The Named Data Network (NDN) is evolving as a new Internet architecture, which would become an alternative to the traditional IP bases Internet. It has developed from researches of years into Information-Centric Networking (ICN). The communication in NDN depends on Names irrespective of IP Address or Server. Communication in NDN takes place through the interchange of Interest and Data Packets in place of server and destination addresses. The users send Interest packets to the network as names. Routers forward the packets according to the data names they carry. The data producer responds to the query by the name the Interest packet bears and sends Data packet in the reverse direction, the Interest packet came. The adaptive forwarding plane is the exclusive feature of NDN. This paper discusses different caching policies used in NDN. The basic components of NDN are taken into account. The role of Routers and how Caching helps data management in NDN architecture are also discussed.
