Abstract
The majority of networking devices currently available are equipped with a few communication interfaces. However, the design of the fundamental transport protocol – TCP – prohibits using them simultaneously. Recently, a variant of TCP – Multipath TCP (MPTCP) – that allows for parallel transmission over different paths has been developed. The protocol itself does not define any particular way of splitting the application data stream. Taking into account the proliferation of mobile terminals, a good quality indicator is the amount of energy dissipated by the communicating device. The previous works in the field assume that the paths established by the MPTCP stack are independent. This paper discusses the theoretical and practical aspects of stream splitting when the paths influence each other through a common bottleneck. A comparison with the reference solution is provided. The tests conducted in the public networking environment show a substantial improvement in energy economy.
