Hello Michal, Thank you for your question regarding DataSocket. It sounds like you would like to synchronize three classrooms using LabVIEW. DataSockets seem like the obvious tool for this project. This allows you to efficiently pass data over the Internet, and respond to multiple users without the complexity of low-level TCP programming. Each DataSocket connection corresponds to a specific piece of data that you want to send and can be named so that you can refer to it. The connection to the URL node can be a computer name on the same network as well as an IP address so you don't have to worry about DHCP. There are some great examples in LV7 for data sockets. Go to Help>>Find Examples Then Browse by task. Select Networking>>DataSocket>>General and here you can find many examples that use DataSocket to communicate between computers. DS Read.vi and DS Write.vi are some simple ones to get you started. One thing to remember is that the DataSocket server must be running on the =93server classroom=94 computer. All this assumes that you have LabVIEW running on all three computers. There are alternative ways to approach this problem but if you have LabVIEW on all the computers this may be the best way to implement your idea.
