Network scheme: network construction utility program fine Internet cafes Collect
First, the application needs of Internet cafes
With the development of information society, the concept has been sweeping the Internet cafe the streets of the country, but, with the increase of Internet cafes, also intensified the competition among industries, intense competition in order to survive and ensure good operation of the network efficiency and stability of the network system performance in Internet cafes in the building becomes more important. How can we ensure the stability of network systems work 24 hours to provide users with a comfortable, stable network environment? Internet cafes have become the focus of increasing concern.
Main applications of Internet cafes, mainly in the following areas:
Access Internet: through access to Internet, to achieve browsing information, entertainment, etc.
Multimedia applications: VOD video on demand, music, etc.
Online game: online games Application of Internet cafes mainly to meet the individual users on a variety of multimedia video, online games, browse information, information exchange and other stringent requirements, especially for large numbers of users access the server resources to ensure high-speed network to access Internet, therefore, How to build a network to provide users with a fast, reliable and stable network environment, it has become increasingly concerned about Internet cafe owners to the most important issue. The author recommended
network solutions, network equipment vendors with reference to Internet cafe solution, using hierarchical network structure, and through the mature Ethernet technology, providing users a high-performance, high availability, high stability , secure and reliable network environment.
Second, Internet development solutions 1, a small Internet cafe building programs (less than 200 terminals) Although the business area of such bars
relatively small number of computers are also relatively small, the network topology is simple, easy to manage, but often users access the server, the server access bottlenecks often appear for users to access network resources inconvenience . Therefore, the solution uses two-story structure: the core layer and the user access layer, the use of advanced technology Fast Ethernet switch between the cascade, to meet the ordinary web, chat, send and receive mail, games, and a number of against the video server and game server access
Center switch using des-3526/3550 switches, all the server directly connected to the central switch, to enhance the network throughput and the exchange rate.
Key Features 24/48 a 10/100BASE-TX port

DES-3526/3550 2 layer stackable switch
Branch switch: Using multiple Des1024 unmanaged 10/100M switch. Des1024 with 4.8Gbps backplane switching capacity. Provide full-duplex wire-speed 24 10/100M ports, up to 16K of the MAC address table per port work in the 10M or 100M, the packet forwarding rate is 14.8K / s; the maximum delay of only 10u / s; to really fast Ethernet performance requirements for Internet cafes within the game provides a good stable of running the bandwidth. In addition Des1024 also supports auto-crossover cable or straight to adapt to networking line, to facilitate connection to the computer card; simple LED status display for easy network management and intuitive view switch operating conditions.
Network topography as shown below: Program features: TRUNK advanced technology, the server directly into the central switch, to solve the bottleneck server access; Trunk distributors
switch settings, easy to install video server, the server network card's high-volume multi-server access.
Supports full line rate forwarding, to ensure efficient and stable network;
Typical user: 130-bit Internet cafe computers
