   Neither does the TCP re-establish connection from the client to the   
   server if the server is rebooted, powered up, hardware replaced,   
   switch to a redundant unit (and if symbolic addressing is used, change   
   of IP address).   
      
   You still need to build an additional layer to handle these events and   
   re-establishing connections for non-attended 24/7 operation.
