I did two sets of runs, one with the wire bandwidth limited to 300kbps, and one with it limited to 1Mbps

• The solid lines represent the measured data
• The dot on the solid line (if present) represents the predicted point after which the router saturates its outbound bandwidth
• The dashed line (if present) is the predicted curve for the solid line of the same color
