# QoS Parameter Audience

This topic collection contains QoS parameter configuration information for two types of QoS users: QoS administrators and QoS clients.

QoS administrators are responsible for implementing a QoS queuing architecture by defining the scheduler profiles and referencing them from QoS profiles. QoS administrators also configure parameter definitions that control the parameters, interfaces, and ranges of values that QoS clients, using QoS parameters, can assign.

QoS clients are responsible for configuring services for individual subscribers by creating parameter instances. The parameter instances that QoS clients create depend on the settings that the QoS administrator defined in parameter definitions. QoS clients can use the CLI, Session and Resource Control (SRC), IP multicast bandwidth adjustment, RADIUS, or Service Manager to manage these services.
