QoS guarantees are important if the network capacity is insufficient, especially for
real-time streaming multimedia applications such as voice over IP, online games,
and IPTV, since these applications are delay sensitive and often require a fixed bit
rate.
This section describes how to configure the WAN, LAN, and WLAN QoS. It
includes the following topics:
• General QoS Settings, page 141
• Configuring the WAN QoS, page 141
• Configuring the LAN QoS, page 147
