提出了一种用于测试交换结构性能的仿真信源的实现方案，其内容包含两种形式的交换结构信源：一种是均衡业务下的具有地址突发的信源，用于验证交换结构所需的缓存大小；另一种是非均衡的业务源，用于验证交换结构的仲裁算法的性能。经仿真证实，此模型能很好地满足测试交换结构性能的需要，有助于交换结构的研究。关 键 词 自相似; 信源模型; 突发; 交换结构；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.Key words self-similarity; source model; burst; switch fabric
