ISO/IEC 29341-17-10:2011

Information technology - UPnP Device Architecture - Part 17-10: Quality of Service Device Control Protocol - Level 3 - Quality of Service Device Service

ISO/IEC 29341-17-10:2011(E) describes the service definition which is compliant with the UPnP Device Architecture version 1.0.[DEVICE]. This service-type enables modeling of the 'QosDevice' function capabilities. The QosDevice:3 Service is a function typically implemented in source, sink and intermediate network. The QosDevice Service is responsible for providing the appropriate network resources to traffic streams and information about the state of the device as requested by the QosManager as defined in the QosManager:3 Service.
