| Abstract | The criticity of the Internet keeps increasing with a very high number of services depending on its infrastructure. The Internet is expected to support services with an increasing tangible impact on the physical world such as the Internet of Things (IoT) or autonomous vehicles. It is thus important to address the current infrastructure shortcomings in terms of scalability, confidentiality and reliability. Multipath communications are one possible solution to address this challenge. The transition towards multipath technologies is not obvious, there are several challenges ahead. Some network devices block unknown protocols, thus preventing the emergence of new technologies, which plays a part in what is often referred to as the ossification of the Internet. Moreover, due to technical reasons, there are cases for which multipath technologies perform worse than their single path counterpart. In this thesis, we are interested in addressing some of these cases and limit their impact, so that multipath communications perform better than single path communications as often as possible. More specifically, we propose enhancements to Multipath TCP (MPTCP). After a detailed survey of multipath communications across all layers, we propose an answer as to the question of how many paths to use and how to ensure proper forwarding. Moreover, motivated by the intuition that packet arrival disorder can be mitigated by the knowledge of one way latencies, we propose a latency estimator with sender-side modifications only. Furthermore, as throughput maximization is in general solved regardless of the interface cost or user preferences, we elaborate a framework capable of presenting more complex strategies if for instance the user wants to enforce throughput even on less efficient paths. Finally, we develop and present a complete simulation model of MPTCP. |
