Ensuring deadlines of hard real-time applications in server-based deployments is a challenging problem, particularly if the workload arrives following an arbitrary arrival curve. This work extends the “(M, /K)-firm weakly hard” model to server-based systems, ensuring timely processing of real-time requests to the server. We introduce an admission policy to regulate the remote server workload and prevent deadline misses while attempting to admit more requests than the minimum required, when possible. We guarantee the weakly hard constraints through optimal resource allocation and server confiauration.
