<p><P>PROBLEM TO BE SOLVED: To provide a multicast system, a multicast tree construction method, and a program that can quickly and flexibly control variations in delivery delay. <P>SOLUTION: The multicast system includes means for setting a delivery delay, and means for constructing a multicast tree so as to maximize the number of nodes where delay control for reducing a delay variation from the delivery delay set by the setting means is unnecessary. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
