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.
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, 1.5Mbits/284Kbits. 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, 1.5Mbits/284Kbits.
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.
