Design of Cross-Layer Optimal Transmission Control Algorithm in Low Latency Networks

In this paper, a cross-layer optimal transmission control algorithm for low latency networks is proposed, a multilevel parameter acquisition architecture and a link quality assessment method based on fuzzy logic are designed, and a lightweight event-driven cross-layer information interaction framework is constructed. Based on this, the congestion warning index and multi-level adaptive rate adjustment algorithm are developed to achieve multi-objective joint optimisation of throughput, delay and stability. Experimental validation shows that the algorithm significantly reduces end-to-end delay and jitter, improves throughput and fairness, and especially exhibits fast parameter adjustment capability in dynamically changing network environments, which provides efficient transmission guarantee for diverse low-latency applications.
