Autonomous systems are likely to play a similar role in a content-centric Internet as they do today. Thus, the content-centric Internet will be a network of cache networks, each of them optimized for local performance. In this paper we consider ASs that maintain peering agreements with each other for mutual benefit, and engage in content-level peering in order to leverage each others' cache contents. We propose a game theoretical model of the interaction and the coordination between the caches managed by peering ASs. We address the questions of whether stable and efficient content-level peering can be implemented without explicit coordination between the neighboring ASs or alternatively, whether the interaction needs to rely on explicit announcements of content reachability in order for the system to be stable. We show that without coordination content-peering can lead to stable but inefficient cache configurations. For the case of coordination we show that in order to efficiently reach a stable cache configuration, the ASs need to follow an ex-ante irrational algorithm, which is, however, ex-post rational. We validate our analytical results using simulations on the measured peering topology of more than 600 ASs.
