Shiro ADSL 2/2+ Ethernet Modem QoS Shaper Configuration, HTB Low Latency Queue Discipline PRIOWRR

User Manual

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
	rate-based shaping algorithms.
HTB Queue	The hierarchical token bucket queue discipline is a rate-based shaping algorithm. This algorithm
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.
