Abstract
Information-Centric Networking (ICN) is proposed to address the inefficiency of content delivery of IP networks from the perspective of architecture. In contrast, Content Delivery Network (CDN) is an overlay solution in current IP networks. We believe that even though ICN is fully deployed, there is still a role for CDNs to play in ICN networks. Since ISPs in ICN will replicate and forward contents according to their policies and interests, it may not align with the objectives of Content Providers (CPs). Therefore, CPs are willing pay a third party (i.e., CDN providers) a certain fee to meet their own requirements. In this paper, we propose to use the inventory model of Supply Chain Management (SCM) in logistics to formulate the content delivery process of ICN networks. The product-centric model of SCM is well-suited for the content-centric content delivery process of ICN networks. Also, we propose the system framework of inventory Centric Delivery Network (iCDN). Simulation results show that the average cost and link usage of the SCM-based algorithm can be reduced by 52% and 15% respectively compared to the baseline approach.
