Performance analysis of Multipath Transport layer schedulers under 5G/B5G hybrid networks

In this paper, we present a comprehensive analysis and comparison of several multipath schedulers under 5G/B5G hybrid networks. Specifically, we have developed a physical testbed and integrated nine different schedulers including schedulers from both multipath TCP (MPTCP) and multipath QUIC (MPQUIC) transport layer protocols. Our results present the systematic comparison of the schedulers under different packet loss ratio, bandwidth, delay, etc. Finally, we also present results to quantify the impact of bandwidth outages and fluctuations on the performance of the multipath transport layer schedulers. Additionally, we also present a systematic literature review (SLR) on multipath transport layer schedulers using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines to gather and analyse the information on the current state-of-the-art. One of the main contributions of the SLR is to broadly classify the research in the multipath transport domain into different categories and identify the key findings of the current published literature.
