For several years, the number of physical devices connected to the Internet has steadily grown. Consequently, the produced and exchanged amount of data has increased, leading the current standard of the Internet to its limits. Therefore, a new approach said to solve this problem, has been introduced. Information-centric Networking (ICN) is an approach focused on evolving the Internet infrastructure away from a host-centric paradigm to a network architecture with the core principle of uniquely named data. By retrieving content using names, it is possible to identify named information independent from its location, application, storage and means of transportation. This way, the ICN approach aims to overcome the limitations of the current Internet standard, which, on the contrary, uses the location of the data to receive the content requested. This paper provides a general overview of ICN, its core principles, the most commonly proposed architecture concepts, the advantages and disadvantages of this new and revolutionary approach as well as current research challenges and opportunities.
