  abstract = {<p> This paper presents a lightweight reliable object
 migration protocol that preserves the centralized
 object semantics, allows for precise prediction of
 network behavior, and permits construction of
 fault tolerance abstractions in the language.
 Each object has a ``home site'' to which all
 migration requests are directed.  Compared to the
 standard technique of creating and collapsing
 forwarding chains, this gives a better worst-case
 network behavior and it limits dependencies on
 third-party sites.  The protocol defines ``freely
 mobile'' objects that have the interesting
 property of always executing locally, i.e., each
 method executes in the thread that invokes it.
 This makes them dual, in a precise sense, to
 stationary objects.  The protocol is designed to
 be as efficient as a nonreliable protocol in the
 common case of no failure, and to provide
 sufficient hooks so that common fault tolerance
 algorithms can be programmed completely in the Oz
 language.  The protocol is fully implemented in
 the network layer of the Mozart platform for
 distributed application development, which
 implements Oz (see <a
 href="http://www.mozart-oz.org"><tt>http://www.mozart-oz.org</tt></a>).
 This paper defines the protocol in an intuitive
 yet precise way using the concept of
 <i>distribution graph</i> to model distributed
 execution of language entities.  Formalization and
 proof of protocol properties are done elsewhere.
