Abstract (in Japanese) (See Japanese page) 
(in English) Caching is empirically proven to enhance network connectivity, particularly for popular content. The cache replacement algorithm is crucial in hit ratio performance within caching systems. Delayed-hit caching, introduced by some authors, significantly degrades caching performance. To address this, we propose the BSA (Burst Score Aggregation) cache replacement algorithm, which effectively mitigates hit ratio decline due to delayed-hit caching, as empirically validated. Then, we enhance our algorithm to R-BSA (Reduced BSA), which manages to reduce the processing load. This paper focuses on investigating the intervals at which the BSA (Burst Score Aggregation) database level is reset. The research findings a pivotal role played by the reset interval in influencing the behavior of the R-BSA algorithm concerning variations in content skewness parameters. Specifically, when the BSA database level is reset at shorter intervals, the R-BSA algorithm tends to display greater sensitivity to lower content skewness parameters. Conversely, opting for a longer reset interval for the BSA database level results in an increased sensitivity to higher content skewness parameters. Consequently, the choice of reset interval for the BSA database level substantially impacts the algorithm's adaptability to shifts in the popularity of requested content trends.
