29.11 Configuring QoS for IP Packets

It is possible for IP networks to prioritize and differentiate between data packets transmitted through
routers across networks. This is useful because in data networks many different IP services like
email, voice, web pages, streaming video and music coexist within the same network infrastructure.
Prioritizing IP Data Packets
IP audio data packets can be configured for expedited or assured forwarding (Quality of Service, or
QoS) when traversing different networks. Routers can also be configured to ignore these forwarding
priorities, so they are not assured across all networks.
The codec can be configured to tag IP data packets sent across a network by entering a value into
the Differentiated Services Code Point (DSCP) field within the header of data packets transmitted
over the network. Check with your IT administrator before changing this setting. By default the codec
is configured for Assured Forwarding and more details about DSCP are available on Wikipedia at
http://en.wikipedia.org/wiki/Dscp.
