Remote procedure call protocols for real-time systems

Like all real-time services, the correctness of a real-time remote procedure call depends on the processing time of the calling algorithm, the traffic on the network and eventual failures of the communication network. If the deadline of an RPC cannot be met due to these problems, the result produced by the server will be of little or no use. The authors investigate three different protocols for real-time remote procedure calls and compare their performances. The protocols are designed for, respectively, hard-deadline requests with early guarantees, without guarantees, and soft deadline requests. They compare the performances of the three protocols by simulations.<
