Abstract :
To enforce SLA management, SLA metrics and quality assessment method for network services or application services are required. In this paper two metrics for Web application service intrinsic performance, average round-trip time and delivery speed are defined taking both implementation mechanism of Web applications and user access behavior into account. In three cases, Web traffic traces for a specific Web site were recorded at client-side to calculate above two metrics; meanwhile the user-perceived service qualities of the Web site were evaluated subjectively. Linear regress analysis of the observation data shows that user-perceived quality of Web application service can be objectively estimated by a linear regression function that uses the two metrics as independent variables.
