Network group management system

摘要

As a result of performing a comparing and determining process of determining the relationship among the bandwidth of distributed data in real time in a local group, the incoming data bandwidth to the local group, and the outgoing data bandwidth from the local group, the increase/decrease management and the connection management of each terminal device in the local group are performed. The comparing and determining process compares, for example, a sum of the total sum of the terminal possessed transfer bandwidths and the incoming data bandwidth from other groups to the local group with a sum of the value obtained by multiplying the bandwidth of distributed data in the local group by the number of terminal devices in the local group, the outgoing data bandwidth from the local group, and a predetermined determination margin.

1. A network group management system in a streaming distribution system for grouping terminal devices and transferring data in real time among the terminal devices, the network group management system including a group management terminal device for grouping and managing terminal devices, the group management terminal device comprising:
a processor that performs a process including
a communication control process that collects terminal information including a data transfer bandwidth relating to each terminal device in a local group from each terminal device;a terminal information management process that holds the collected terminal information;a group band management process that holds total sum of data transmission bandwidth held by each terminal device in the local group according to the collected terminal information; anda control process that performs management of an entry of a new terminal device into the local group and that performs connection management of each terminal device in the local group by using a relationship among bandwidths of distributed data in real time in the local group, an incoming data bandwidth to the local group, and an outgoing data bandwidth from the local group according to the terminal information held by the terminal information management device and total sum of the data transmission bandwidths held by the group band management device, wherein the relationship is a magnitude relation between a value which is added a total sum of transfer bandwidths of terminals to the incoming data bandwidth from another group to the local group and a value which is a sum of a value obtained by multiplying the bandwidth of distributed data in the local group by a number of the terminal devices in the local group, the outgoing data bandwidth from the local group, and a predetermined determination margin.
