Simple Shared Shaping Algorithm Overview

This chapter provides information for configuring variables within the simple shared
shaper algorithm on the E Series router.
QoS topics are discussed in the following sections:
Simple Shared Shaping Algorithm Overview on page 85
Variables of the Simple Shared Shaper Algorithm on page 87
Guidelines for Controlling the Simple Shared Shaper Algorithm on page 88
Configuring Simple Shared Shaper Algorithm Variables on page 89
Sample Process for Controlling the Simple Shared Shaper Algorithm on page 90
You can configure variables within the simple shared shaper algorithm to control the
minimum dynamic rate for all simple shared shapers on the router.
Configuring variables in the simple shared shaper algorithm is useful for IPTV
configurations. Without limiting the dynamic rate, best-effort data traffic can be starved
for a few seconds when a video stream starts. The minimum dynamic rate defined by
shared shaper algorithm variables applies to best-effort traffic only.
Figure 22 on page 85 shows a two-constituent simple shared shaper consisting of
best-effort and video traffic. The sum of the best-effort and video traffic is shaped to
the configured shared-shaping rate.
