6.8.1 ToS (Type of Service) and WMM QoS
ToS defines the DS (Differentiated Service) field in the IP packet header. The ToS value of
outgoing packets is between 0 and 255. 0 is the lowest priority.
WMM QoS checks the ToS in the header of transmitted data packets. It gives the application a
priority according to this number. If the ToS is not specified, then transmitted data is treated as
normal or best-effort traffic.
Click Network > Wireless LAN > QoS. The following screen displays.
