PERFORMANCE TESTING ARCHITECTURE FOR COMMUNICATION PROTOCOLS

This paper presents a new model for distributed and parallel performance testing. The model has been designed to support testing based on language Testing and Test Control Notation version 3 (TTCN-3). Our test environment is capable of generating a realistic load towards the tested implementation with a large number of distributed parallel tester processes. The architecture is also able to operate on test systems with heterogeneous hardware and operating systems. We show the components of our model in details and demonstrate their operation and internal communication on examples. The practical issues of the test system implementation are also discussed. Some results from real life performance testing applications conclude the paper.
