Abstract:
We show, by measurements over a testbed and by mathematical analysis,
that the current MPTCP suffers from two problems: (P1) Upgrading some
TCP users to MPTCP can reduce the throughput of others without any
benefit to the upgraded users; and (P2) MPTCP users can be
excessively aggressive towards TCP users. We attribute these problems
to the "Linked Increases" Algorithm (LIA) of MPTCP [4], and more
specifically, to an excessive amount of traffic transmitted over
congested paths. Our results show that these problems are important
and can be mitigated. We believe that the design of the congestion
control of MPTCP should be improved.
