Abstract: To meet the requirements of object migration and dynamic reconfiguration of networks and systems in large scale distributed systems, a hierarchical naming and addressing scheme is proposed, which uses location independent IDs and addresses representing objects’ location to identify objects. The scheme constructs global IDs and addresses from locally unique ones. They have relative representations, which are translated if they are transmitted among naming contexts. This ensures the uniqueness of IDs and shortens the size of IDs. The scheme also realizes the location transparency with respect to host migration and network reconfiguration. Implementation issues of this scheme are also disscussed.
