Abstract
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.
