How to automatically alter rtmp /rtmfp connections

Question

Hi ,there!   I'm developing  a real-time game project . First , i wanna  use rmtfp  to do the video/audio communication so that i can save a lot bandwidth . when  A scrible B  and publish Astream, and B scrible A and publish Bstream.  how do i know if they(A and B) are connected,then give them both a hint ? if connected .,then how do i know the delay status between them ? if the delay latency is more than 5 seconds, then i 'll think about using rtmp to connect. Any one can help ?

private function netConnectionHandler(event:NetStatusEvent):void
    status("NetConnection event: " + event.info.code + "\n");
             switch (event.info.code)
                 case "NetConnection.Connect.Success":
                  connectSuccess();
                     break;
                    case "NetConnection.Connect.Closed":
                     currentState = LoginNotConnected;
                     break;
                    case "NetStream.Connect.Success":
                     // we get this when other party connects to our outgoing stream
                     status("Connection from: " + event.info.stream.farID + "\n");
                     break;
                    case "NetConnection.Connect.Failed":
                     status("Unable to connect to " + connectUrl + "\n");
                   // swift the rtmp mode
                   changeRTMP();
                     currentState = LoginNotConnected;
                     break;
private function connectSuccess():void
    status("Connected, my ID: " + netConnection.nearID + "\n");
                // exchange peer id using web service
    idManager = new HttpIdManager();
    idManager.service = WebServiceUrl;
               idManager.addEventListener("registerSuccess", idManagerEvent);
               idManager.addEventListener("registerFailure", idManagerEvent);
               idManager.addEventListener("lookupFailure", idManagerEvent);
               idManager.addEventListener("lookupSuccess", idManagerEvent);
               idManager.addEventListener("idManagerError", idManagerEvent);
               idManager.register(userNameInput.text, netConnection.nearID);
private function changeRTMP(){
when the case    NetConnection.Connect.Failed    i could change to rtmp mode ,but if  NetConnection.Connect.Success .  how do i know the delay seconds between A and B . then i can find the optimun way (rtmp/rtmfp
