In performance testing of ATM switches and network of switches a variety of connection configurations is needed. In most of the cases, these configurations require one traffic generator and/or analyzer for each switch port. Since this equipment is rather expensive, it is desirable to define scalable configurations that can be used with a limited number of generators. In this paper we present a methodology for the implementation of scalable connection configurations. The methodology is simple and offers a general solution to generate scalable connection configurations. Several examples of scalable configurations illustrate the methodology. The application of this methodology helps users to repeat easily performance tests under the same traffic load conditions.
