Solutions to make Java-RMI time predictable

Java-RMI is a well-known distribution middleware framework that allows the invocation of remote methods. The paper describes the extension of Java-RMI model to make the remote method calls time predictable. We identify the problems of the jdk implementation of RMI and propose solutions to implement the Java-RMI extended model. This extended model and the proposed solutions are based on the Java and CORBA real-time extensions and especially on network resource reservation protocols. These extensions provide services for the network resource negotiation and to limit the latency of RMI services. The proposed solutions can be integrated in jdkl.2 RMI implementation, using the Java real time package and RSVP implementations
