Abstract In this paper, we put forward a scheme of realizing the source model to test the performance of switch fabric, and this it includes two kinds of source models. One, with the address happening suddenly, has balanced traffic and is used for designing the size of the buffer memory that the switch fabric needs. Another has non-balanced traffic and is used to verify the performance of the arbitration algorithm of the switch fabric. Simulation shows that this source model has satisfied the need of testing the performance of switch fabric and is useful for the research of switch fabric.
