increasing bandwidth while publishing live video

Hi all,

     I have made a sample application for publishing video through FMS using as3.

     In that I had used the same code as given in the sample provided by the adobe,

     m_nc = new NetConnection("rtmpt://localhost:1935/Test");

     private function onNetStatus(event:NetStatusEvent):void
  {

     switch (event.info.code)
   {
    case "NetConnection.Connect.Success" :
     m_ns = new NetStream(m_nc);    
     m_nsPlayer = new NetStream(m_nc);
     m_nc.call("checkBandwidth", null);
       var camName:String = setCamera();
      if(camName == "null")
      {
         trace("Sorry! No Camera found");
         break;
       }
            if(camName == "NoWebCam")
            {
                 if(ExternalInterface.available)
                 {
                  ExternalInterface.call("CameraNotFound");
                 }
                 break;
             }
           var micIndex:int = setMicrophone();
           if(micIndex == -1)
           {
            trace("Sorry! No Mic found");
            break;
           }   
           publishCamera(camName,micIndex);
           displayPublishingVideo();
          }       
          break;

     }

}

private function publishCamera(camName:String,micIndex:int):void
  {
   m_cam=Camera.getCamera(camName);
   switch(m_resolution)
   {
    case "160x120" : m_cam.setMode(160,120,15);
     break;
    case "320x240" : m_cam.setMode(320,240,15);
     break;
    case "640x480" : m_cam.setMode(640,480,15);
     break;
    default      : m_cam.setMode(320,240,15);
     break;
   }
   m_cam.setQuality(0,85);
   if(micIndex != -1)
   {
    m_mic=Microphone.getMicrophone();
    m_mic.codec = SoundCodec.SPEEX;
    m_mic.setUseEchoSuppression(true);   
    m_mic.setLoopBack(false);
    m_mic.setSilenceLevel(20);
    m_ns.attachAudio(m_mic);   
   }  
   m_ns.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
   m_ns.addEventListener(AsyncErrorEvent.ASYNC_ERROR, onAsyncError);
   m_ns.attachCamera(m_cam);
   m_ns.publish(m_publishName, "live");
   stage.addEventListener(MouseEvent.CLICK, onStageClick);
  }

The above was the sample code just for publishing the video.

The similar code for viewing the published video was written

private function displayPlaybackVideo(publishName:String,muteSound:String):void
  {

     m_nsPlayer.bufferTime = 0.6;
   m_nsPlayer.addEventListener(NetStatusEvent.NET_STATUS,onstatus);
   m_vidPlayer.height = 480;
   m_vidPlayer.attachNetStream(m_nsPlayer);
   addChild(m_vidPlayer);
   m_isVideoChildAdded = true;

}

now after writing code I launched the application and started analyising the server console.

The server console shows the regular increament in bandwidth which hampers my video publish after 8-10 minutes resulting in stuck of video.

So, please help me in resolving the problem.

Thanx in advance.
