While comparing with traditional Internet to improve the content (information) on the Web, Information Centric Network (ICN) with names gained much interest among various researchers. The major aim of ICN is to reduce the frequent access or redundancy to the host (i.e. information provider), which paved a new way to introduce some popular architecture of ICN. Caching is one of the major variables to solve the frequency and recency problem, when compared with other efforts and issues in routing, power consumption, and security and naming. Therefore, this survey work discussed some of the approaches developed in ICN architecture for investigating the caching to reduce the total consumption of bandwidth, the stream of upwards and downwards, and also enhanced the Delivery of Service (DoS).This surveys gives some suggestions for improving the caching performance in ICN and also pointed out some of major issues that impact the deployment of caches via frequency, retrieval cost, regency, updation in replacements and caches, content size and coordination. In addition, to identify the key weakness and main unresolved research challenges, several cache characteristics were presented in this review.
