Abstract: The Named Data Networking (NDN) is the forthcoming internet architecture which is developed and tested as an alternative to the standard IP architecture. It is acquired from Information Centric Networking (ICN). The data accessing depends on the name of the data content so that it is not depended on any particular server or location. Each router in the network stores particular data as cache based on different policies like Least Frequently Used (LFU), Universal Caching (UC), First in First out (FIFO), Least Recently Used (LRU), and etc., Caching process in NDN is the main function, where the availability of data to the user is based on getting and storing the appropriate required data in the storage area. So that it must be available whenever the user request for it. Due to this function, it is the major area to be concerned and researched in the NDN architecture. This survey is done on several caching strategies, their algorithm, caching types, their advantages and issues.Based on the survey work, various cache methods are compared depend on different criteria. Different challenges in their works are analyzed, and a proposal based on these works is given at the end of this paper.
