Comprehensive Analysis of Internet cafe ADSL line access network formation

This article provides a comprehensive analysis of the network construction for Internet cafe ADSL line access. The principles, ideas, and test procedures of password retrieval are described in depth. The network applications of Internet cafes must combine advanced, multi-service, scalability, and stability to meet customers' needs for simultaneous transmission of voice, video, and data over broadband networks, it also supports a variety of new business data processing capabilities, and enables high-speed access to the Internet. Big data traffic is not dropped or paused.

Next, we will briefly introduce a flexible solution for creating Internet cafes. During the past eight years of development, the Internet cafe industry has been criticized. Recently, in order to regulate the normal operation of Internet cafes, the country has guided the healthy development of this industry, large and medium-sized Internet cafes have been supported in the policy.

In order to achieve unified management, the current Internet cafe scale and development trend is also basically a large-scale, regular operation line. The Internet cafe's business path determines that it must have a high-speed, stable, and secure network system in order to maintain a sound development. Next, we will briefly introduce a flexible Internet cafe construction solution for scale expansion:

Demand Analysis: Internet cafe ADSL line access is a special environment in network applications. Nodes in Internet cafes are constantly browsing, chatting, downloading, video-on-demand, and online games at the same time. The data traffic is huge, especially for Internet users who come to Internet cafes for consumption, the demands for Internet access vary, and applications are complex.

Internet cafes have diversified network application types and have higher requirements on network bandwidth, transmission quality, and network performance. Network applications must integrate advanced, multi-service, scalability, and stability to meet customers' needs for simultaneous transmission of voice, video, and data over a broadband network, it also supports a variety of new business data processing capabilities, and enables high-speed access to the Internet. Big data traffic is not dropped or paused.

Such applications require that network devices have rich features and high stability and reliability, so as to ensure uninterrupted and stable operation for a long time, the configuration is simple, easy to manage, and easy to install. the user interface is user-friendly and easy to understand, and cost-effective.

Access Solution: In many Internet access methods, Internet cafe operators usually choose ddnleased line and Internet cafe ADSL line access. DDN is naturally not as cost-effective as Internet cafe ADSL line access, in addition, Internet cafe ADSL lines can easily achieve low cost and high bandwidth through the bundling Technology of multiple WAN ports. If it is a large-scale Internet cafe, it requires a high speed, using a multi-channel bundle that supports a 4-Wan port, and selecting different ISPs, it is easy to achieve high-speed browsing of various websites. Solution: Large Scale and flexible configuration. The device selection is also very flexible, there are a variety of devices to choose from. Scale can be adjusted based on actual conditions, and related technologies are very mature.

Solution Description: The Cisco 1700 series vro provides stable performance and high reliability. Low latency, fast speed, and low cost, which meets the speed requirements of Internet cafes. For example, a printer can be configured with 1700 without having to configure another printer server. The workstation of the Internet cafe uses a high-performance corumeng 8139D 10 M/M Adaptive Nic to increase the network speed and meet the requirements of online game players.

The server uses a Gigabit Ethernet switch to meet game data traffic requirements. General switch Selection in addition to the models listed in the diagram, can be based on the actual situation Flexible Choice of Alliance intelligent switch COM-SF2224P, or alliance double speed switch COM-SF1024/1016.

Local Area Networks access the Internet through Internet cafes through ADSL lines, with high performance and low prices. For large Internet cafes, due to the large number of nodes in the network and the large data traffic, you can apply for multiple Internet cafe ADSL line access lines to speed up the Internet (for example, two lines ), at the same time, it can improve the stability and reliability of the entire network and play a certain role in backup. Kemeng technology has many network devices and features stable performance. You can choose the network type based on your actual needs.

Features:
◆ You can flexibly control different Internet access permissions of different users in the LAN as needed;
◆ Built-in firewall, which can filter out all exceptions from external sources without the need for specialized Firewall Products to protect the information security of the internal LAN;
◆ The DHCP server is integrated. All computers in the network can automatically obtain TCP/IP Settings, avoiding manual IP Address Configuration troubles;
◆ Flexible Scalability: The vswitch or hub is used to expand according to the actual number of connected computers;
◆ Economical and easy to use. You can use a Web browser (Netscape or Internet Explorer) of a network user to remotely configure a vro.

Note: In theory, Cisco 1700 can connect up to 255 clients. However, considering the large number of connections, its processing capability will cause bottlenecks and the network speed will also be affected (after all, an internet cafe ADSL line cannot be connected to too many clients ). Generally, it is recommended that the number of connected clients be less than 100 to 70 ~ 80 is the best configuration. In this way, we can not only ensure that the network speed is not affected, but also make full use of resources to save money.
