A network system

摘要

A network system is constructed by connecting a plurality of terminals to each other so that information such as audio data can be sent and/or received through peer-to-peer communication. The network system includes a plurality of groups each constituted from a plurality of terminals that execute the peer-to-peer communication with each other. Each group includes a master terminal connected to other terminals in the group and a plurality of slave terminals each connected to the master terminal. Each of the slave terminals communicates with the master terminal and the other slave terminals in the group. The master terminal communicates with master terminals in other groups in addition to the slave terminals in the group. In the case where a slave terminal communicates with a terminal in any other group, the slave terminal communicates with the terminal via the master terminal in the group to which the slave terminal belongs.
