QoS Shaper Configuration
The Shaper Configuration page is accessed by selecting Shaper on the Advanced main page. Three shaper algorithms are supported:
HTB
Low Latency Queue Discipline
PRIOWRR
QoS Shaper Configuration
Note: Egress TCA is required if shaper is configured for that interface.
Field | Description |
|
|
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 |
| |
|
|
HTB Queue | The hierarchical token bucket queue discipline is a |
Discipline | rate shapes the traffic of a class over a specific interface. All CoSx traffic uses a specific rate to |
| which data will be shaped. 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 | This is similar to the above algorithm except that CoS1 is not rate limited. So in the example above |
Queue Discipline | 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. |
