Abstract: Remote peering (RP) has crucially altered the Internet topology and its economics. Increasingly popular thanks to its lower costs and simplicity, RP has shifted the member base of Internet eXchange Points (IXPs) from strictly local to include ASes located any- where in the world. While the popularity of RP is well understood, its implications on Internet routing and performance are not. We propose as thesis a comprehensive measurement study of RP in the wild, based on a representative set of IXPs (including some of the largest ones in the world, covering the five continents). We will first identify the challenges of inferring remote peering and the limitations of the existing methodologies. Next, we will investigate RP’s impact on the control plane, including the proportion of remotely reachable prefixes/routes for IPv4 and IPv6, whether ASes prefer them over local ones (i.e., via route characteristics or traffic engineering), and their stability and availability on BGP updates. Then, we will study the impact of RP on the data plane, including the latency and variability comparison to reach remote prefixes via either RP or a Transit provider connection and the relevance of RP on the overall IXP traffic. Finally, we will study whether RP can potentially introduce undesired consequences to the interconnection, such as routing detours. To demonstrate the feasibility of the proposal, we conducted a preliminary study, tackling a subset of the questions and using a smaller set of IXPs, al- ready with some interesting findings.
