Shaper
The Shaper Configuration page is accessed by selecting Shaper on the Advance
main page.
Interface: The selections are WAN/LAN interfaces except WLAN, which does not
support Shaper feature. This field needs to be selected before shaper
configuration.
Max Rate: This field is applicable for the HTB Queue Discipline and Low Latency
Queue Discipline; both are rate-based shaping algorithms.
HTB Queue Discipline: The hierarchical token bucket queue discipline is a
rate-based shaping algorithm. This algorithm rate shapes the traffic of a class
over a specific interface. All CoSx traffic is assigned a specific rate to which data
will be shaped to. For example: If CoS1 is configured to 100Kbps then even if
300Kbps of CoS1 data is being transmitted to the interface only 100Kbps will be
sent out.
Low Latency Queue Discipline: This is similar to the above algorithm except that
CoS1 is not rate 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 miss
configured 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.
