Rate-limits for A, B, C:
Packets under 1 Mbps marked TOS1
Packets between 1-2 Mbps marked TOS2 (A only) or TOS3 (B, C)
All packets sent to rate limit S for TOS1 check
Configuration:
A
Peak rate: 2 Mbps
Committed rate: 1 Mbps
Committed action: transmit conditional
Conformed action: transmit conditional
Exceeded action: drop
G mark: TOS1
Y mark: TOS2
R mark: TOS2
B, C
Peak rate = 2Mbps
Committed rate = 1 Mbps
Committed action: transmit conditional
Conformed action: transmit conditional
Exceeded action: drop
G mark: TOS1
Y mark: TOS3
R mark: TOS3
Rate-limit S:
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
