Constituents; Figure 35: Case 2: Explicit Constituent Selection With Weighted Constituents; Table 13: Bandwidth Allocation For Case 2 Explicit Constituents - Juniper JUNOSE 11.1.X - QUALITY OF SERVICE CONFIGURATION GUIDE 3-21-2010 Configuration Manual

Figure 35 on page 119 illustrates another case where scheduler profiles B, X, Y, and
Z are applied to scheduler objects. Each profile assigns a weight to an explicit
constituent.

Figure 35: Case 2: Explicit Constituent Selection with Weighted Constituents

In Case 2, scheduler profile B associates the shared-shaping rate with the best-effort
node for VLAN 1. Table 13 on page 119 lists the explicit constituents of the shared
shaper and the bandwidth allocated to each constituent:

Chapter 13: Configuring Implicit and Explicit Constituent Selection for Shaping
Explicit Constituent
VLAN 1 TC voice1 queue
VLAN 1 TC voice2 queue
VLAN 1 TC video queue
Best-effort node for VLAN 1
Bandwidth Allocation
Strict constituent that can consume up to its legacy
shaping-rate.
Weighted constituent that shares bandwidth with its weighted
shared shaper siblings in a proportion of 4/10.
Weighted constituent that shares bandwidth with its weighted
shared shaper siblings in a proportion of 3/10.
Weighted constituent that shared bandwidth with weighted
shared shaper siblings in a proportion of 3/10.
NOTE: The node is selected as the constituent when both the
node and the queues stacked over node are specified in a
scheduler profile.
