The most liberal case heavily reduces VOQL and changes of rate, leading to a shared
shaper that quickly converges. The conservative configuration overreacts to VOQL
and the change of rate, and converges very slowly.
Figure 25 on page 96 shows a graph of the dynamic rate when the video flow starts.
Figure 25: Dynamic Rate When Video Flow Starts
Stopping Video Flow
Table 10 on page 96 lists the dynamic rate as the video flow stops for the five classes
of simple shared shaper controls. Results might vary because the amount of video
measured in the first falling period is random, in the range 0–4 Mbps non-inclusive.
