Abstract

Scoped-flooding is a technique for content discovery in a broad networking context. This paper investigates the effects of scoped-flooding on various topologies in informationcentric networking. Using the proposed ring model, we show that flooding can be constrained within a very small neighbourhood to achieve most of the gains which come from areas where the growth rate is relatively low, i.e., the network edge. We also study two flooding strategies and compare their behaviours. Given that caching schemes favour more popular items in competition for cache space, popular items are expected to be stored in diverse parts of the network compared to the less popular items. We propose to exploit the resulting divergence in availability along with the routers' topological properties to fine tune the flooding radius. Our results shed light on designing efficient content discovery mechanism for future information-centric networks.
