Description (English):

ISO/IEC 29341-17-11:2011(E) describes the service-type that enables modelling of 'Quality of Service Manager' function capabilities. This service provides a mechanism for a Control Point to: - Be agnostic of the QoS capabilities and associated details about the various QoS Devices on the network at the expense of potential network inefficiency. - Abstract the tasks of setting up, modifying and revoking the QoS associated with every traffic stream. - QosManager:3 defines new capabilities to set up Parameterized QoS. Control Points may now request reservations for specific resources for the exclusive use of individual streams. Successful resource reservation ensures that streams will always have the bandwidth and other resources to transport time critical data. - QosManager:3 defines a method for Control Points to request preemption of existing reservations on the UPnP-QoS network if necessary to admit a new stream. - QosManager:3 supports a mechanism for providing a list of blocking streams to a Control Point so that it can handle preemption on its own, if desired. This service definition is compliant with the UPnP Device Architecture version 1.0.

Abstract

Overview

ISO/IEC 29341-17-11:2011 defines the UPnP Quality of Service (QoS) Manager Service (QosManager:3) as part of the UPnP Device Architecture. The standard specifies the service-type and control protocol that enable a Control Point to request, update and release QoS for traffic streams on a UPnP network. It is compliant with the UPnP Device Architecture version 1.0 and describes how a QoS Manager mediates between Control Points and network QoS-capable devices (QosDevice and QosPolicyHolder services).

Key topics and technical requirements

Service modelling and XML service description: State variables, actions and eventing are defined in XML fragments so the service can be discovered and invoked by UPnP Control Points.
Parameterized QoS reservations (QosManager:3): Control Points may request resource reservations (bandwidth and other resources) for individual streams to ensure time-critical transport.
Preemption and blocking-stream lists: Methods to request preemption of existing reservations and mechanisms to obtain lists of blocking streams so Control Points can perform preemption handling if desired.
Core actions and interfaces: Actions such as RequestTrafficQos(), UpdateTrafficQos(), ReleaseTrafficQos(), BrowseAllTrafficDescriptors(), GetQmCapabilities(), RequestExtendedTrafficQos(), and UpdateExtendedTrafficQos() are defined with arguments and error codes.
State variables and traffic descriptors: Detailed types for TrafficDescriptor, TrafficHandle, QoS capabilities and extended QoS information, plus rules for which elements can be updated.
Eventing, moderation and error handling: Event model and common error codes are specified; normative and informative annexes provide traffic descriptor matrices, candidate preemption methods and ContentDirectory integration.
Conformance and testing: The document includes test definitions and normative annexes to support interoperability.

Practical applications and who uses it

Media streaming systems: Ensure consistent bandwidth and latency for audio/video streams across UPnP-enabled home or enterprise networks.
Real-time communications: Support VoIP, video conferencing and time-sensitive sensor data by reserving resources per-stream.
Network management and home gateway vendors: Implement QosManager service in gateways, routers and multimedia servers to centralize QoS control.
Software developers and integrators: Build UPnP Control Points that are QoS-aware without requiring device-specific logic, leveraging the abstracted QoS Manager API.
Test labs and certification bodies: Use defined tests and XML service descriptions to verify interoperability between QosManager, QosDevice and QosPolicyHolder implementations.
