Named Data Networking (NDN) is an emerging technology that aims to provide rapid and efficient content distribution and retrieval in the network. This paper focuses on the impact of selecting the pair between cache replacement and placement within NDN, an aspect often overlooked in previous research. Four cache placement strategies will be implemented in the initial simulation: Leave Copy Down (LCD), Leave Copy Everywhere (LCE), Prob Cache, and Cache Less for More (CL4M). Each cache placement will be combined with two replacements: least frequently used (LFU) and least recently used (LRU). The effects of these combinations on critical metrics such as cache hit ratio, latency, link load, and path stretch are investigated. The results reveal that LCE combined with LFU demonstrates remarkable enhancements in all measurements over LCE coupled with LRU. These findings underscore the importance of meticulous selection and optimization of cache placement and replacement strategies in NDN environments to augment network efficiency and performance.
