<p>PROBLEM TO BE SOLVED: To optimize communication using a scalable peer group.SOLUTION: Some peers are shown where a peer message is transmitted and received before so as to relate to one or a plurality of distribution restrictions of the peer message, and a center tracking object is stored in at least a part of a common section specified so that at least a part of the center tracking object can share with other peers propagation of transmission and reception of a message annotation with the other peers. Access is gained by transmitting and receiving an annotation associated with a peer message from the center tracking object, the one or the plurality of distribution restrictions with respect to the peer message are evaluated based on the transmission and reception of the annotation with respect to the accessed peer message, and it is determined based upon the evaluation what peer message should be further distributed so as to maintain the distribution intention of a transmission-source peer with respect to the message.</p> |
