Frames are shown as broken lines below the Access Rate line. The space between frames
indicates the delay between the transmission of each frame. For each second, frames sent
within the white zone below the diagonal Access Rate line get through. The shaded area just
above the white area contains frames that are stamped for Discard Eligibility that will get
through as long as the VC is not congested. The darkest shaded area shows frames that may
not get through because they exceed the Excess Burst Size allowed in one second.
