A hotel has 72 rooms, and each room has a computer. How many megabytes of internet do you need? How to configure routers and switches?

First, apply to Telecom for 100M network cable.

Buy three 20-port switches and 1 15-port switches.

Buy a 4-port or 8-port PBX

100M is connected to a four-port switch and distributed to four other switches.

Four-port switches are divided into 10M to 15 switches and 30M to 20 switches.

Set the peak traffic of each port to 2M on the 15 port switch.

Set the peak traffic of each port to 2M on the 20-port switch.

You are a hotel, not everyone who checks in needs to surf the Internet. Even if you want to go to QQ and open a webpage, 2M is enough.

Try it for a while. If you have a card, you can apply to Telecom for an appropriate increase in traffic or adjust the peak traffic of the router.
