....by which they may be identified and looked up in location tables, but which convey no locationdependent component. Clients wishing to contact an object pass its name to a location service which finds the object s current address and returns it. Pure Naming This approach is used by the Globe [23] Object Model to allow objects to be migrated and replicated transparently. Globe uses a distributed search tree to locate objects. The search tree s layout should ideally match the topology of the underlying network. Because the names of Globe objects are pure, they do not contain information ....

....gateway to the new location, and returns forwarding exceptions to clients access the device s objects. Frequently moving objects pose a problem for ALICE, since CORBA object references have limitless lifetimes and so forwarding references cannot be safely collected. The Globe Location Service[15], developed to support the Globe object model, is built around a tree structured network of node points with which objects register as they migrate. When locating objects, clients supply a at, globally unique name to the location service. This avoiding the performance bottleneck of communicating ....

....24a Trumpington Street, Cambridge, England 2 Existing Mobile Location Schemes Pure vs Impure Names The issue of transparent location is tackled by a number of different schemes, which can be divided, for the most part, into three general categories; 1. Schemes such as the Globe Object Model s[7] location service, that use pure names[11] which convey no information to the client as to how the corresponding entity should be located. These systems are seldom as scalable as we might like, since most implementations require that some central node is aware of every object in existence. 2. ....
