Abstract

In this paper, we design a real-time Java Remote Method Invocation (RMI). Real-time timing constraints are pre served in a server centric fashion where Java RMI servers keep information for real-time guarantees. Remote method invocations are modeled as sporadic events and so treated by a Total Bandwidth server, a guaranteed-rate scheduler. The replenishment period of the Total Bandwidth server is determined probabilistically. According to our measure ments, the overhead we added for implementing real-time capabilities is negligible and the latency of real-time RMI is very stable and predictable.
