Quality of Service (QoS) is a quality attribute sub-concept that represents those quality attributes that can be measured objectively or they are unmeasurable but can take objective values. For example, security attributes are QoS attributes but cannot be measured. However, the values that they take are objective. QoS attributes are typical constituents of SLAs (e.g response time and availability).[CD-JRA-1.3.3] | The quality of service (QoS) refers to several related aspects of telephony and computer networks that allow the transport of traffic with special requirements.
