Treat All

Today’s networks support applications that deliver text, audio, images and video, often in real time and with a high degree of interactivity, using a common infrastructure. More often than not, traffic is carried over packet-switched networks that treat all data the same, under what is known as best-effort service. Packet switching can achieve very high efficiency through statistical multiplexing of data from numerous sources; however, due to the very nature of packet switching, one should expect fluctuations in throughput, delay, reliability, etc., for any given flow. The greater the statistical multiplexing capabilities, the greater the efficiency and also the greater the variability of achieved performance; in this sense, best-effort service provides maximum efficiency with highly unpredictable service quality. Clearly, not all traffic flows are created equal. Interactive web-based applications tend to be very sensitive to throughput, while real-time voice and video are sensitive to delay and jitter, and traditional data applications such as e-mail and file transfers are fairly insensitive to fluctuations in performance. The concept of quality of service (QoS) has evolved from the realization that in networks that carry heterogeneous traffic it makes sense to treat specific classes of traffic according to their specific needs.

Purpose – The purpose of this paper is to examine quality of service experience as reported by tourists in seven northern and southern Mediterranean cities. Design/methodology/approach – A self-report study was used to gather data from 1,362 tourists. Once validity of Otto and Ritchie’s (1996) scale had been confirmed, ANOVA and the non-parametric Kruskal-Wallis test were used to analyse the data. Findings – Tourists in all destinations highlighted the importance of the dimension peace of mind. Significant differences between tourists in the northern Mediterranean and those in the southern Mediterranean were observed in two quality of service experience dimensions: hedonics and involvement. Research limitations/implications – Although the sample was large, this study’s scope was limited to seven Mediterranean tourist cities. Further research is therefore required to generalize findings to other Mediterranean tourist destinations. Practical implications – Knowledge about quality of service experience dimensions may help tourism managers innovate and improve services. Tourists perceive northern Mediterranean destinations differently from destinations in the southern Mediterranean. Tourists report high tourist involvement in northern destinations, whereas in the south, tourists emphasize destinations’ hedonic features. These implications are also valuable for European policymakers. Originality/value – The study compared quality of service experience in northern and southern Mediterranean tourist destinations. To do so, it analysed a sample of 1,362 tourists from seven Mediterranean cities. This research is the first to analyse quality of service experience in the Mediterranean.
