The uses different Quality of Service (QoS) screens to define WLAN and device radio QoS configurations. The
System Profiles > Network > QoS facility is separate from WLAN and radio QoS configurations, and is used to configure the
priority of the different DSCP packet types.
QoS values are required to provide priority of service to some packets over others. For example, VoIP packets get higher priority
than data packets to provide a better quality of service for high priority voice traffic.
The profile QoS screen maps the 6-bit Differentiated Service Code Point (DSCP) code points to the older 3-bit IP Precedent field
located in the Type of Service byte of an IP header. DSCP is a protocol for specifying and controlling network traffic by class so
that certain traffic types get precedence. DSCP specifies a specific per-hop behavior applied to a packet.
