The presence of content stores in routers enables in-network caching in Named Data Networks (NDN) to improve customer experience, especially when content distribution is considered. Typically, homogeneous caching is assumed in the network where each router operates its cache according to the installed policy. Numerous in-network caching policies that vary in admission logic and caching attributes have been urged. Hence, the policies vary in performance (efficiency) according to unbounded network factors such as caching capacity, users’ request pattern, content popularity distribution, and application type (amongst other contexts). A single scheme may not effectively realize all the network characteristics and vandalize the efficient use of precious cache spaces. Therefore, a new strategy capable of dynamically selecting the optimal caching policy under varying network contexts is inevitable. In this …
