摘要：Information-centric networking (ICN) is one of the rising Internet paradigms proposed to beat the defect of the current host-centric Internet. ICN relies on the name to access contents rather than its original location, which provides substantial flexibility for users to obtain the contents. In-network caching is one of the most important features of the ICN because it has a significant role in improving network performance such as reducing server load, congestion, and delay caused by users. In-network caching is managed by a caching strategy that determines what, where and when to cache the content, to make content is available for requesters without going to servers. In recent years, caching strategies have attracted considerable interest from researchers, and they have proposed many caching strategies to manage the contents to enhance the performance of ICN. In this paper, the caching strategies and its characteristics are clearly described and discussed; furthermore, the caching strategies are categorized based on a set of common characteristics to be easy to understand.
