Abstract

Testing PABXs and call centers under high load is of paramount importance because customers rely on these systems for safety and business critical applications. A traffic generator for high traffic volumes is presented in this paper. The two key characteristics of the traffic generator are the generation of traffic with configurable statistical properties and its flexibility in many aspects, ranging from the number and kind of emulated users to the user behaviour models and signalling protocols. This extraordinary flexibility could only be achieved by a pure software approach. The architecture clearly separates the basic runtime system and support functions which are implemented in the traffic generator core from user models and signalling protocols which the traffic generator reads and executes during tests.
