Internet cafes, network management experience, bandwidth management skills to achieve

Contents
The "Flying Fox Network Club" located in the center of Lusong District of Zhuzhou City is a small and medium-sized Internet cafe. Among them, the biggest feature is that even if the attendance rate reaches 100%, there are few phenomena such as card net and poisoning. It is understood that the reason why there is such a good business scene, the network management solution of its interview has played a significant role. Below, we take the Flying Fox Network Club as an example to introduce you to the series of solutions for its application.

I. Introduction of User Background Information

The industry regulations and requirements of Internet cafes are becoming more and more strict. The scale and specialization of Internet cafes are the direction of future market competition. Then, how to make your own Internet cafes on the road of specialization, network bandwidth management is a top priority. Nowadays, Internet cafes often encounter three major problems in bandwidth management: BT, P2P, and video continue to be maliciously downloaded, resulting in more bandwidth is not enough; Netcom Telecom cross-network bottlenecks, causing gamers not to play smoothly; even common The ARP attack has led to a comprehensive poisoning incident in the entire Internet cafe. Solving the above three problems is basically equal to mastering the market opportunities. Your Internet cafes should meet the needs of customers, and naturally become professional.

The "Flying Fox Network Club" located in the center of Lusong District of Zhuzhou City is a small and medium-sized Internet cafe. Among them, the biggest feature is that even if the attendance rate reaches 100%, there are few phenomena such as card net and poisoning. It is understood that the reason why there is such a good business scene, the network management solution of its interview has played a significant role. Below, we take the Flying Fox Network Club as an example to introduce you to the series of solutions for its application.

Second, solutions and important applications

The Flying Fox Network Club now has 420 PCs, 100M telecom fiber for network bandwidth, and Qno's GQF500 Internet cafe dedicated router as a network access device. And using its intelligent QoS, virtual routing, IP two-way binding and other functions, has successfully solved the three major problems most commonly encountered in Internet cafes. Stable, high-quality, smooth network services, coupled with other services and conditions, the Flying Fox network club business is hot, even on weekdays, the attendance rate can reach 100%. ;;

Referring to the success reason, Mr. Feng Jian, the network administrator of the Flying Fox Network Club, introduced the current network access product GQF500 and its application. solution. He said that the intelligent QoS of GQF500 is manifested in the automatic suppression of the outstanding functions of a large number of occupants, and its unique virtual routing technology, which has solved the long-standing cross-network bottleneck of "South Telecom North Netcom". ;;

1, intelligent QoS effectively suppress a large number of accounts with those who continue

According to Mr. Feng Jian, before this, in the face of a large number of upload and download activities generated by large-scale 3D online games, video chat, online video playback, BT and P2P technology applications, it often causes serious network congestion in Internet cafes. . If traditional QoS bandwidth management is adopted, once a large number of downloads eat up bandwidth, you must first find out the IP one by one, and further warn the user for the penalty. This is wasteful, and the customer changes IP and downloads again. It’s hard to prevent it from being repeated. Now, Qno's GQF500 intelligent QoS can automatically blacklist the IP of users who occupy a large amount of bandwidth. Just keep an eye on the IP in the blacklist. If there is a continuous large amount of occupancy, immediately give it twice. Punishment, the available bandwidth of the IP is reduced to 50%, and then automatically suppresses a large number of occupants, not only reduces the network management burden, but also ensures the stability of the network.

In addition, intelligent QoS can freely set the bandwidth usage threshold (for example, up to 60% of the overall bandwidth) and time (which time period from Monday to Sunday) before starting bandwidth management to achieve peak and low peak periods. Different people on the Internet have different bandwidths, which is the performance of bandwidth utilization optimization. ;;

2, virtual routing greatly reduces the cross-network bottleneck of gamers

The majority of gamers in the Internet cafes How to provide high-quality game services for players to play smoothly is an important key to maintaining a high attendance. Due to the long-standing problem of the interconnection of the South China Telecom North Netcom interconnection, the game players need to connect to different servers of the Telecom Netcom, the online speed will be significantly delayed, which is very disappointing for the players.

Qno's GQF500 has a special virtual routing technology that allows you to select only one ISP with multiple ADSL or one ISP single ADSL line. You can have dual lines (Netcom, Telecom) through a third party. The router is connected to realize the interconnection and intercommunication of the telecommunication network communication. From then on, the player can easily play smoothly, and there will be no phenomenon such as sluggishness of the card network.

3, ARP two-way binding measures internal and external network security without loopholes

Finally, the network management Mr. Feng Jian said that "Flying Fox Network Club" in the initial stage of operation, against ARP and intranet IP spoofing attacks emerged endlessly . After using the Chino GQF500, the built-in ARP basic control function actively detects and filters suspicious packets as the first line of defense against ARP attacks. At the same time, they also listened to the advice of the Chino engineers, and the two-way binding of IP and MAC between the router and the PC to achieve a comprehensive anti-blocking ARP attack. He is naturally a lot easier to do network management, and he can free time to come to the boss for internal management.

As an old user of GQF500, Mr. Feng Jian will also share his experience in the two-way binding process: in fact, two-way binding is not difficult, network administrators can pre-game and movie in each PC and Internet cafe. The IP/MAC is bound by the server, and then the router binds the IP/MAC of each PC on the intranet. In this way, through the bidirectional IP/MAC binding between the router and the PC, the ARP attack and IP spoofing can be effectively avoided.

However, since the IP/MAC binding will be automatically cleared after the Internet cafe client PC is shut down, it is indeed a heavy burden to re-bind the network management one by one. Therefore, the PC can create a BAT file (as shown below), allowing the user to boot automatically to perform IP/MAC binding, which can effectively solve this problem.

BAT file: @echo off arp -d arp -s Router IP address Router MAC address

In addition, you need to further check whether the PC is bound to the router and server IP/MAC, which can be turned on. Dos cmd enters the command ARP -a, the IP and MAC address appear, and the type list displayed on the back end shows whether it is static. If it is successful, if it is dynamic, it means it is unsuccessful.

The network management Mr. Feng Jian has been using GQF500 for more than a year, and has not seen the phenomenon of dropped calls and slow network speeds. It has greatly satisfied the users' Internet expectations and made the "Flying Fox Network Club" in Zhuzhou City. The fierce Internet cafe market competition has more advantages, and strives for more new and old customers, and the business continues to be booming!
