摘要： A receiving terminal is provided that prevents a load on a network near a receiving terminal from increasing when a retransmission request is made to a plurality of other terminals, and enables the probability of being able to compensate for a lost packet by means of a retransmission packet to be increased. In a receiving terminal that transmits a retransmission request for compensating for a lost packet lost in a network, a measurement section measures a time period corresponding to a distance in the network between the receiving terminal and a plurality of receiving terminals, a calculation section calculates for each of the receiving terminals a float (spare time period) found by subtracting the current time and a time period measured by the measurement section from a playback time at which a retransmitted packet is played back, and a decision section decides retransmission request transmission timing and a retransmission request transmission destination for each of the receiving terminals based on the calculated floats.

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.

摘要： It is an object to provide a flow control method in which a packet round trip time is not excessively calculated out and its performance is not unnecessarily deteriorated even at the time of continuously connected packet transfers through relays of a plurality of receiving terminal devices. This method is directed to a flow control method in which the delivery of packets are carried out through relays of a plurality of receiving terminal devices. The method is comprised of steps (S501-S517) for acquiring a packet round trip time for every pair of neighboring terminal devices in a path of the delivery, a selection step for selecting one from the acquired round trip time in accordance with a predetermined standard, and a step (S518) for calculating a packet transmission rate on the basis of the selected round trip time, so that the round trip time of each receiving terminal device is measured and the transmission rate is calculated in accordance with the measured result. Thus, a packet round trip time is not excessively calculated out, and data transmission performance can be improved.

摘要： A terminal apparatus is provided that minimizes traffic congestion by reducing end-to-end delay and maximizes the bandwidth available in shared N-tree ALM nodes. In this terminal apparatus, an optimal stream path information table (204) stores N-tree session information for all nodes. A server forwarding table (202) stores bandwidth-fair ALM route information for all nodes in a specific N-tree session. An ALM forwarding table constructor (218) updates M-tree session information stored in an optimal stream path information table (204) using network metrics and heuristic rules stored in a heuristic rule database (206), executes ALM_N-tree algorithm using updated N-tree session information, and thereby generates bandwidth-fair ALM route information.
