Example: Compound Shared Shaping for ATM VCs

Figure 27 on page 102 illustrates a typical DSL triple-play configuration, involving
voice, video, and data traffic. In this example, a total of 1 Mbps of bandwidth is
allocated to voice, video, and best-effort data traffic associated with the VC 1 logical
interface.
The voice queue in the EF traffic-class group for VC 1 is a strict constituent that has
first claim on up to 200 Kbps of the shared bandwidth. The video queue in the AF
traffic-class group is a strict constituent that can claim up to 300 Kbps of the remaining
800–1000 Kbps of shared bandwidth. The best-effort queue for logical interface VC
1 is a strict constituent that has the last claim to the remaining 500–1000 Kbps of
shared bandwidth.
