Section 3 - Software 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.

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.
