Abstract: |
The
paper deals with the problem of modeling key features of the Web traffic
generated by Internet bots, observed at the input of a Web server. Based on
real log data of an online store, a set of bot
sessions was prepared and analyzed. Three session features connected with
bots’ arrival process at the server were analyzed: session interarrival time, request interarrival
time, and the number of requests in session. Distributional models for these bot session features were developed using regression
analysis and validated through graphical comparisons of histograms for the
empirical data and simulated values. As a result, interarrival
times of bot sessions and interarrival
times of requests in bot sessions were modeled by a
Weibull and a Pareto distribution, respectively,
and the numbers of requests in session were modeled by a function being a
combination of a sigmoid and exponential distributions. The aim of our
analysis was to develop a model of a session-based bot
arrival process on a Web server which may be then
implemented in a bot traffic generator
integrated with a Web server simulator. |
