At instant t, two or more sites could perceive different values for the same distributed object X. However, depending on the consistency protocol used, it might be expected that, after a while, every site in the system should see the same value for this object. In this paper, we present a formalization of the concept of convergence and analyze its relationships with several consistency models. Among other things, we claim that, by itself, sequential consistency is not a convergent protocol.
