Cyber-physical control applications impose strict requirements on the\nreliability and latency of the underlying communication system. Hence, they\nhave been mostly implemented using wired channels where the communication\nservice is highly predictable. Nevertheless, fulfilling such stringent demands\nis envisioned with the fifth generation of mobile networks (5G). The\nrequirements of such applications are often defined on the application layer.\nHowever, cyber-physical control applications can usually tolerate sparse packet\nloss, and therefore it is not at all obvious what configurations and settings\nthese application level requirements impose on the underlying wireless network.\nIn this paper, we apply the fundamental metrics from reliability literature to\nwireless communications and derive a mapping function between application level\nrequirements and network level parameters for those metrics under deterministic\narrivals. Our mapping function enables network designers to realize the\nend-to-end performance (as the target application observes it). It provides\ninsights to the network controller to either enable more reliability\nenhancement features (e.g., repetition), if the metrics are below requirements,\nor to enable features increasing network utilization, otherwise. We evaluate\nour theoretical results by realistic and detailed simulations of a factory\nautomation scenario. Our simulation results confirm the viability of the\ntheoretical framework under various burst error tolerance and load conditions.\n
