The Impact of Heterogeneous Propagation Delays on Multipath TCP Performance

In this paper we study the impact of heterogeneous round trip times on multipath TCP (MPTCP) performance via analysis the fluid model and simulation. Using parameter 'a' in MPTCP can alleviate poor performance due to divergent RTTs between paths. Moreover, divergent RTTs in MPTCP can affect response to changes in the network conditions.
