Priority Queuing (TOS bit)
Motorola Netopia® Embedded Software Version 8.7.4 offers the ability to prioritize delay-sensitive data over the
WAN link on DSL connections.
WAN link on DSL connections.
Cer tain types of IP packets, such as voice or multimedia packets, are sensitive to latency introduced by the
network. This means that if such packets are not received rapidly, the quality of ser vice degrades. If you expect
to route significant amounts of such traffic you can configure your router to prioritize this type of traffic using the
priority queuing feature.
