In recent years, more and more wireless devices are equipped with multiple communication interfaces. From the perspective of increasing communication capacity and stability through effective use of frequencies, multi-path communication technology using multiple interfaces simultaneously has been attracting attention. Multi-Path TCP (MPTCP), which is an extension of TCP/IP protocol widely used today, has been studied extensively worldwide. We implemented the MPTCP specification in ns-3, an open-source network simulator, and evaluated its behavior by comparing its performance with that of a Linux PC. As a result, we found that our simulator behaves similarly to Linux PC in an environment without packet loss. On the other hand, when there is packet loss, the behavior of the simulator is different from that of Linux PC. This paper reports our simulation environment and evaluation results.
