Handling heterogeneity in computer systems without decreasing user productivity and without increasing development costs demands special software structures. This paper presents a flexible software structure that has been used to construct heterogeneous remote procedure call, naming, electronic mail, filing and remote computation services. This structure captures the heterogeneous aspects of a service in a set of abstract interfaces. Clients of the service are built in terms of the abstract interfaces, but one of multiple implementations of those interfaces, called proxies , is dynamically selected to satisfy the demands of heterogeneity.
