Internet cafe network comprehensive Problem Discussion and Solution

The entire Internet cafe industry also supports employment of more than 1 million people, and the annual output value can reach nearly 30 billion in a year. Internet cafes, large and small, have spread all over the country, whether in large and medium-sized cities or small cities until very small county towns. As an important place for Internet access, Internet cafes not only provide convenient Internet access conditions for Internet users, but also become an operational model. With the increasing number of Internet cafes, the competition between industries is becoming increasingly fierce. in order to stay competitive, the cost control, operation performance, and management and maintenance of Internet cafes have become an extremely important factor. Therefore, we have made some discussions and provided some basic solutions to the comprehensive problems of Internet cafes for your selection and consideration, strive to form a low-cost, high-performance, and easy-to-manage Internet cafe network management solution.

First, let's take a look at what are the main problems with an internet cafe:

Internet cafes are actually most worried about several things in terms of management. One is frequent disconnection, the other is slow speed, and the other is virus. In fact, these are the most important and core problems in Internet cafe management.

The first is frequent disconnection. Frequent disconnection may lead to loss of customers. It is estimated that old customers will not be able to stay. In the early days of Internet cafes, occasional latencies, dropped connections, and other phenomena did not have a significant impact on users. When computers were disconnected, a greeting would have passed. However, with the popularity of real-time online games, every disconnection is a direct economic loss for players. This means that the loss of experience, grade, and equipment is the result of online games, some losses, even irreparable, will lead to direct loss of customers. Therefore, dropping Internet cafes is the most worrying thing for many Internet cafes. In this situation, many Internet cafe owners believe that they have experienced it.

The second is the slow speed of Internet access, which is not a small headache for Internet cafe operators and managers. Going to the internet cafe is a high speed of surfing the Internet. If many customers use QQ to chat with netizens, the image response speed is very slow, and the voice quality is poor, the latency is very obvious, if both parties cannot hear the other party, the communication will be seriously affected. In addition, it will also cause the poor effect of watching movies on the Internet, which is often buffered and intermittently. It is difficult to complete a movie. The slow speed of Internet access directly affects the satisfaction of Internet cafe customers, thus affecting the operation of Internet cafes. When the number of Internet users in Internet cafes exceeds a certain number, it is difficult for the computer to log on to QQ. Even if the speed is low, it is very slow to open the web page, leading to the loss of customers. This is also one of the main problems that occur in Internet cafes. It is necessary to quickly restore or reduce such problems.

The other is the problem of network virus flooding. If the virus damage seriously, it will damage the interests of users. With the popularization of various network attack technologies and the proliferation of viruses, virus intrusion and illegal attacks are already the biggest security risks for Internet cafes. Any download from Internet users may carry viruses to any extent, and vicious competition between Internet cafes may also lead to mutual attacks. If the Internet cafe cannot solve the virus and attack problems, it will paralyze the entire network. Trojans and viruses are also a major threat to online games. If these Trojans cause damage to online game players by hacking and stealing equipment due to the negligence of Internet cafes, this will also result in the loss of a large number of Internet cafe customers. This is also one of the headaches of many Internet cafes.

The last step is the huge maintenance cost caused by difficult device management. This is also a major problem in the operation of Internet cafes. For example, some Internet cafes do not use routers at the egress, but directly use proxy servers. Once the proxy server crashes, maintenance and inspection takes a lot of time, the Troubleshooting is normal, and many online users may leave without waiting, resulting in loss of Internet cafe operation. In addition, equipment maintenance is always a headache for Internet cafe operators. Equipment Maintenance for Internet cafes requires professional network technicians and is complicated to maintain. Therefore, how to better manage and maintain the network becomes an important issue to be considered during network construction, sometimes there is a problem with the internet cafe equipment, so it can be well maintained for several hours, which has a great impact on the operation of Internet cafes.

In fact, whether it is a disconnection, slow access speed, or high virus and management costs, these all need to be as robust and secure as possible in the construction of the network platform. Currently, online network applications in Internet cafes are complex and diverse. Such as online games, video chats, online movies, and music. These diversified real-time applications are a great test for the operation of network platforms and Internet cafes. Therefore, these problems need to be solved in many aspects to ensure the normal operation of Internet cafes.

We still need a robust network platform to avoid these major problems as much as possible. Internet cafes need to provide users with Web browsing, sending and receiving emails, QQ chats, online games, and online videos, and the same user may carry out multiple activities at the same time, all these applications are implemented with the support of the network platform. The robustness of the network platform directly affects the operating effect of Internet cafes. A robust network platform should be stable and reliable, featuring high speed and low latency, anti-virus attack prevention, and simple network maintenance.
Let's take a look at how to solve these basic problems through some strategies to form a stable and robust network environment and ensure the normal and smooth operation of Internet cafes.

The first is how to solve the problem of disconnection, so that the Internet environment of Internet cafes can be stable and reliable. Internet cafe access methods generally use routers as the dedicated line for connecting the network egress device to the operator. Currently, the operator provides 10/100 M lines and can connect to the egress router through a photoelectric converter, the egress router is connected to the core switch of an internet cafe through an Ethernet twisted pair. To ensure network stability, first, the stability of the device itself is required. Network equipment can work continuously for a long time to ensure normal operation of Internet cafes. Second, the stability of equipment and software, and the integrity of operating system development. Third, to meet the needs of multi-line access, you can deploy two routers at the egress, And you can set up devices to enable mutual backup. In this way, you can prepare two egress routers in the Internet cafe, when one of them fails, all traffic can be switched to another router. In addition, because the carrier line may be faulty, it is best to select a router with the line backup function, so that when one line fails, it can be automatically switched to another backup line immediately. Generally, Internet cafes should apply for two lines, one for China Telecom and the other for China Netcom, and the other for mutual backup. In IP settings, many Internet cafes place all IP addresses in the same CIDR block. Although configuration and maintenance are simple, broadcast storms may occur. Transmission information may be delayed. In severe cases, network devices may be disconnected from the network, or even the entire network may be congested or paralyzed. Therefore, it is best to divide VLANs on the egress router or core switch to avoid network broadcast storms as much as possible.

The second is how to avoid problems such as slow access and serious network congestion. Currently, Internet cafes are mainly used to browse Web pages, online videos, and online games. These three applications require high Internet access speeds. In particular, online games require high performance processing for network devices. In fact, the bottleneck for Internet access is mainly in the packet forwarding rate and address translation functions, which can be implemented on the router device, select a good router, in particular, the high processing frequency can ensure the efficiency of packet forwarding rate. If the memory is large, the address can be converted, that is, the better the NAT performance.

Within the Internet cafe, the switch can have all ports that can achieve high-speed data forwarding requirements, two-way MB or GB line rate forwarding. In this way, the access of various servers within the Internet cafe can be fast and efficient, and the internal access speed can reach a very stable State. In this way, the various game Servers configured in the Internet cafes on a large scale are now available, the movie server and VOD Server can work very well and solve the access bottleneck of the main internal servers.

This is also a manifestation of network security. With the rapid popularization of the Internet, network security problems such as computer network viruses, operating system vulnerabilities, and spam are also emerging all over the world, causing losses. An Internet cafe contains hundreds of thousands or even hundreds of machines. It is often difficult to cope with a variety of viruses, and it is always necessary to guard against malicious hacker attacks. Currently, Internet and Intranet attacks are mainly targeted at Internet cafes.

Internet attacks: Generally, network hackers initiate distributed DDOS denial-of-service attacks on Internet routers or fiber-optic lines by controlling a large number of computers with Trojans) the attack causes network congestion or equipment paralysis, making the Internet cafe unable to operate normally.

Intranet attacks: Due to the endless rise of system vulnerabilities, network viruses, and various attack software against the network, can be downloaded everywhere on the Internet. Making the network system, server, router, and other key devices of Internet cafes vulnerable to attacks at any time, resulting in a decline or even complete breakdown of network performance, posing a great threat to the normal business of Internet cafes. Common Intranet attacks include ARP, DDOS, and network worms. The ARP spoofing virus is currently popular. It builds a fake gateway to send data to the fake gateway instead of accessing the Internet through a normal router. These basic attacks and virus access routes can be avoided by the vro itself. You can select a vro with the anti-attack function to prevent common attacks, for example, DOS/DDOS attacks, ICMPFlood attacks, address scanning, and port scanning can also prevent ARP spoofing. In this way, we will do our best to improve the network environment and minimize the impact of viruses on the network environment of Internet cafes.

The last step is to solve the problem of managing the network devices of Internet cafes. The principle of solving this problem is to simplify network management as much as possible. After buying network devices from Internet cafes, management and maintenance are costly. Because many Internet cafe administrators do not have very professional computer network knowledge, this requires the selected device to be easy to install, easy to configure, easy to manage, and easy to use. The user debugging management interface is user-friendly and easy to use, it is best to use Web management control. To some extent, this can greatly shorten the internet cafe system maintenance and fault repair time. For example, if an internal switch supports AutoMDI/MDIX, you can eliminate the confusion between the main line and the reverse line. In addition, if a network problem occurs, you also need to be able to locate the problem in time, locate the root cause of the problem and solve it, in this case, the log function is used to quickly locate the problem by analyzing the running and operation logs of network devices.

The four major problems of disconnection, slow speed, poor security, and difficult management are the most common and headaches for Internet cafes. Through in-depth analysis of the internal causes of these four problems, we can summarize a series of solutions and related technologies. The following is a list:

1) if the device is unstable due to disconnection, you can use professional hardware devices and stable and reliable operating systems. In this case, you can use dual-host Hot Standby technology.
2) If the carrier line fails, you can apply for multiple lines for line backup.
3) if the network broadcast storm is serious, you can use VLAN Technology to reasonably divide different regions.
4) if the network speed is slow and the Internet access speed is slow, we can improve the forwarding performance of the router and optimize the NAT efficiency.
5) if the network speed is slow and the Intranet forwarding speed is low, the switch can have bidirectional line rate forwarding capability.
6) if the on-demand video streaming speed on the Intranet is slow, you can use the Qos service to ensure that the video stream is prioritized.
7) for network viruses, ACL access control can be used to restrict ports used by common viruses.
8) for ARP spoofing flood, you can use free ARP to select a router that supports anti-ARP spoofing.
9) for device management and maintenance, it is best to use web management and try to use devices that support web management.
10) for troubleshooting of device faults, you can use the log function to record operation diaries and Internet access logs.

Through these methods, you can greatly improve the management of Internet cafes, so that the management and maintenance of Internet cafes form a virtuous circle, facilitating the operation of Internet cafes. Then, we will provide specific solutions to the faults that occur during the operation of Internet cafes for your reference.
