoid the loop). The switch is not configured here and is only used as an expansion interface

turn on the wireless function and DHCP service of the wireless router, and set up the network segment of your network. Such a simple LAN can be built successfully and can be used (at least 200 client users can use it). Because the router has DHCP service, there is no need to set the client separately

2. The network with complex points generally has LAN across buildings or regions, or LAN with large number of users and complex network situation. First of all, each building or floor according to the user's situation, the client network cable or wireless connection to the network management access switch, the access switch is divided into VLAN, so a simple LAN is built

then connect the access devices of relevant floors or buildings with convergence switch and convergence connection medium (optical fiber, network cable), divide the corresponding network segments on the convergence switch devices and assign them to each access switch, and complete the relevant routing rules, so that a larger local area network can be completed

if the converging switch can enable the DHCP service, start and set up the relevant DHCP service, if not, you need to set up a DHCP server on the computer and point to the DHCP service on the converging switch as the IP of the computer (without DHCP service, you need to manually set the IP of each client)

when there is a cross regional LAN, we also need to connect VPN devices on the converging switching devices to achieve cross regional connection; If your network still has Internet access, then the aggregation device should also be connected to the firewall device (or router) to achieve external communication (mainly using the network address translation function)

if the network is large enough and there are multiple convergence devices, a core switch should be added to connect with the convergence devices, and the relevant routes on the core switch should be set; If your network usage is complex, make effective use of the relevant access control and routing functions on all levels of switching equipment to plan and limit, so as to achieve the mutual access limit and application limit

precautions for building a network:

1. The speed of downloading things from the website must be fast

2. There should be no more than 6 options for web page setting

4. Web design standards should be based on the information needs of visitors

5. The website should be designed to facilitate the interaction between visitors and the website or service center
