Comunicação remota em uma arquitetura de suporte a simulação distribuída

Abstract

The Repository Manager of Distributed Co-Simulation Backbone (DCB) is a system developed in Java language that helps designers of simulation models to create their simulation environments. Although functional, the manager needs some improvements. One of them is to provide communication between different repositories located in a distributed system (in different machines), that is the motivation of this work. There are different solutions for provide communication in distributed system, as sockets, SOAP, CORBA and RMI. Performance comparisons for systems developed in Java using these different technologies shows that RMI (Remote Method Invocation) is a good solution. RMI consists of a programming interface that provides the execution of remote calls in applications developed in Java. In this work, the communication between the different repositories of Repository Manager was implemented using RMI and working in a client-server model. The implemented model allows designers to have access to different elements of simulation that are managed by other tutors, in a transparent manner, and without requiring specific knowledge of communication between computers.
