【 摘 要 】

As the number of Web users and thediversity of Web applications continues to explode,Web Quality of Service (QoS) is an increasingly critical issue in thedomain of e-Commerce. This paper presents experiments designed to estimate users' tolerance of QoS in thecontext of e-commerce. In addition to objective measures we discuss contextual factors that influence thesethresholds and show how users' conceptual models of Web tasks affect their expectations. We then show how userthresholds of tolerance can be taken into account when designing web servers. This integration of userrequirements for QoS into systems design is ultimately of benefit to all stakeholders in the design of Internetservices.15 Pages
