“Network quality” setting (IP networks)
Depending on the quality of service provided on the IP network, especially its jitter performance, it is
possible to change the stability/latency compromise used by the ScoopTeam. For this purpose, a
“
Network Quality
” setting is available among the settings of the network interface (example for the
primary Ethernet interface: sub-menu
Network
/
LAN1 settings
). Five choices are proposed:
“Very High”:
suitable for a very good quality network, with very low jitter and packet loss
rate; latency is the smallest, but the codec will be very sensitive to possible jitter.
“High”:
suitable for a good quality and low jitter network; latency is minimal, but the
codec will have little tolerance to possible jitter.
“Middle”:
intermediate (and default) setting, suitable for a moderate transmission jitter.
“Low”:
to be preferred when the network has low QoS, especially for residential ADSL
lines. This setting ensures a safer operation, at the cost of a high latency.
“Bad”:
to be used when the network is very disturbed, e.g. on mobile networks. The
latency is significantly higher than the above setting.
“Very Bad”:
to be used in worst case, very poor quality mobile networks. This choice also
gives the highest latency.
On a LAN and/or private network with a controlled quality, the “Very High” quality setting is
recommended, as it yields minimum latency.
On the contrary, it should be avoided for a link via the Internet, as it can only tolerate a low jitter. One
solution can be to start with a “Middle” setting, and move to the “Low” setting, or further, if too much
audio disturbance is heard.
This parameter is interface-specific, i.e. a different choice can be set for each network interface.
