<p><P>PROBLEM TO BE SOLVED: To shorten a transfer delay of multicast traffic between end nodes in overlay multicast. <P>SOLUTION: An overlay node includes a capacity managing part and a reconnection managing part. The capacity managing part calculates the capacity of a self-node, and transmits a capacity notification message showing the capacity and address of the self-node to the next hop node of a downstream side. The reconnection managing part performs reconnection instruction processing in response to the capacity notification message received from an upstream side. In the reconnection instruction processing, the reconnection managing part selects an end node within the number of permissions from local end node that is currently connected to the self-node with reference to the notified capacity. Then, the reconnection managing part instructs the selected end node so as to reconnect an upstream overlay node designated by the notified address. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
