Improving datacenter performance and robustness with multipath TCP

SIGCOMM 2011, Toronto, Canada · 2011

Abstract

The latest large-scale data centers offer higher aggregate bandwidth and robustness by creating multiple paths in the core of the network. To utilize this bandwidth requires different flows take different paths, which poses a challenge. In short, a single-path transport seems ill-suited to such networks. We propose using Multipath TCP as a replacement for TCP in such data centers, as it can effectively and seamlessly use available bandwidth, giving improved throughput and better fairness on many topologies. We investigate the reasons behind these benefits, teasing apart the contribution of each of the mechanisms used by MPTCP.
