Downstream Policing
Note: Downstream Policing applies the bandwidth limit to the downstream traffic
equally and drops all packets when the maximum bandwidth is reached even
though the packets have different priorities. If the downstream traffic flows are
assigned different priorities, use Downstream Policing per Queue to make
sure packets with a higher priority can be processed first.

DESCRIPTION
Select a traffic priority level for a logical link.
The higher the priority (larger number), the more likely that the ONU gets the
unused upstream bandwidth (up to the maximum bandwidth setting) after the
minimum bandwidth requirement is met.
Specify the delay tolerance of a logical link for bandwidth allocation when
network congestion occurs.
Select Low Delay for the packets to get serviced faster. This is recommended
when you have real-time applications (such as VoIP) on the network.
Select High Delay to get less service time slots. Packets are serviced slower.
Specify the minimum upstream bandwidth guaranteed to the ONU. Upstream
traffic refers to traffic from the ONU to the OLT.
The number you entered is multiplied by 64.
Specify the maximum upstream bandwidth guaranteed to the ONU. Upstream
traffic refers to traffic from the ONU to the OLT.
The number you entered is multiplied by 64.
Select Active to apply the bandwidth limit to the upstream traffic on the queues
then configure the settings in the field below. Upstream traffic refers to traffic
from the ONU to the OLT.
Specify the maximum upstream bandwidth for packets in queue 0.
The number you entered is multiplied by 100.
Specify the maximum upstream bandwidth for packets in queue 1.
The number you entered is multiplied by 100.
Specify the maximum upstream bandwidth for packets in queue 2.
The number you entered is multiplied by 100.
Specify the maximum upstream bandwidth for packets in queue 3.
The number you entered is multiplied by 100.
Select Active to set the queue size for the upstream traffic.
Specify the size (in byte) for queue 0.
The number you entered is multiplied by 128.
Specify the size (in byte) for queue 1.
The number you entered is multiplied by 128.
Specify the size (in byte) for queue 2.
The number you entered is multiplied by 128.
Specify the size (in byte) for queue 3.
The number you entered is multiplied by 128.
Select Active to control the downstream traffic (from the OLT to the ONU).
