Abstract
Efficient pre-reading is performed in data transmission and reception between an Edge node and a Core node. An information processing device includes a storage device, outputs client request data based on a request of a client, and stores predetermined pre-read data in the storage device before the request of the client. The device includes: a relevance calculation module configured to calculate relevance between data based on an access history of the data; and a pre-reading and deletion module configured to determine data to be deleted from the storage device using the relevance when data having predetermined relevance with the client request data is to be stored to the storage device as the pre-read data and a storage capacity of the storage device is insufficient if at least one of the client request data and the pre-read data is to be stored to the storage device.
