    re-enabling the data flow to the port from the other ports of the plurality of ports when the port satisfies a predetermined spatial requirement and a predetermined temporal requirement;

    wherein the predefined temporal requirement is met when a timer, set during the disabling step, has exceeded a predetermined amount of time.
