Network system, node device, data distribution method, information recording medium, and program

Abstract

A distribution request transmission unit (301) transmits a distribution request to a server. When a terminal (12) is selected as the most significant node by a server, a path decision unit (302) decides distribution paths arranged in the order from the more significant to the less significant node from the terminal (12) for each of the nodes introduced by the server. A data reception unit (303) receives data distributed from anode immediately above which is connected according to the decided distribution path. When there is a node immediately below which is connected according to the distribution path, a data transmission unit (308) transmits the received data to the node immediately below. When the data reception unit (303) receives data, a reception report return unit (309) returns a reception report to the most significant node if the reception report return unit (309) is the least significant node.

Description

technical field [0001] The present invention relates to a network system, a node device, a data distribution method, an information recording medium, and a program capable of appropriately reducing the load at the time of data distribution. Background technique [0002] Conventionally, people have provided various data using networks such as the Internet. As an example, a game company or the like distributes data such as an evaluation version program (a promotional program whose game range is partially limited) in order to allow users to experience a game before release or the like. In addition, it also distributes data such as game correction programs and libraries. [0003] Specifically, evaluation version programs and the like to be distributed are stored on the server of the game company, and users can freely download them using a game machine or the like. [0004] In addition, in this technical field, there is also disclosed a technique in which a correction program, ...

AI Technical Summary

Problems solved by technology

[0009] However, in the case of distributing a game (evaluation program) with high user interest, it is likely that more users will download it at the same time.

In this case, the actual situation is that even if the existing load distribution technology is adopted, the load will increase and exceed the allowable range, and effective distribution cannot be carried out
