摘要： After a delivery tree is reorganized by a local processing, all terminal devices can recognize, in a short time, a delivery route as changed. In a local one of the terminal devices, if the local terminal device is a source node and further if the load of the CPU in any one of nodes exceeds a threshold value or the available band of the circuit line between nodes exceeds a threshold value, then a delivery tree organizing unit (462) determines nodes that receive a packet via such nodes and reselects a delivery route of the determined nodes. A packet structure modifying unit (464), if the local terminal device is the source node, modifies the header of a packet in accordance with delivery route information stored in a delivery route database (412). The packet structure modifying unit (464) then instructs, in accordance with the description of the header, a packet replicating unit (426) on a number of packet replicas and on the transmission destination of the packets.

A first branch allocating unit allocates at least a part of the upload link bandwidth which is assigned to each of the terminals that has the lower terminal allocated, so that the part of upload link bandwidth acts as a logical first branch for distributing the data stream; and a second branch allocating unit allocates a remaining bandwidth, unused as the logical first branch, to a terminal provided in a hierarchy level below the terminal having the remaining bandwidth, so that the remaining bandwidth acts as a logical second branch for distributing reference data regarding the data stream.

摘要： A generating unit (210) generates group formation data for forming groups among nodes making up an ALM distribution tree. A transmitting unit (220) transmits the group formation data to a node that is a destination set to a communication terminal. When a condition for grouping is satisfied, the generating unit (210) converts the group formation data into data for changing at least one of the number of groups and the number of nodes corresponding to each of the groups. Every time the group formation data is converted, the transmitting unit (220) transmits the converted group formation data to the node that is the destination set to the communication terminal. The group formation data is data for forming a group in which a local improvement process of switching positions of two nodes with each other is performed.
