Title
(EN) Hierarchical cost based caching for online media
Abstract
(EN)

A method of operating a first cache device may include receiving, at the first cache device, a request to send a first asset to a second device; determining whether the first asset is stored at the first cache device; and when the determining determines that the first asset is not stored at the first cache device, obtaining, at the first cache device, the first asset, comparing, at the first cache device, a moving average of a marginal value of the first asset with respect to the first cache device and a characteristic marginal value of the first cache device, calculating a cost associated with the first asset, selectively storing the first asset at the first cache device based on the comparison, and sending the obtained first asset and the calculated cost to the second device.
