Figure 5: Aggregate Marking with Oversubscription

A
B
C
Rate-limits for A, B, C:
Packets under 1 Mbps marked TOS1
Packets between 1-2 Mbps marked with ToS value 20 (A only) or ToS value 30 (B, C)
All packets sent to rate limit S for check for ToS value 10
Configuration A
Peak Rate: 2 Mbps
Committed rate: 1 Mbps
Committed action: transmit conditional
Conformed action: transmit conditional
Exceeded action: drop
G mark: TOS value 10
Y mark: TOS value 20

Receives packets from A, B, C
Packets under 2 Mbps are not affected
Drops packets that exceed 6 Mbps rate
Demotes packets over 2 Mbps
