QoS (Quality of Service)
Many communication and multimedia applications require high speed and large band-
widths to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection with limited capacity available.
QoS (Quality of Service) divides this capacity between the different applications and
provides undelayed, continuous data transfer where data packets with higher priority
are given transmission preference.
ì
In the Advanced Settings – Internet menu, select the entry QoS.
ì
Activate Differentiated services, i.e. the prioritisation of certain services for data
transfer between your network and the Internet.
ì
In the field next to Upstream rate, enter the value for your DSL connection. The
value is determined in the contract with your Internet provider
You can determine via Priority which data packets are to be given preferential transmis-
sion. With the aid of PHB (Per Hop Behaviours) a decision is also made about whether
data packets are to be forwarded immediately before all others (EF, Expedited Forward-
ing), guaranteed and without data loss (AF, Assured Forwarding) or normally (BE, Best
Effort). If your application already supports QoS your application will determine the pri-
ority automatically, and this will be noted by your device for forwarding. In addition,
your device recognises certain Predefined applications and gives each data packet the
relevant priority. You can also determine which proportion of the bandwidth for your
Internet connection is to be made available for a certain class as Allocated bandwidth.
ì
Select the Allocated bandwidth for the Predefined applications and for the line
(all other applications).
ì
Click on OK to save and apply the changes.
