Observing real Multipath TCP traffic

Wed, 02/17/2016 - 13:36 by Viet-Hoang Tran

Abstract

Multipath TCP is a recent TCP extension that enables multihomed hosts like
smartphones to send and receive data over multiple interfaces. Despite the
growing interest in this new extension, little is known about its behavior in
real networks. We analyze a five-month trace collected on multipath-tcp.org
using Multipath TCP. This first detailed study of real Multipath TCP traffic
reveals several interesting points about its behavior in the wild. With packets
from thousands of hosts using IPv4 and/or IPv6, we confirm that Multipath
TCP correctly passes through a wide range of Internet paths. We observe long
Multipath TCP connections that benefit from handovers and also connections
composed of subflows having very different round-trip-times. We also analyze
some inefficiencies in the current Multipath TCP implementations and quantify
the importance of reinjections, i.e. the transmission of the same data over two
or more subflows.
