One subnet for 1 MPTCP subflow. Two MPTCP subflows are established for data transmission. Iperf is used for data transmission at application layer. \r\n\r\nHowever, overall throughput of mptcp is not as good as single tcp. Moreover, mptcp throughput is not stable, ranging from 250mbps to 550mbps (average throughput for a 30-second iperf test). \r\n\r\nThus, I have two questions: 1) why mptcp throughput is not stable; 2) in what case, mptcp throughput is not as good as regular tcp thoughput. Thank you!\r\n"}}
