The effect of routing path buffer size on throughput of multipath TCP
Hyungjik Kim, Sunwoong Choi · 2016
Multipath TCP (MPTCP) is based on TCP and MPTCP transmits data through multiple paths. It is well known that MPTCP shows better throughput than single path TCP (SPTCP). In this paper, we investigate the effect of router buffer size on throughput of MPTCP. We observe that MPTCP, which uses Lowest-RTT-First scheduling algorithm and Opportunistic Linked-Increases Algorithm (OLIA), may show worse throughput than SPTCP when the router's buffer on transmission path of lowest RTT is small.
