JUNOSe 11.1.x Quality of Service Configuration Guide
Through QoS parameter definitions, the QoS administrator defines a QoS scheduler
hierarchy that corresponds to the physical network topology shown in Figure 60 on
page 244.

Figure 60: Physical Network Topology

The S-VLAN scheduler nodes correspond to the DSLAM in the physical network
topology; the VLAN scheduler nodes correspond to the subscribers.
Figure 61 on page 244 shows the QoS scheduler hierarchy that the QoS client creates
when configuring a different service for each subscriber.

Figure 61: QoS Scheduler Hierarchy

For Subscriber 1, the QoS client configures a basic best-effort data service, with a
maximum rate of 2 Mbps, and assigns a scheduler weight value of 1.
