CoS2 is configured for 100Kbs and CoS6 for 300Kbps, CoS2 takes 100Kbps when
there are no CoS1 packets. CoS6 can take 300Kbps when there are no CoS1 or
CoS2 packets.
PRIOWRR
Queues CoS2 to CoS6 are serviced round robin. CoS1 has the highest priority and
is not controlled by the WRR data shaping algorithm.
PRIOWRR does not use
Max Rate
. Percentages of packets received are sent out.
CoS2 to CoS6 will not be serviced while there are CoS1 packets. CoS2 to CoS6 will
share based on the percentages of the packets. PRIOWRR is similar to Low
Latency except that Low Latency is rate based and PRIOWRR is packet based.

Example 1: HTB Queue Discipline Enabled
In the example below, HTB Queue Discipline is enabled. The PPPoE1 connection has a total of
300 kbits of bandwidth, of which 100 kbits is given to CoS1 and another 100 kbits is given to
CoS2. When there is no CoS1 or CoS2 packets, CoS6 packets have the whole 300 kbits of
bandwidth.
