Figure 3: Testbed Architecture
In this section, we describe the design of a new method to generate Web traffic. This method addresses the problems raised in the previous section. It should be noted that our work does not by itself address the problem of accurate simulation of Web workloads in terms of the request file types, transfer sizes and locality of reference in URLs requested; instead, we concentrate on mechanisms for generating heavy concurrent traffic that has a temporal behavior similar to that of real Web traffic. Our work is intended to complement the existing work done on Web workload characterization [5, 6, 7, 23, 31], and can easily be used in conjunction with it.
