Thanks for the hint. Sadly and as often the case this term is used with multiple meanings in different contexts, see e.g. the QoS definitions of the MQTT protocol: http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/MQTT_V3.1_Protocol_Specific.pdf I don't know where the term first originated from but I agree it's best to avoid confusion. So maybe "delivery guarantees" or "reliability level" might be better words.
