Abstract
Location-independent references include a live reference containing a location of a remote object and a universally unique identifier (UUID) which provides a unique global reference to that remote object. If a method call to the remote object using the live reference fails, the UUID is used to obtain a new reference to the remote object and the new reference is then used to make another method call. A new reference can be obtained from an identifier directory that contains a mapping between UUIDs and location-independent references. When a remote object is first created, or when a remote object is moved from one location to another, the remote object registers with any and all such directories that it can find in its environment. These registrations are leased; that is, if they are not occasionally refreshed by the remote object which registered them, they are dropped from the directory.
