Abstract
Internet is now being used as content distribution network also. Internet users are interested in specific contents rather than host machines where the content is located. Named Data Networking (NDN) is a step towards future Internet architecture that would be based on named data rather than numerically identified hosts. Many projects are in progress to architect the structure of the future Internet. It is envisaged that NDN would provide functional efficiency with named content applied as the core concept. NDN offers lot of research opportunities to contribute for design of future Internet architecture. In this paper we analyze the modern Internet Protocol (IP) based host- centric architecture and explore the newer scalable and more efficient architecture, based on content-centric approach. Open research issues in various area of NDN are also addressed in the paper.
