Guidelines for Controlling the Simple Shared Shaper Algorithm

You can configure the simple shared shaper variables individually, but it is useful to
use configuration guidelines to determine how the variables work together to achieve
a desired behavior.
Table 8 on page 93 displays guidelines for configuring the most liberal shared shaper
to the most conservative shared shaper.
