INFORM: a Dynamic Interest Forwarding Mechanism for Information Centric Networking

Abstract : Information Centric Networking is a new communication paradigm where network primitives are based on named-data rather than host identifiers. In ICN, data retrieval is triggered by user requests which are forwarded towards a copy of the desired content item. Data can be retrieved either from a server that permanently provides a content item, or from a temporary item copy opportunistically cached by an in-network node. As the availability of cached items dynamically varies over time, the request forwarding scheme should be adapted accordingly. In this paper we focus on dynamic request forwarding in ICN, and develop an approach, inspired by Q-routing framework, that we show to outperform algorithms currently available in the state of the art.
