本文提出了一种基于并行多级互连网（ＭＩＮ）ＡＴＭ交换机的智能输入端口控制器，主要功能是为新到达的信元在并行多级互连网中寻找到一条能够成功建立连接的路径．目的是保证数据交换的正确性，降低信元在并行多级互连网中的阻塞概率，提高交换机的吞吐量 In this paper, an intelligent input port controller based on parallel multi-level interconnection (MIN) ATM switches is proposed. Its main function is to find a path for newly arrived cells in a parallel multi-level interconnection network to establish a connection successfully. The purpose is to ensure the correctness of data exchange, reduce the cell’s blocking probability in parallel multi-level Internet, and improve the throughput of the switch
