Caching methodologies in Content centric networking (CCN): A survey.

Nowadays, Information centric networking has tremendous importance in accessing internet based applications. The increasing rate of Internet traffic has encouraged to adapt content centric architectures to better serve content provider needs and user demand of internet based applications which is based on receiver driven data retrieval. These architectures have built-in network Caches and these properties improves efficiency of content delivery with high speed and efficiency and they are very efficient in comparison with traditional caching of internet access methodologies. By using Information centric architectures, users need not download content from content server despite they can easily access data from nearby caches. User requested content is independent of the location of that data by use of caching approaches and does not rely on storage and transmission methodologies of that content. There has been many researches going to base on caching approaches in the Content centric network. Efficient caching is essential to reduce delay and to enhance performance of the network. Efficient caching is essential to reduce delay and to enhance performance of the network. So, in this paper, we presented a survey on caching approaches and related issues like cache content, availability, and cache router localization and so on. The main focus to present a state-of-art research paper for researchers who are interested in the area of Information centric network so that they can get an idea about what work and issues have been developed and arises in this particular caching field.
