These data packets are not continuous. However when I unplug it from the network there isn’t any notification that the server is now unavailable.

I’m not quite sure what you’re asking, but - if you wish - you could modify your “testRTSPClient” application to periodically send an “OPTIONS” command to the server.  Look at how “openRTSP” implements the ‘-K’ option; specifically, note the “checkSessionTimeoutBrokenServer()” function in “playCommon.cpp”.
