Multi-path transport protocols provide increased throughput or reliability, by utilizing these interfaces simultaneously. However, multi-path transmission over networks with very different QoS characteristics is a challenge. In this paper, we studied Multi-Path TCP~(MPTCP) in heterogeneous networks, specifically MBB networks and WLAN. We first investigate the effect of bufferbloat in MBB on MPTCP performance. Then, we propose a bufferbloat mitigation algorithm: Multi-Path Transport Bufferbloat Mitigation~(MPT-BM). Using our algorithm, we conduct experiments in real operational networks. The experimental results show that MPT-BM outperforms the current MPTCP implementation by increasing the application goodput quality and decreasing MPTCP's buffer delay, jitter and buffer space requirements.}", url = "https://www.simula.no/file/simulasimula2722pdf/download", url.size = "839259", url.md5 = "41fdb83e1fa929ad9523504ea7b43402", url.mime = "application/pdf", url.pagesize = "595.276 x 841.89 pts (A4)", url.checked = "2014-12-12 18:14:47 CET" }
