Cache "Less for More" in Information-Centric Networks
Ubiquitous in-network caching is one of the key aspects of Information-Centric Networking (ICN) which has recently received widespread research interest. In one of the key relevant proposals known as Networking Named Content (NNC), the premise is that leveraging in-network caching to store content in every node it traverses along the delivery path can enhance content delivery. The authors question such indiscriminate universal caching strategy and investigate whether caching less can actually achieve more. Specifically, they investigate if caching only in a subset of node(s) along the content delivery path can achieve better performance in terms of cache and server hit rates.
