<p>A content delivery system wherein an occurrence of a traffic, the value of which is below a predetermined threshold value, can cause stream data to permeate all of the nodes in a community in a given time. In this system, a communication terminal apparatus (300) uses a control part (304) to determine, based on information (a TTL part, a relay part and a content part) established in a content delivery message, a coincidence between user attribute information established in the content part and user attribute information stored in a storage part (302), thereby deciding whether to execute a content reproduction. Furthermore, in a process of controlling a relay transmission, the control part (304) controls, based on the information of the TTL and relay parts established in the content delivery message, the state of the relay transmission to other nodes based on link information stored in the storage part (302).</p> |
