Abstract

This paper bridges Information-Centric Networking (ICN), a novel form of networking centered around information or content, and Redundancy Elimination (RE), a popular technique widely used to identify content with similar bytestream. The result is ICN-RE, the first ICN design that supports redundancy elimination. We show by means of numerical evaluations that ICN-RE improves bandwidth efficiency by 15-40% compared to vanilla ICN, and that the state of the art hardware can support ICN-RE at line speeds up to 100Gbps. Also, we discuss several benefits of adopting ICN-RE as a networkwide RE solution when compared to state of the art redundancy elimination designs.
