Link: Differentiated Services
When you click the Differentiated Services link, the Differentiated Ser vices configuration screen
appears.
Differentiated Ser vices (Diffser v) allow your Gateway to make Quality of Ser vice (QoS) decisions about
what path Internet traffic, such as Voice over IP (VoIP), should travel across your network. For example, you
may want streaming video conferencing to use high quality, but more restrictive, connections, or, you might
want e-mail to use less restrictive, but less reliable, connections.
VDSL and Bonded ADSL models display this screen:
Most other models display this screen:
• To enable Differentiated Ser vices, check the Enable checkbox.
• (Not displayed on VDSL and Bonded ADSL models) Enter a value from 60 to 100 (percent) in the Low-
High Priority Ratio field. The default is 92.
Differentiated Ser vices uses the low-to-high priority queue ratio to regulate traffic flow. For example, to
provide the least possible latency and highest possible throughput for high priority traffic, you could set
the ratio to 100(%). This would cause the gateway to for ward low priority data only after the high priority
queue is completely empty. In practice, you should set it to something less than 100%, since the low pri-
ority traffic might have to wait too long to be passed, and consequently be subject to time-outs.
Click the Submit button.
You can then define Custom Flows. If your applications do not provide Quality of Ser vice (QoS) control, Cus-
tom Flows allows you to define streams for some protocols, por t ranges, and between specific end point
addresses.
