1.3.4.9 Assigning Service Levels

Service levels are assigned in the individual SS configuration files, allowing for max-

imum flexibility in differentiating services among subscribers.

To define the Service flows for a subscriber, EMS lets the user choose a Default Ser-

vice flow. This is done by choosing the Add Default Classifier button. The WiMAX

standard will drop any packet that does not meet any Classifier rule. So if the users

do not want to define specific Classifier rules for each type of traffic pattern, then they

can choose a Service Flow as the Default Service flow by adding a Default Classifier

for that Flow. Only 1 Default Service Flow should be defined for each direction, i.e.

one for the Upstream and another one for the Downstream.
