Abstract:
Recently, the Multipath Transmission Control Protocol (MPTCP) comes to be used widely. It allows more than one TCP connections via different paths to compose one Multipath TCP communication. Our previous papers pointed out that insufficient send socket buffer makes the throughput worse than that of single path TCP, when the subflows have different transmission delays. Although our previous papers gave the detailed analysis on the throughput degradation focusing on the relationship between the send socket buffer size and the delay, they did not clarify the reason of the throughput degradation. This paper investigates the Linux MPTCP software and the MPTCP communication details, and clarifies why the insufficient socket buffer degrades the MPTCP throughput.
