Cache management based on factors relating to replacement cost of data

Fortinet, Inc., Sunnyvale, CA, has been assigned a patent (10,148,785) developed by Katsev, Sergey, Pleasant Valley, NY, for a “cache management based on factors relating to replacement cost of data.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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 received data. According to one embodiment, data is received by a network device responsive to a request issued on behalf of a client 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 received data based on the estimated computational costs and the estimated communication latencies.

The patent application was filed on November 13, 2017 (15/811,597).
