Preferred choice for Internet cafes: AR18 Huawei Internet cafe Router

In the industry, Huawei's Internet cafe routers are perfect in terms of Preventing ARP attacks, dual-line policies, traffic control, and connection limit and ranking. As an internet cafe owner, please refer to the comparison.

The development of the Internet cafe industry has been in China since year 78. With the rapid development of Internet technologies and users, Internet cafe operators are also facing an environment of rapid changes. From the early ISDN to the data leased line, so that ADSL and optical fiber access, the speed of connecting Internet cafes is getting faster and faster. The improvement of Internet cafe network environment also brings about many problems, such as the flood of ARP viruses and the use of P2P software to occupy a large amount of bandwidth, which makes the Internet cafe owners have a headache. To address these problems, Huawei 3Com launched the AR18 series of Huawei Internet cafe routers. Including AR18-21, AR18-22, AR18-22-8, AR18-23-1 and AR18-63-1, the five equipment has a wide range of suitable for the use of the characteristics of Internet cafes, with the amount of machine is also very large, in between-sets, is the best choice for medium-sized Internet cafes. Next we will give a brief introduction to the series of routers for common functions of Internet cafes.

1. Prevent ARP attacks

In Internet cafes, IP + MAC binding and free ARP sending can effectively prevent ARP viruses. In addition, we recommend that you install Anti-ARP Sniffer software on each server.
1. IP + MAC binding. On the web interface of the AR18 router, you can easily bind all the PCs in the LAN through the "curing ARP" operation.
2. Send free ARP: on the "ARP attack prevention" page of The AR18 router, enable the anti-attack function and set the correct gateway ARP information to be sent every second.
3. install Anti-ARP Sniffer software on each PC: Select "automatic protection"-"Automatic startup"

Ii. China Netcom and China Telecom dual-Line Policy Routing

Currently, most Internet cafes are China Netcom and China Telecom lines. We hope that servers accessing China Telecom in Internet cafes can access China Telecom lines, and servers accessing China Netcom can access China Netcom lines to ensure the fastest access speed. A Huawei Internet cafe router imports the IP route table of China Netcom to implement the policy routing function.

3. Traffic Control IP address speed limit)

In Internet cafes, P2P software is often used for download, and the download speed and traffic are extremely high. Internet cafes often only have 10 Mbps of Internet bandwidth, and several others use tools such as BT for download, all the bandwidth is used up, and other users cannot access the Internet normally. Therefore, we need to limit the speed of computers in the network. The AR18 router can limit the traffic of a single PC and each PC in the entire network segment on the web interface.

Iv. Connection limit and ranking

Many Internet users in Internet cafes use multi-threaded download software to download, which will create a large number of Nat connections, especially download tools such as thunder. One PC machine can have more than 600 connections, this is too load-intensive for routers, which severely affects the performance of routers in Internet cafes of Huawei. Therefore, you need to limit the number of connections per PC. You can also dynamically view the current number of connections and quickly find the PC to download. The AR18 router can limit the number of connections between a single PC and each PC in the entire network segment on the web interface, and can also view the number of connections ranking of hosts in the LAN.
