Abstract(in English) Caching has been proven to increase network connectivity against popular content. Caching strategy, notably the cache replacement algorithm, contributes substantially to hit ratio performance at the caching system. Several authors have introduced delayed-hit caching that causes a severe hit-ratio decline in the caching performance. We proposed a burst score aggregation (BSA) cache replacement algorithm to cope with the performance degradation because of delayed-hit caching. BSA has been proven effective against the hit ratio degradation, especially when request contents follow Zipf distribution at skewness parameter greater than 0.9. Unfortunately, BSA requires more intensive processing resources than conventional cache replacement algorithms. Therefore, we introduce reduced burst score aggregation (R-BSA) cache replacement algorithm that promotes processing load reduction compared to BSA. R-BSA shows a faster processing time of about 5% as opposed to BSA in a computer simulation. As a trade-off, the hit ratio of RBA also experiences a slight downturn of about 1% from BSA. To explain this behavior, we investigate and analyze the R-BSA cache replacement algorithm's performance and its hit ratio drops.
