Creating Service Flows - Overview 
There are four steps associated with creating service flows: 
Note: A service class can not be deleted until all provisioned/active service flows 
referencing this service class have been deleted. 
1.  Create service class. 
Each service class defines a set of QoS parameters that can be associated with a 
service flow. Multiple service class definitions can be added to create a library of 
service classes. By creating a set of standardized service classes, new service flows 
can be added that conform to pre-defined service level agreements (SLAs). Each 
service class definition includes traffic rates, latency settings, priority, and 
transmission policy settings. 
2.  Create service flow. 
All service flows are based on existing service class definitions. Separate service 
flows are required for downlink and uplink traffic. Each definition requires 
identifying the subscriber, flow direction, class of service, and the classifier type. 
3. Define 
classifier. 
A unique set of classifier rules can be defined for each service flow, depending on the 
classification type (i.e., Packet, 802.3/Ethernet) selected when the service flow is 
created. All associated classifiers are deleted when the service flow is deleted. 
4. Activate 
A new service flow is not activated until a classifier is assigned (click  
Add
   in the 
Classifier
 screen). 
If the target subscriber is registered a Dynamic Addition Session (DSA) session is 
initiated. During a DSA session, the service flow is in Requesting state. If the DSA 
session is successful, the state is set to 
Active
. If the DSA session is not successful, the 
state is set to 
Rejected
If the target subscriber is not registered, the service flow request is stored until the 
associated subscriber is registered. The subscriber registration triggers the activation 
of all associated service flows.
