• A de-blocking adaptive feedback control (AFC) design is proposed for shared-buffer CIOQ switching, achieving theoretical 100% non-blocking via a credit timeout detection mechanism (CTDM) that eliminates head-of-line blocking.
• The combination of VOQ dynamic regulation (VDRA) and threshold dynamic adaptive (TDAA) algorithms effectively mitigates congestion spreading from buffer overflow, enhancing system stability.
• Experimental results show a maximum throughput of 1499.66 Gb/s, minimum latency of 83 ns, effective throughput ratio of 96.94%, and packet loss rate as low as 0.6% under typical traffic.
• Compared to traditional CIOQ and IQ architectures, throughput improves by 15.12% and 20.55%, while forwarding latency is reduced by 26.9% and 54.7%, respectively, demonstrating superior performance for complex data exchange demands.
