OPTIMIZING SSD-BASED CONTENT CACHES IN CONTENT DELIVERY NETWORKS

摘要

A method for caching using a solid-state drive (SSD)-based cache includes: determining a set of potential objects for storage at the SSD-based cache; ranking the potential objects for storage based on expected utility values corresponding to each potential object for storage; selecting objects for storage from the potential objects for storage based on the ranking; and causing the selected objects to be written to the SSD-based cache. Further, a reserve capacity for the SSD-based cache may be dynamically adjusted based on the write speed associated with an object being written to the SSD-based cache.

1. A method for caching using a solid-state drive (SSD)-based cache, the method comprising:
determining, by a controller, a set of potential objects for storage at the SSD-based cache; ranking, by the controller, the potential objects for storage based on a respective expected utility value corresponding to each potential object for storage; selecting, by the controller, objects for storage from the potential objects for storage based on the ranking; causing, by the controller, the selected objects to be written to the SSD-based cache.
