The Internet cafe network system needs to have a high bandwidth and support a large amount of data transmission. Therefore, Internet cafes have higher requirements for network hardware. When designing the Internet cafe network, it is necessary to ensure a high-quality network transmission speed, and also consider future network upgrades and maintenance. Next, Walsun will introduce network equipment solutions for Internet cafes.
First of all, in the selection of network equipment, we need to choose a high-performance diskless server. In terms of options, we can choose a motherboard that supports dual CPUs, 512G memory, and Intel E5 architecture CPUs.
Then, what we need to do is to choose two H3C full 10G switches to build a 10G network, enjoy games, 4k movies and other service experience. The transmission carrier of the server and the switch can use Walsun’s 10G optical modules with OM3 multi-mode fiber patch cords to achieve link transmission within 300 meters. The connection between the switch and the computer uses a Cat5e network cable. The network diagram of the Internet cafe is as follows:
The advantage of using optical fiber for cabling is that it has scalability so that more devices can be accessed in the future, and the optical fiber has good anti-interference performance during high-speed transmission and can adapt to complex electromagnetic interference. Compared with copper cabling, optical fiber is better in terms of stability.
In addition, virus intrusion and illegal attacks are the biggest security risks of Internet cafes. For security considerations, firewall devices can be connected. However, because the price of firewalls is relatively expensive, it is recommended to consider again when funds allow.
In order to ensure the stability of the Internet cafe network, when selecting network equipment such as switches and routers, it is necessary to choose equipment that can effectively prevent APR spoofing, IP scanning, DDOS and other attacks.
