I think you can use a short time connection many times. For example a client connects to the host and asks the host to do something and then tells the host to shutdown the connection. The host switches to the waiting mode to ready a new connection. See the diagram below.

You should have the connection timer to shutdown opened connection when the client don't send the close connection or answer event to the host for a particular time.
