Our dormitory has been equipped with 2 ADSL lines for about 60 students. Most of us just used internet for chatting, web-surfing and email, but there are few guys want to suck all the network bandwidth with their IDM and uTorrent. Due to the poor setup of the networks, the internet become mostly useless.
Now I want to re-setup the network using current hardware (2 modem, 2 router, 1 PC with Windows 2003 installed on - for balance-loading). I'm have very basic knowledge in networking, but I think I will upgrade all router to Tomato firmware for simple management interface, better speed and QoS control. I will set a limit so that no guys can download at a speed greater than 1/5 the overall bandwidth of the whole network (currently it's 2 Mbps)
With these conditions, how do I setup the network so that our students would have some small happiness?
