  Abstract

This paper proposes a new congestion control algorithm, Dynamic Bandwidth Aware Congestion Control (DBAC), to enhance data transmission efficiency in modern network environments that require the use of multiple paths. Traditional single-path TCP has limitations that are addressed by Multipath TCP (MPTCP), which can utilize multiple paths simultaneously to maximize bandwidth and improve transmission reliability. However, MPTCP suffers performance degradation in high-speed, long-distance networks due to path characteristic asymmetry. To overcome this, DBAC combines TCP CUBIC for paths with high BDP and LIA for regular paths, optimizing resource utilization and fairness. Experimental results show that DBAC significantly improves resource utilization and transmission performance, effectively using over 80% of the bandwidth on high BDP paths, compared to less than 20% with traditional LIA.
