Section 3 - Conguration
QoS Engine
The QoS Engine option helps improve your network gaming performance by prioritizing applications. By default the QoS Engine settings are disabled and
application priority is not classied automatically. The QoS section contains a queuing mechanism, trac shaping and classication. It supports two kinds of
queuing mechanisms. Strict Priority Queue (SPQ) and Weighted Fair Queue (WFQ). SPQ will process trac based on trac priority. Queue1 has the highest
priority and Queue4 has the lowest priority. WFQ will process trac based on the queue weight. Users can congure each queue’s weight. The sum of all the
queues’ weight must be 100. When surng the Internet, the system will do trac shaping based on the uplink and downlink speed. The classication rules can
be used to classify trac to dierent queues, then SPQ or WFQ will do QoS based on the queue’s priority or weight.
The following parameters will be available for conguration:
Enable QoS: This option is disabled by default. Enable this option for better
performance and experience with online games and other
interactive applications, such as VoIP.
Uplink Speed: The speed at which data can be transferred from the router to
your ISP. This is determined by your ISP. ISP’s often dene speed
as a download/upload pair. For example, 1.5 Mbits/284 Kbits.
Using this example, you would enter 284. Alternatively you can
test your uplink speed with a service such as
www.dslreports.com.
Downlink Speed: The speed at which data can be transferred from the ISP to the
router. This is determined by your ISP. ISP’s often dene speed as
a download/upload pair. For example, 1.5 Mbits/284 Kbits.
Using this example, you would enter 1500. Alternatively you can
test your downlink speed with a service such as
www.dslreports.com.
Queue Type: Here the user can specify the queue type used. When choosing
the option Strict Priority Queue, the router will apply QoS based
on the internal specication for the queue ID’s listed. When
choosing the option Weight Fair Queue, the router will apply
QoS based on the user dened percentage in the Queue Weight
column.
Queue ID:
In this column the Queue ID used will be displayed.
Queue Priority:
In this column the Queue Priority used will be displayed.
Queue Weight:
After choosing to use the Weight Fair Queue option, under
Queue Type, the user will be able to manual enter the Queue
Weight for each individual Queue ID.
