Achieving multipath transport and getting more network throughput by using multiple interfaces of multi-homed device is a hot topic in Internet protocol. MPTCP is a mature and key protocol for multipath transmission, also in the focus of the IETF. This article presents the behaviors of MPTCP multipath transmission in the local test-bed scenario, Internet scenario and Nor Net test-bed scenario. Results show that MPTCP protocols can significantly increase throughput. Meanwhile its path management and scheduli...
