Provided is a network node which is capable of achieving both of not excessively increasing the communication load in a network, and avoiding, as much as possible, failure of delivering data to an objective node, which is the distribution destination. The network node includes nonstructural distribution means for distributing data according to a nonstructural distribution in a network in which the nonstructural distribution can be performed, structure-type distribution means for distributing data according to a structure-type distribution using a link for the structure-type distribution established in the network, and selection means for selecting the structure-type distribution means or the nonstructural distribution means as broadcast distribution means by using a predetermined evaluation method, wherein the structure-type distribution means or the nonstructural distribution means selected as the broadcast distribution means by the selection means is used to distribute data in the network. |
