A first node device transmits to a second node device unique identification information corresponding to specific common information, receives from the information saving node device the relevant information regarding the information saving node device, and requests to a selected information saving node device delivery of the specific common information,

Information delivery system, delivery request program, transfer program, delivery program, and the like

The present invention provides a distribution system in which even in the case where the content distributability varies among content holders, desired content can be promptly and efficiently received by a requester. To index information recorded in a root node or cache node so that it can be referred to from the requester, in addition to content ID and IP address of a content holder, easiness information indicative of easiness of distribution of content from the content holder are added. When the requester determines a content holder as a distribution source, a content holder having high distributability is preferentially selected with reference to the easiness information and content is distributed from the selected content holder.

Information processing apparatus and storing apparatus, information processing method and storing method, and recording medium that promptly and efficiently distributes content

In a first node in a system having nodes connected to each other as a network, request information including identification information and request number of location information indicating a location in the network of information saving nodes is transmitted to a second node. In the second node, the location information and identification information are saved. At least the location information whose number corresponds to the request number is transmitted to the first node when the number of the saved location information meets the request number. Otherwise, the location information whose number corresponds to the number of the saved location information is transmitted to the first node. The received request information is transferred when the second node itself is not a management node, to a node interposed between the second node and the management node, or to the management node when there is no node therebetween.
