What is the so-called number of hosts that can be sent to a router in an Internet cafe?

The number of routers with Internet cafes, as the name implies, is the number of computers that can be loaded by routers. Generally, manufacturers can use their own vrouters with 200 or 300 PCs in the performance parameter table. However, in many cases, the performance of vrouters differs greatly from the nominal value.

This is because the number of vrouters in Internet cafes is directly affected by the Network busy in the actual environment, and the number of vrouters varies greatly in different network environments. For example, in Internet cafes, almost all people chat online, play games, and watch online movies at the same time. The data must pass through the WAN port, causing heavy load on routers.

While on the enterprise network, only a small number of people are using the network at the same time, and the router load is very light. Therefore, if you place a vro in a CEN with 200 pcs in an Internet cafe, 50 PCs may not be moved. Estimating the average data traffic of each PC in a network cannot be accurate.

In a vro with enough enterprise network performance for 200 pcs, it is often impossible to connect 50 PCs to an Internet cafe. Estimating the average data traffic of each PC in a network cannot be accurate.

Therefore, a more objective statement should specify the type of network for which the bandwidth is based, and the scope is estimated based on typical situations. For example, "the bandwidth of an internet cafe router is 150 ~ 250 (typical )".

In addition, some routers refer to the "maximum allowed number of incoming IP addresses". This statement does not refer to the performance of the router, but to the maximum number of IP addresses that can be allocated by DHCP, the loss of 254 million items is 253, which is meaningless to users.

In addition, there is also a saying that the router is a dual-WAN port, and the performance is twice that of a single WAN port. "" A single WAN port carries 100 machines, and a dual WAN port carries 200 machines. This statement is not true. Some vrouters of different brands are currently on sale, but their performance is poor.

A vro with multiple WAN ports must first be built on the premise that the performance of the vro itself is strong enough, and the processing capability of the vro with respect to the egress bandwidth is sufficient. If the processing capability is limited, the multi-Wan port is purely a decoration. When selecting a multi-Wan port router, you must carefully check its performance.

Finally, I would like to explain that the number of routers with machines in Internet cafes is only an estimate and an empirical value. You must pay attention to the mistakes mentioned above when referring to this data. When purchasing an internet cafe router, You need to view the actual network conditions. The accurate performance depends on the test data. In addition, if this data is from a large manufacturer or reputable manufacturer, it is generally rigorous and highly reliable. If it is from a small manufacturer or manufacturer of miscellaneous brands, the general statement is vague and the credibility is poor.
