Routers play an indispensable role in internet caf茅s, so the configuration of internet caf茅 routers should receive full attention from network administrators. So, how do you configure a router for a large internet caf茅 with 400 computers?
Some internet caf茅s still use the outdated proxy server method, where a dedicated PC acts as a server with proxy software installed, and all computers in the caf茅 share internet access through this proxy server. The drawbacks of this method are: proxy software installation and configuration is complex, making it difficult for non-professionals to use effectively;
It requires a dedicated server, which is expensive 鈥?high-end ones can cost over ten thousand yuan, and even lower-quality ones cost four to five thousand. Moreover, ordinary PC servers have poor reliability and tend to freeze easily.
How an Internet Caf茅 Router Works
(1) Workstation A sends Workstation B’s address 12.0.0.5 along with the data information in the form of a data packet to Router 1.
(2) After Router 1 receives the data packet from Workstation A, it first extracts the address 12.0.0.5 from the packet header, and based on the routing table, calculates the best path to Workstation B: R1->R2->R5->B; then forwards the data packet to Router 2.
(3) Router 2 repeats Router 1’s task and forwards the data packet to Router 5.
(4) Router 5 similarly extracts the destination address, finds that 12.0.0.5 is on the network segment directly connected to this router, and then delivers the data packet directly to Workstation B.
(5) Workstation B receives the data packet from Workstation A, and a communication process is thus completed.
In fact, besides the primary routing function mentioned above, routers also have network traffic control capabilities.
