Pricing in Information-Centric Network Interconnection
The authors propose a pricing model to study the economic incentives for caching and sharing content in the interconnection of Information-Centric Networks (ICNs). While collaborative caching in ICNs is a key feature to success in improving network performance and reducing delivery costs in content distribution, the current pricing strategies in the Internet are not incentive-compatible with ICN interconnection. In this paper, they clarify the issue by considering the existing value and money flows in today's Content Delivery Networks (CDNs) and studying their possible evolution in a future ICN interconnection scenario. They model and analyze the interactions in price and caching investments among transit ISPs, access ISPs and content providers in ICN interconnection.
