Summary Astabilizing system is one which if started at any state is guaranteed to reach a state after which the system cannot deviate from its intended specification. In this paper, we propose a new variation of this notion, called pseudo-stabilization. Apseudo-stabilizing system is one which if started at any state is guaranteed to reach a state after which the system does not deriate from its intended specification. Thus, the difference between the two notions comes down to the difference between “cannot” and “does not” — a difference that hardly matters in many practical situations. As it happens, a number of well-known systems, for example the alternating-bit protocol, are pseudo-stabilizing but not stabilizing. We conclude that one should not try to make any such system stabilizing, especially if stabilization comes at a high price.
