| 摘 要： | 日前广泛使用的交换机采用输出队列结构，系统可扩展性差、通信速度有限等缺点。文章提出一种基于输入队列的新型交换机结构，通过采用双口存储器来实现交换机的输入缓冲区，通过多数据包查询技术来提高交换机的通信性能。分析结果表明：文章设计的交换机系统吞吐量可达到理论吞吐量的95．748％．接近于输出队列交换机，但需要的存储器带宽只有输出队列交换机的1/N为交换机的端口数），大大提高了系统的可扩展性。

| Abstract: | The most popular switch is based on output queue architecture now, which has the disadvantage of the high complexity and low expansibility. The paper put forwards a new switch architecture based on input queue, where we use double-port memory to implement input queue. By the technology of muti-queuy-data-packet, the switch performance is improved. The analysis result appears: the throughput of the new switch can attain 95.748%, which is near to that of output queue switch, and the demand bandwidth of memory in new switch is the 1/N of that of output queue switch. So the new switch has better expansibility and lower complexity. |
