This paper studies the effect of out-of-order packets on the MPTCP performance when using different access technologies, modelled to represent path diversity in terms of delay and reliability. The study identifies trade-offs between different CC algorithms in terms of aggregate throughput gain when different packet reordering recovery solutions being implemented. Our analysis shows that TCP-DOOR performs best with both coupling and uncoupling controllers, while DSACK outperforms others under fully coupled. However F-RTO provides better application throughput particular with uncoupled controller and has lower memory requirements compared to others. Adding to that, our observations show that MPTCP suffers from reordering problem and needs a suitable recovery method to achieve optimal aggregate throughput.
