“Multipath TCP, as proposed by the IETF working group
mptcp, allows a single data stream to be split across
multiple paths. This has obvious benefits for reliability,
and it can also lead to more efficient use of networked
resources. We describe the design of a multipath congestion control algorithm, we implement it in Linux,
and we evaluate it for multihomed servers, data centers
and mobile clients. We show that some ‘obvious’ solutions for multipath congestion control can be harmful,
but that our algorithm improves throughput and fairness
compared to single-path TCP. Our algorithm is a drop-in
replacement for TCP, and we believe it is safe to deploy.”
