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 available with limited capacity.
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
Select Differentiated services, i.e. the priorisation of certain services for data trans-
fer between your network and the Internet.
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 rel-
evant priority. You can also determine which proportion of the bandwidth for your Inter-
net 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).
