This paper presents a new approach to test the performance of communication network components such as protocols, services, and applications under normal and overload situations. Performance testing identifies performance levels of the network components for ranges of parameter settings and assesses the measured performance. A performance test suite describes precisely the performance characteristics that have to be measured and procedures how to execute the measurements. In addition, the performance test configuration including the configuration of the network component, the configuration of the network, and the network load characteristics is described. PerfTTCN — an extension of TTCN — is a formalism to describe performance tests in an understandable, unambiguous and reusable way with the benefit to make performance test results comparable. First results on the description and execution of performance tests will be presented.
