multipath TCP (MP-TCP) allows the use of multiple paths between two end hosts for a single data transmission, extending the capabilities of SinglePath Transmission control Protocol (SP-TCP). aimd congestion control algorithm can be implemented on each subpath of the MP-TCP sender. However, the characteristics of the aimd-type windowflowcontrol depend on the control parameters (alpha, beta). There have been some guidelines proposed to select proper control parameters (alpha, beta) that can achieve fair bandwidth sharing between SP-TCP and MP-TCP senders using existing MP-TCP congestion algorithms. However, current guidelines do not offer a solution that can simultaneously increase the throughput of an MP-TCP sender and ensure fairness between MP-TCP and SP-TCP senders. To address this issue, this study proposes a control parameter setting for an MP-TCP sender that can maximize the sender's throughput and ensure fairness between SP-TCP and MP-TCP senders. We derive a fluid model of a network that includes SP-TCP and MP-TCP senders, describing the relationship between control parameters, the aggregate throughput of an MP-TCP sender, and the packet loss rate of a router.
