A model of location transparency

Abstract

Location transparency removes the need for client objects to explicitly know or define the location of a server object when communicating. If a server object is capable of migration, relocation transparency maintains reference validity throughout the migration. Several models for providing location transparency exist, including the home location, forwarding locations and Stub-Scion Pair chain models. This paper proposes a model that uses a distributed registry system and dynamic reference updating to provide location and relocation transparency. A comparison of the models is presented.
