# QoS Audience

This topic collection contains 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 drop profiles, queue profiles, scheduler profiles, QoS profiles, and QoS parameter definitions.

QoS clients are responsible for configuring services for individual subscribers by creating parameter instances. The parameter instances that QoS clients can create depend on the settings defined in parameter definitions by the QoS administrator.
