Too much traffic, one small link
The link carries 10 packets a tick and the buffer holds 40. Eight flows want 3 packets a tick each, and every third flow is high priority. Choose how the network reacts and compare the cost.

Delivered is the share of everything users wanted to send. This model has no retransmissions, so it shows the cost of no control as drops and delay, not the full congestion collapse a real network can suffer.
