Exploiting Parallelism in Hierarchical Content Stores for High-speed ICN Routers
Résumé
Information-centric network (ICN) is a novel architecture identifying data as a first class citizen, and caching
as a prominent low-level feature. Yet, efficiently using large storage (e.g., 1 TB) at line rate (e.g., 10 Gbps)
is not trivial: in our previous work, we proposed an ICN router design equipped with hierarchical caches,
that exploits peculiarities of the ICN traffic arrival process. In this paper, we implement such proposal in
the NDN Forwarding Daemon (NFD), and carry on a thorough experimental evaluation of its performance
with an emulation methodology on common off the shelf hardware. Our study testifies the interest and
feasibility of the approach.
