In IP, the data are transferred amid the source and destination using the IP address. But in NDN instead of using the IP address, the name prefix is used to access the data directly from the source. In general, NDN comprises of three vital components which are the content store (CS), pending interest table (PIT) and forwarding information base (FIB). The content store and pending interest table would compare, analyze and match the content name prefix exactly however forwarding interest base matches the longest prefix. The PIT possesses two issues which are the high memory usage and the name lookup. This survey has covered several papers related to PIT memory and lookup. The paper has been concluded by identifying the problems and challenges in the PIT.
