ISO/IEC 29341-17-11:20 11(E)描述了能够对“服务质量管理器”功能能力进行建模的服务类型。此服务为控制点提供了一种机制，用于: -以潜在的网络低效率为代价，不知道关于网络上的各种QoS设备的QoS能力和相关联的细节。 -抽象设置、修改和撤销与每个业务流相关联的QoS的任务。 -QosManager:3定义了用于设置参数化QoS的新能力。控制点现在可以请求对特定资源的预留，以供各个流的排他使用。成功的资源预留可确保流始终具有传输时间关键数据的带宽和其他资源。 -QosManager:3定义了用于控制点请求抢占UPnP上的现有预留的方法-QoS网络，如果需要允许新的流。 -QosManager:3支持向控制点提供阻塞流列表的机制，使得如果需要，控制点可以自己处理抢占。该服务定义符合UPnP设备架构1.0版。

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.
