4.3.4 QoS
Quality of Service (QoS) helps to prioritize data as it enters your router. By attaching special
identification marks or headers to incoming packets, QoS determines which queue the
packets enter, based on priority. This is useful when there are certain types of data you want
to give higher priority to, such as voice data packets given higher priority than Web data
packets.
The main goal of QoS is prioritizing incoming data, preventing data loss due to factors such
as jitter, delay and dropping. Another important aspect of QoS is ensuring that prioritizing
one data flow doesn’t interfere with other data flows.
QoS can be toggled Activated and Deactivated. QoS must be activated before you can edit
the following options. When you are done making changes, click on Add to save your
changes.
