I understand what you’re saying, now, but in terms of the end user experience, there is a point in queuing some incoming packets on the router. In this case, there are many users at a camp, and the office and admin needs have to be prioritized over the campers’ Facebook browsing. By putting all the campers in a 1 Mbps. incoming queue, the 3 Mbps. pipe does not get bogged down for other users. At least, that’s how it appears to work. Obviously, putting all traffic in a throttled queue would be pointless.
