B4J Question Exchange data between PCs

Good morning, I have to create an app made B4J that runs on three or more PCs and via LAN network allows the three programs to exchange data strings. ("AZX32DD11" eg. String).

There one of the three PCs is that the supervisor when necessary consults the other two programs to receive or send data strings.

What to use? ... I had thought AsyncStream
Any suggestions or example to study?

Thanks Marco
