ABSTRACT:
An information processing apparatus is provided capable of effectively utilizing resources in data transmission processes executed by a plurality of control units. A contents delivery apparatus includes network IFs, control units, disk drives used by the respective control units, and cache areas in which content data read by the respective control units from the respective disk drives is temporarily stored. Upon receiving a content data delivery request from a terminal device, the control unit of the contents delivery apparatus checks whether the requested data is present in the cache area, and if it is present (cache hit), replicates the data to the disk drive used by any one of other control units to notify a portal server allocating a delivery destination so that it is well prepared for a new delivery request from the terminal device.
