Quality of service is important for real-time streaming multimedia applications such as voice over IP, multiplayer online games and IPTV, since these often require fixed bit rate and are delay sensitive.

Service quality (SQ), in its contemporary conceptualisation, is a comparison of perceived expectations (E) of a service with perceived performance (P), giving rise to the equation SQ = P − E. [1] This conceptualistion of service quality has its origins in the expectancy-disconfirmation paradigm.
This approach conceptualizes service quality as a gap between consumer's expectations of a forthcoming service encounter and their actual perceptions of that encounter. [102] Accordingly, service quality can be represented by the equation: [103] SQ = P − E. where SQ is service quality P is the individual's perceptions of given service delivery
When perceptions exceed expectations then service quality is high. The model of service quality identifies five gaps that may cause customers to experience poor service quality. In this model, gap 5 is the service quality gap and is the only gap that can be directly measured. In other words, the SERVQUAL instrument was specifically designed to ...

All of the factors above, coupled with user requirements and user perceptions, play a role in determining the perceived 'fastness' or utility, of a network connection. The relationship between throughput, latency, and user experience is most aptly understood in the context of a shared network medium, and as a scheduling problem.
Serviceability involves the consumer's ease of obtaining repair service (example: access to service centers and/or ease of self-service), the responsiveness of service personnel (example: ease of getting an appointment, willingness of repair personnel to listen to the customer), and the reliability of service (example: whether the service is ...
