摘要

Even if there is a difference in the easiness of delivering a content among content holders (CH), a delivery system enables a requestor (RQ) to rapidly and efficiently receive a desired content. A route node (RN) or a cash node (CN) includes easiness information (HP) representing the easiness of content delivery from a content holder (CH) in index information (EXX) recorded referenceably by a requestor (RQ) in addition to a content ID and the IP address of a content holder. A requestor (RQ) references the easiness information (HP) to determine a content holder (CH) to deliver the desired content, preferentially selects the content holder (CH) having a higher easiness of content delivery, and receives the content delivered.
