Multipath TCP (MPTCP) should perform better than single path TCP in non-shared bottleneck (NSB) links and have the same throughput in shared bottleneck links. The effort of MPTCP congestion control, which does not harm the single-path TCP, rather hinders the achievement of an ideal throughput in NSB links. In this paper, we propose a method to detect the bottleneck bottleneck-type of MPTCP connection, and accordingly propose BALIA for NSB (NSB-BALIA) to improve the throughput in NSB links. Through emulation evaluation, we confirmed that NSB-BALIA improved the throughput in the SB link without harming single-path TCP and achieved an ideal throughput ratio in the NSB links than that in the existing MPTCP congestion control algorithms.
