Abstract

This invention is to autonomously control reduction of wide-area traffic by sharing the same stream among nodes while avoiding distribution route localization due to route selection at the network level, and efficiently distribute a real-time data stream maintaining a high quality. In a real-time data distribution control system for distributing real-time data such as image or audio data using a network, node devices having data transmission/reception/relay means are put into groups. When the real-time data distribution route is to be selected among the node groups, an upper node group is selected in units of transmission sources.
