异构网络中基于最小传输时间估计的MPQUIC路径调度
MPQUIC Path Scheduling Based on Minimum Transmission Time Estimation in Heterogeneous Networks
摘要
Abstract
With the development of 5G and future 6G networks,communication demands are continuously increasing,driving higher expecta-tions for network reliability,throughput,and latency.In heterogeneous network environments,different types of networks(such as ground 5G networks,satellite networks,Wi-Fi,etc.)can collaborate to provide broader coverage and flexible resource scheduling.In this background,this paper proposes a muti-path scheduling algorithm based on Minimum Transmission Time Estimation(MTTE),applied to the Multipath Quick UDP Internet Connections(MPQUIC)protocol,to enhance data transmission performance in heterogeneous network environments.Ex-isting MPQUIC path scheduling algorithms struggle to fully exploit the bandwidth potential of dynamic and heterogeneous network links,lead-ing to suboptimal throughput and overall performance.To address this issue,the proposed algorithm estimates the transmission time for each path during data packet allocation and reduces the differences of transmission time among the paths to alleviate Head-of-Line(HoL)block-ing,ultimately minimizing the overall transmission time.Unlike other scheduling algorithms that allocate all data packets to the best-perform-ing path,the proposed algorithm fully leverages the bandwidth resources of heterogeneous paths to enhance overall network transmission per-formance.We simulate the data transmission tasks under various network environments using NS-3 network simulator.The experimental re-sults show that the proposed algorithm improves the throughput by approximately 9.8％and reduces the file transmission completion time by about 11.3％on average compared to baseline algorithms.关键词
