The present document discusses Quality of Service (QoS) aspects of services related to the Internet of Things (IoT) ecosystem from an end-to-end perspective; a strict end-user, service-oriented point of view. Here, end-to-end is understood as "from a service user/terminal/provider to a service user/terminal/provider".

The discussion deals with two questions. The first question is if the existing framework for QoS parameter definitions and methodologies is sufficient to also include the IoT angle of view. The second question is if the existing portfolio of QoS parameters needs extensions or adaptations.
