How to purchase devices related to wireless networking: How to purchase routers for large Internet cafe access in Complex Networks (1)

A large Internet cafe router is a very important device in the network environment. In the complex network application environment of Internet cafes, how to select a proper router is often an important factor that determines the success or failure of network construction.

For Internet cafes, the main problem to solve the access line is to use fiber-optic access with large bandwidth. Generally, dozens of MB is necessary. Otherwise, it will not be able to smoothly support online games and QQ video chats on the Internet, most routers can use an optical fiber transceiver to convert the optical fiber line into a conventional network cable line. Some routers also have optical fiber module plug-ins, which can be directly connected to the optical fiber line by installing the optical fiber module. The multi-WAN technology is not a common solution for Internet cafes to solve bandwidth. Its more significance lies in North-South intercommunication. One WAN port is connected to the telecom line and one WAN port is connected to the Netcom line, smart access load balancing is achieved through the configured IP address access policy, so many Internet cafe routers use several WAN ports. Some Internet cafes also adopt optical fiber + dual lines to achieve smooth and high network speeds.

In addition to fiber access and multi-Wan port load balancing, large Internet cafe routers also need to consider the security performance and Intranet management and monitoring functions of routers. Broadband routers in normal internet cafes have no advantages in large Internet cafes. They are generally applicable to small and medium Internet cafes. However, this is a general situation. Some common Internet cafe broadband routers are doing very well in terms of security and Intranet control because they spend less on other functions, strong security and Intranet control functions, such routers are favored by Internet cafe investors. To cope with complex networks, in addition to the several aspects mentioned above, there are more factors to consider, such as the number of routers with machines, smart NAT, traffic control, and even after-sales services of products. The following describes in detail the single WAN port Internet cafe Broadband Router, dual WAN port Internet cafe router and router with fiber module.
