METHOD, SYSTEM AND COMPUTER PROGRAM PRODUCT FOR EVALUATING DOWNLOAD PERFORMANCE OF WEB PAGES

摘要

Download performance parameters of web pages accessible via a network (N) are evaluated by providing at least one model (20) for predicting a set of download performance parameters for said web pages as a function of a respective set of input parameters. The at least one model includes at least one optimisation parameter (lambda). A set (18) of sample web pages is defined and said set of download performance parameters for the sample web pages (18) are both measured (14, 18) and evaluated on the basis of the model (20) for different values of the at least one optimisation parameter (lambda). An error indicative of the difference between the download performance parameters for the sample web pages (18) as measured (14, 18) and as evaluated on the basis of said model (20), respectively, is defined and an optimised model is selected including a value of the least one optimisation parameter (lambda) minimising the error or reducing it below a predetermined value. Download performance parameters for any selected set of pages accessible through the network (N) can then be evaluated without interfering with operation of the network on the basis of the optimised model.
