Configuring QoS for IP Packets

24.14
It is possible for IP networks to prioritize and differentiate between data packets transmitted through
routers across networks. This is useful because in modern data networks many different IP services
like email, voice, web pages, video and streaming music coexist within the same network
infrastructure.
Prioritizing IP Data Packets when Broadcasting
IP audio data packets can be programmed for expedited or assured forwarding (Quality of Service or
QoS) when traversing different networks. Routers can also be programmed to ignore these
forwarding priorities so they are not assured across all networks.
The codec can be programmed 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. Check with your IT administrator before changing this setting. By default the codec is
programmed for Assured Forwarding and more details about DSCP are available on Wikipedia at
http://en.wikipedia.org/wiki/Dscp.
Configuring QoS DSCP

value already entered.
5. Next, use the numeric KEYPAD or onscreen keyboard to enter the new setting, then press the
button to save the new setting.
Important Note: To ensure the continuous and regular flow of tagged data packets along
the path from point-to-point, all routers and switching equipment must allow the QoS DSCP
setting. Any bandwidth partitioning schemes should partition over a small interval to ensure
the codec jitter buffer does not empty and audio remains continuous.
