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 1 displays guidelines for configuring the most liberal shared shaper to the most conservative shared shaper.

• Most liberal—Appropriate when over-queuing is not a concern
• Liberal—Appropriate when over-queuing is not a concern and a smoother rate adjustments are desirable
• Moderate—Default settings
• Conservative—Appropriate when over-queuing is a major concern
• Most conservative—Rarely appropriate.
