Abstract

The proliferation of network traffic has made inter-provider collaboration or peering a critical component of the wireline Internet architecture. By facilitating direct traffic exchange at predefined locations, it offers providers greater control over routes their data takes in the peering partner’s network, improving end-to-end latency, enabling superior congestion control, and ultimately increasing overall network throughput. However, despite these inherent advantages, it has received little attention in the cellular domain, where peering can be adopted with minor changes to core functionalities. Furthermore, as emerging Low Earth Orbit (LEO) satellite networks continue to become an integral part of the Internet ecosystem, peering is poised to play a crucial role in their global adoption, owing to their enormous cost of implementation. The goal of this dissertation is to explore the intricacies of peering in all three domains with the common objective of improving networking performance and reducing associated costs. We start with the wireline Internet, where identifying appropriate peering partners and optimal peering locationsis a critical challenge. To address this problem, we propose a machine learning-based framework that focuses on the geographic overlap of provider networks to find preferred peering partners and locations. We then extend the notion of peering to wireless networks, enabling settlement-free spectrum sharing among cellular providers. We formulate an analytical model to evaluate the effectiveness of wireless peering over traditional roaming, from both the customers’ and providers’ standpoint. Next, we move to LEO satellite networks, where it remains unclear whether it is better to peer using terrestrial or spacebased gateways. We address this by developing an economic model that quantifies the combined cost of propagating traffic through the constellation and gateway access. Finally, we investigate how traffic can be routed in the space-based approach, where data is exclusively carried using optical Inter-Satellite Links, while accounting for orbital dynamics.
