Compare that with the reactive mode of regular life.

When this doesn't happen, then a leader will simply work in reactive mode all the time-and will lose any ability to prioritize.

During trauma the reptilian brain (the brain stem) responsible for the survival response and autonomic body processes takes over and the body goes into reactive mode.

In reactive mode the controller acts after these requests and creates and installs a rule in the flow table for the corresponding packet if necessary.
