Title
Exploit the known or explore the unknown?: hamlet-like doubts in ICN.
Abstract
Most Information Centric Networking designs propose the usage of widely distributed in-network storage. However, the huge amount of content exchanged in the Internet, and the volatility of content replicas cached across the network pose significant challenges to the definition of a scalable routing protocol able to address all available copies. In addition, the number of available copies of a given content item and their distribution among caches is clearly impacted by the request forwarding policy. In this paper we gather initial design considerations for an ICN request forwarding strategy by spanning over two extremes: a deterministic exploitation of forwarding information towards a "known" copy and a random network exploration towards an "unknown" copy, via request flooding. By means of packet-level simulations, we investigate the performance trade-offs of exploitation/exploration approaches, and introduce an hybrid solution. Our forwarding scheme shows a good potential, whether carefully tuned, in terms of delivery performance, implicit cache coordination and possible reduction of forwarding table size.
