5.3.5.5 Quality of Service (QoS)
Profile Network Configuration
The access point 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 that is applied to a packet.
