The last trends at communications realms, in particular, wireless technologies, where it is more and more usual that devices carry more than one interface (i.e. multi-Radio Access Technology (RAT)), to get access to the Internet, question the classic single-path paradigm, imposed by the mainstream transport protocol, TCP. In this paper, the authors assess the behavior of MultiPath TCP (MPTCP), which allows the transparent breakdown of a single TCP session into multiple simultaneous subflows. This straightforward feature might lead to remarkable performance enhancements, yielding as well a stronger resilience against failures within any of the routes.
