Consultant to the owner
Basically you will need to implement a bridge between the router and the rest of the network. In order to build a software bridge you will need a separate computer equipped with two network cards. This computer will need to be plugged between the router and the switch. This is briefly outlined here. After that you will be able to create bandwidth management rules based on student computers MAC or IP addresses and impose a download cap as required.
