According to one embodiment, a request for data is received by a network device. A cache management system running on the network device estimates, for each of multiple cache entries of a cache managed by the cache management system, a computational cost of reproducing data cached within each of the cache entries by respective origin storage devices from which the respective cached data originated. The cache management system estimates a communication latency between the cache and the respective origin storage devices. The cache management system enables the cache to replace data cached within a selected cache entry with the requested data based on the estimated computational costs and the estimated communication latencies."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cache management based on factors relating to replacement cost of data","description":"Systems and methods for a cache replacement policy that takes into consideration factors relating to the replacement cost of currently cached data and/or the replacement cost of requested data.
