Quiet and Bouncing Objects: Two Migration Abstractions in a Simple Distributed Blue Calculus

In this paper, we study a model of migrating objects based on the blue calculus, extended with a very simple system of localities. We show how two migration behaviors can be defined, namely those of bouncing and quiet objects. These migration control abstractions are defined separately from other aspects of the object definition and can be easily reused, thus providing more flexibility in the definition of migration constraints.
