Abstract (in Japanese) (See Japanese page) 
(in English) The currently implemented MPTCP has a problem that the throughput decreases compared to normal TCP in an environment where the network delay difference between the interfaces is large. Besides the delay difference between the interfaces, there is a delay difference in the uplink/downlink direction in the interface such as LTE. In the existing research, due to scheduling based on RTT of each pass, out-of-order occurs on the receiver side in an environment with uplink/downlink delay difference. In addition, since scheduling is performed considering only the tail packet, out-of-order occurs at the time of transmission of an intermediate packet. Therefore, in this research, one-way latency information is used instead of RTT, and it corresponds to an environment with uplink/downlink delay difference. We also propose a scheduler that considers out-of-order of packets other than tail packets.As a result of the evaluation, throughput improvement of up to 8.44% was observed for large volume data. Moreover, it showed that downloading time of small capacity data is shortened in environment with vertical delay difference.
