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
queue’s 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. An ISP often
denes 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 IDs 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.
