ADSL Access Network is the most suitable access method for Internet cafes

The ADSL Access Network is a common access method for Internet cafes. So I have studied the solutions and instructions for the ADSL access network, and I will share them with you here, hoping they will be useful to you. 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 Internet cafe ADSL Access Network Construction solution for scale expansion.

In recent years, 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 to facilitate unified management. Therefore, the scale and Development Trend of Internet cafes are basically a line of large-scale and regular operation. 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.

Requirement Analysis:
Internet cafe ADSL Access Network 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:

Among the many Internet access methods, Internet cafe operators usually choose ddnleased lines and ADSL Access networks. DDN is naturally less cost-effective than ADSL access networks, in addition, the ADSL access network can easily achieve low cost and high bandwidth through the bundling Technology of multiple WAN ports. If it is a large-sized Internet cafe, it requires a high speed and uses a multi-channel bundle that supports 4 WAN ports, in addition, you can easily achieve high-speed browsing of various websites by choosing different ISPs.

Solution:
Large scale, 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 Cisco1700 series 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. Internet cafe workstations use a high-performance corumeng 8139D10M/M Adaptive Nic to increase 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.

The local area network accesses the Internet through the ADSL Access Network. The performance is high and the price is low. For large Internet cafes, because the number of nodes in the network is large and the data traffic is large, you can apply for multiple ADSL access network lines to speed up the Internet (for example, 2 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 InternetExplorer) to remotely configure a vro.

Note: In theory, Cisco1700 can connect up to 255 clients. However, considering that the number of connections is too large, its processing capability will cause bottlenecks and the network speed will also be affected (after all, an ADSL access network 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.
