Abstract: The invention prevents server overload and possible server crippling due to a flooding of connect requests caused by intentional attack or otherwise. In response to a connection request from a host for a specified port, the number of connections to the port that are assigned to the host are determined. If this number exceeds a first threshold, the request is denied. It is possible to override this denial if a quality of service parameter pertaining to the host permits such an override. However, if the number of available connections to the port is less than a second threshold, the connection request is denied in any event.
