ELECTRA: making distributed programs object-oriented
Silvano Maffeis · 1993
Building failure-resilient, distributed software is difficult. In this paper we describe abstractions which help the programmer in developing such software systems by means of object-oriented programming. An object-oriented toolkit called Electra is presented, which provides abstractions for Remote Method Calling (RMC), object-groups, object-group communication with type checking, object-location trading and so forth. Electra allows the building of failure-resilient, directly distributed systems by reusing software components. With a simple example we demonstrate how a distributed, faulttolerant client-server application can be realized in Electra. Keywords: Failure-Tolerance, Object-Groups, Object-Oriented Distributed Programming, Replication, Reusability 1 Introduction There are two important requirements which toolkits for the development of reliable distributed systems should fulfill: one is to provide powerful abstractions which help programmers in building reliable distributed ...
