A survey on named data networking

Named Data Networking (NDN) is an entirely new internet architecture inspired by years of empirical research into network usage. NDN is related to Content Centric Networking. Unique feature of NDN is its adaptive forwarding plane. In NDN, the packets carry the data name instead of the source and destination address. In NDN, communication takes place by the exchange of Interest and Data packets. Data consumers send Interest packets in the form of names. Routers forward the Interest packet based on the data name and also maintain the state information of pending Interests that enable NDN routers to detect loops, measure performance of different path, quickly detect failures and retry alternative path. The producer replies with data packet that takes the reverse path of Interests. In this paper the motivation and the vision of NDN architecture, and basic components and operations of NDN are described. Also the strength and weakness of NDN are reviewed. The final discussion aims to identify challenges and some future directions for NDN deployment.
