ISO/IEC 29341-17-12:2011(E) describes the service type that enables modelling of the 'QosPolicyHolder' function capabilities. The functionality for the QosPolicyHolder Service can be implemented by any device on the network. The QosPolicyHolder Service is responsible for providing the traffic policy values for any given traffic stream as requested by an entity that manages the network traffic, typically a QoS Manager. The traffic policy values are determined by applying the policy rules, which are configured for the network, to the requested traffic information. This service definition is compliant with the UPnP Device Architecture version 1.0.
