Abstract

An efficient distributed object-oriented computation model based on the process-object model is presented. The model uses remote processes, instead of remote objects, to handle the communications among nodes, where explicit message passings among processes are used to reduce the communication overhead (times) in remote-object models. A remote process object can be forked easily and efficiently to execute a sequence of statements specified locally, and distributed garbage collection is not necessary. The system can be further enhanced in the following areas: (1) concurrency control, (2) protection mechanism, (3) high layer distributed system services, and (4) real-time system support
