Cloud Computing for Global Name-Resolution in Information-centric Networks

Information-Centric Networking (ICN) is a novel paradigm for future Internet architectures. It exploits the current trend in Internet usage which mostly involves information dissemination. ICN architectures based on the publish/subscribe model use names for information in order to route requests and data, as well as to facilitate in-network caching, anycasting and multicasting for efficient content delivery. However, the numberof named information objects is expected to be huge in the future Internet, raising serious concerns with respect to a global-scale deployment of ICN. Routing and forwarding will require vast amounts of state, which pushes storage, maintenance and processing demands to the limit. In this paper we discuss the feasibility of deploying the Data Oriented Networking Architecture (DONA) by leveraging cloud computing facilities. We identify the exact scalability concerns for DONA based on simulations over a realistic model of the current Internet topology and find thatregistrations for information objects lead to a state explosion. For this reason, we then discuss how cloud facilities can assist DONA deployment, focusing on various options for deploying DONA in the cloud and their suitability for different areas of the inter-network.
