CCN forwarding engine based on Bloom filters

Abstract

The lack of scalable routing algorithms is one of the main obstacles that slow down a large deployment of Content Centric Networking on an Internet-scale. From one side, content based networking promises to solve the current problems of the Internet. On the other hand, instead, it requires routers to account for a very huge amount of content names. Bloom Filters are widely recognized as a possible solution to this limitation. At the same time, their adoption requires careful tuning rules and novel design methodologies. In this perspective, the present contribution proposes a Bloom Filter-based routing scheme for Content Centric Networking (CCN) and shows several preliminary observations about Bloom Filters size and signaling overhead.
