SB5101 Cable Modem Overview
DOCSIS 1.1 introduced the idea of Service Flows with individual QoS levels so that an operator
can distinguish between the QoS requirements of different types of end user service and allocate
the resources required to ensure the customer actually receives the service they are paying for.
Beachcomber allows the definition of both the upstream and downstream service flows and the
classifiers which determine the admission to those flows, the graphical presentation makes it easy
to see what is being configured and to compare the details of different configurations.
