A Cache Replacement Strategy Based on Hierarchical Popularity in NDN
YingQi Li, Meiju Yu, Ru Li · 2018
NDN (Named Data Networking, NDN) which is one of the next generation network architectures based on named-data, uses in-network caching. Cache has limited capacity, so the cache replacement policy determines which content is evicted when the cache space is full. This paper analyzes some cache replacement strategies in NDN, and puts forword a cache replacement strategy based on hierarchical popularity, then compares the effect of different cache replacement strategies to the cache performance through simulation experiments. Cache performance is evaluated in provision of cache hit ratio.
