Introduction to router functions in Internet cafe operations (1)

At present, most Internet cafes do not fully utilize the power of the router function when using the router, so that the Internet cafe router resources are wasted. There are many reasons why the internet cafe router function cannot be fully used, but the main reason is that the Internet cafe owner and administrator do not know much about the internet cafe router function. In order to allow Internet cafe owners and administrators to better use Internet cafe routers, we have collected some common functions of Internet cafe routers by the itworld network channel, which will be introduced to you.

Common functions

Common functions of routers are defined as common basic and practical functions. They mainly include traffic control, support for internal servers, DHCP, and IEEE802.1X authentication, specifying the computer's Internet access permissions and enabling/disabling the Internet access function at regular intervals. These functions can be very helpful for Internet cafe operations.

Traffic Control

I believe everyone is very familiar with traffic control. Currently, all the dedicated routers for bars have this function. It can allocate network bandwidth. As the number of Internet cafes continues to expand, the corresponding bandwidth is also increasing. If you charge fees based on the previous single mode, for Internet cafes, funds will not be withdrawn. Therefore, we can use the traffic control function to divide the internet cafe charging standards and charge a higher fee for high bandwidth.

Next we take TL-R4000 as an example, a simple design of the basic architecture of Internet cafes. This Internet cafe router provides traffic control. Each of its lanports sets an eight-level bandwidth limit, which is 128 K, 256 K, 512 K, 1 M, 2 M, and 4 M, 8 M, this Internet cafe router has a total of four LAN ports. At present, the network bandwidth connected by Internet cafes is generally 10 MB. We do not consider 8 MB allocation. In fact, most Internet users access the Internet through web pages, playing games, chatting with QQ, etc. We can divide the internet cafe into four zones, which also makes full use of the port of this router. The four zones are VIP, high-speed, normal, and low-speed zones. the VIP area is convenient for Internet users who often access Internet cafes (but most of the game players in this area are here ), the number of computers connected to the following area can be relatively small; the high-speed area can be provided to users who need to download or watch movies online. The number of computers is a little larger than that in the VIP area, in addition, the computer hardware configuration is reduced. Common areas can be used by various users, and the number of computers can also be increased. Low-speed areas can be used by users who browse webpages and chat, in this way, the allocation is reasonable. If the Internet cafe uses a 10 MB network, we recommend that you allocate 4 MB of bandwidth to the VIP area, 2 MB of bandwidth for high speed, 2 MB of bandwidth for general use, and 2 MB of bandwidth for Low Speed areas. Both normal and low-speed zones have a relatively large amount of Internet access, and there are a lot of computers, so they all allocate 2 MB of bandwidth. The number of computers in low-speed areas should be larger than that in normal areas, this will increase internet cafe revenue, while the number of people in the high-speed zone is relatively small, and the number of computers can be smaller. 2 MB bandwidth can be used; the 4 mb vip area can be allocated to netizens who often access the Internet. This is also a good way to increase internet cafe income. In fact, this is a simple idea. Internet cafe users can set it according to their actual needs.

Internal Server features

The internal server function refers to the vro that supports virtual servers. You can set up an online game server in the internal network of an internet cafe and use port ing to enable users to log on to the game server on the Internet and Intranet at the same time. This feature is supported by most routers and does not need to be set.

The internal server function is mainly used to help Internet cafe users establish various types of servers, such as online game servers and movie servers. Internet cafe users only need to set up some software to enable charges, this will bring a considerable revenue to Internet cafe users, so this function is common, but very practical.

DHCP

In some micro-Internet cafes, because the number of computers is small, we can manually allocate IP addresses to achieve network connections, but this is not practical for large and medium-sized Internet cafes with a large number of computers. The DHCP Service can help the internet cafe administrator verify the IP address and other configuration parameters in the internet cafe without checking each host. The DHCP Service does not allow two computers to share one IP address in the network; therefore, this function is of great benefit to Internet cafe planning.

IEEE 802.1X authentication

IEEE 802.1X authentication is the most widely used function in Internet cafes. IEEE 802.1X is a Client/Server-based access control and authentication protocol that can restrict unauthorized users to access the network and support billing management. For Internet cafe operations, is a good function. The routers that support IEEE 802.1X authentication also have built-in IEEE 802.1X clients.
