Example: QoS Parameter Configuration for IP Multicast Bandwidth Adjustment
In this example, a QoS administrator configures a QoS parameter definition to
associate with the IP multicast bandwidth adjustment application.
The QoS administrator configures the parameter definition to perform the QoS
adjustment on an ATM VC subscriber. By specifying the
ip-multicast keyword with
the qos-parameter-define command, the IP parameter instances are created when
the Internet Group Management Protocol (IGMP) joins and leaves.
When you specify a controlled-interface type for atm-vc, the system explicitly creates
a parameter instance at the ATM VC with a value that is equal to the sum of the IP
adjustments above this interface. This parameter value is referred by a scheduler
profile and a QoS profile to create the QoS scheduler hierarchy that adjusts the
shared-shaping rate when IGMP joins and leaves.
This subscriber has data, voice, and video service with total subscriber bandwidth
of 10 Mbps. Voice traffic is shaped at 192 Kbps and belongs to the strict priority
group. Video traffic is provided by the IP multicast bandwidth adjustment application
and its rate is configured in the bandwidth map.
Figure 63 on page 274 shows the scheduler hierarchy built in this configuration.
