Strategic path diversity exploitation across Internet layers

We present in this thesis novel routing protocols able to take into consideration strategic aspects when deciding which path among many to take, and that at the Internet communication network scale. The standpoint adopted in this study is that novel routing architectures are exposing a higher path diversity to networks and applications so that networks and applications can be made capable to more intelligently select their strategy when selecting toward which path to forward their traffic, taking into consideration operational costs as well as performance goals. We present enhanced behaviors to the decision-making core of three routing protocols, the Border Gateway Protocol (BGP), the Locator/Identifier Separation Protocol (LISP) and, at a minor extent, the Multipath TCP (MPTCP) protocol. For each protocol framework we present how routing strategies can be computed, selected and actually operated by real systems, also applying concepts from non-cooperative game theory, evaluating the impact of the routing solutions in terms of operational costs and network performance. The thesis adopts an experimental methodology willing to experiment and evaluate proposals via realistic simulations or actual implementation and observation of real systems. Most of the results are made reproducible by open sourcing the corresponding code.
