If you plan to connect four 4M ADSL lines to your local network, each line will of course deliver a theoretical 4M bandwidth. However, that is only the theoretical value. With a telecom 4M connection, the actual download speed tops out at around 400 KB/s. Their 4M calculation is not a simple 1M+1M=2M. Some can only serve as backup, meaning when one line goes down, another line is activated 鈥?for instance, the Qno FVR420V, a 4-WAN port broadband router designed for Internet cafes, connects four ADSL lines and balances traffic across all four lines.
The key to smooth Internet cafe operations is having a stable and secure network system that can provide customers with a satisfying online entertainment and leisure experience. Web browsing, OICQ, video chat, video streaming, and high-traffic online games consume a great deal of network system resources, all while handling heavy user traffic.
Therefore, Internet cafes need router products specifically designed for Internet cafe use 鈥?supporting a large number of users, high access rates, fast processing speeds, strong compatibility, and excellent scalability 鈥?all at an affordable price that fits Internet cafe operating costs.
To meet the emerging demands of Internet cafe applications, dedicated Internet cafe routers were introduced. They support stable and efficient access for medium and large Internet cafe network systems and can effectively solve the common problems found when using SOHO routers. They offer the following advantages: first, Internet cafe dedicated routers possess carrier-grade stability and high performance, ensuring high-speed Internet access without disconnection; their rich hardware firewall features can prevent illegal network intrusions and viruses like Blaster, and users can flexibly customize or add firewalls according to the system’s security requirements.
Second, considering the Internet cafe usage environment, dedicated Internet cafe routers feature meticulous thermal design with well-thought-out heat dissipation, effectively solving the system’s cooling issues and ensuring each unit can withstand the high-temperature conditions generated by prolonged operation.
Moreover, Internet cafe dedicated routers typically use 32MB or larger high-speed memory and 8MB or more FLASH storage. Their system configurations are far superior to those of SOHO routers, with high-performance dedicated CPUs and strong scalability.
One function of a router is to connect different networks, and another is to select the path for information transmission. Choosing a smooth and swift shortcut can significantly increase communication speed, reduce communication load on the network system, save network system resources, improve the network system throughput rate, and thus allow the network system to deliver greater efficiency.
From the perspective of filtering network traffic, the role of a router is very similar to that of a switch and a bridge. However, unlike a switch that
