Reliable Content Distribution using ICN


Information Centric Networking [ADI12] has an intrinsic distributed nature, which eases decentralizing formerly centralized protocols. Nevertheless, implementing fully distributed protocols on a large scale remains challenging due to the concurrent nature of network elements.

Cache inconsistency becomes a problem whenever different content, or multiple versions of the same content, can answer the same query, in the first part of this book we focus on the detrimental impact that this has on Privacy and Communication Many-To-Many.

With regard to privacy we show that hierarchical caching introduces a considerable la- tency in updating Access Control Lists. We study the problem analytically and via simula- tion and propose two possible solutions: one for the generic problem of privacy in ICN and one for the specific case of Social Networking.

In the latter case of many-to-many communication, we prove that the current state of the art limits the throughput and frequently suffers data loss.

The second and last part of the book switches topic to the impact of ICN on wireless ad-hoc networks. On this matter, our work consists of an original algorithm for message dissemination; and implementing seamless path redundancy and multi-source download.
