We attribute these problems to the "Linked Increases" Algorithm (LIA) of MPTCP {[}4{]}, and more specifically, to an excessive amount of traffic transmitted over congested paths. Our results show that these problems are important and can be mitigated. We believe that the design of the congestion control of MPTCP should be improved.}, }
