Advanced > QoS
Quality of Service offers a defined level of performance in a data communications system - for
example the ability to guarantee that voice traffic is given priority over other network traffic to
ensure that conversations are not disrupted by other network requirements. This means that should
you be talking via the VoIP facility and someone else in the house starts downloading a big file, the
download won't disrupt the flow of voice data.
QoS controls allow you to assign priority to different data types according to their TOS flag.
