Discipline limited. So in the example above CoS1 data is not rate limited to
100Kbps but instead all 300Kbps is transmitted. The side effect is
that a misconfigured stream can potentially take all bandwidth.
PRIOWRR This is a priority based weighted round robin algorithm operating on
CoS2-CoS6. CoS1 queues have the highest priority and are not
controlled by the WRR algorithm.
Of the three shaping algorithms available on the Shaper Configuration page, only one can be
enabled at a time. An example of each configuration is given as follows.
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 bandwith, 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
bandwith.
