A survey of information-centric networking

TLDR

ICN is a future‑Internet research paradigm that relies on in‑network caching, multiparty replication, and decoupled sender‑receiver interaction, and is being explored by many projects. The study aims to compare and discuss ICN architecture design choices to deliver a network service better suited to content distribution, mobility, and resilience to disruptions. The authors compare and discuss ICN architecture design choices—named data objects, naming and security, API, routing, transport, and caching—and outline the general advantages of ICN.

Abstract

The information-centric networking (ICN) concept is a significant common approach of several future Internet research activities. The approach leverages in-network caching, multiparty communication through replication, and interaction models decoupling senders and receivers. The goal is to provide a network infrastructure service that is better suited to today¿s use (in particular. content distribution and mobility) and more resilient to disruptions and failures. The ICN approach is being explored by a number of research projects. We compare and discuss design choices and features of proposed ICN architectures, focusing on the following main components: named data objects, naming and security, API, routing and transport, and caching. We also discuss the advantages of the ICN approach in general.
