In this graph, the x-axis is labeled "Connection 1 throughput" and the y-axis is labeled "Connection 2 throughput." The right-most point on the x-axis and the top-most point on the y-axis are both labeled R, and these points are connected by a black line, labeled "Full bandwidth utilization line," that bisects the graph diagonally in half. A blue line, labeled "Equal bandwidth share," begins at the intersection of the x- and y-axes and extends diagonally upward at a 45-degree angle along the x-axis, also bisecting the graph in half. These two lines form an X. In the lower right-hand quadrant of the X, we see a series of blue arrows pointing back and forth across the black line, starting at about the halfway point and moving upwards to the right towards the intersection of the two lines. The first arrow extends from point A on the left to point B on the right, then from B to C, from C to D, and so on.
