| 摘 要： | 传统的基于crossbar的输入排队交换结构在提供良好的QOS方面存在很大的不足，而CICQ（combined input and crosspoint buffered queuing）交换结构与传统的交换结构相比，不但能在各种输入流下提供接近输出排队的吞吐率，而且能提供良好的QoS支持。文章分析了CICQ结构的流控实现机制，讨论了基于信用的流控机制的开销和实现方案，对crosspoint缓存容鼍作了分析，给出了在各种存储器写入条件下，保持交换结构100％吞吐率所需的最小缓存容量。

| Abstract: | Traditional input-queued switches based on crossbar are insufficient in providing good QoS performance.As a contrast,the CICQ(combined input and crosspoint queuing) switches can provide almost 100% throughput under different input traffic,its performance is very closed to the OQ(output-queued) switch,and has the potentials to support good QoS.This paper analyzes the mechanism of flow-control,discusses the scheme for credit-based flow control,and analyzes the minimum buffer size in crosspoint required to realize 100% throughput. |

| Keywords: | CICQ switch Credit-based flow-control mechanism Crosspoint buffer size |
