The demand for real-time data storage in distributed control systems (DCSs) is growing. Yet, providing real-time DCS guarantees is challenging, especially when more and more sensor and actuator devices are connected to industrial plants and message loss needs to be taken into account.In this paper, we investigate how to build a shared memory abstraction for DCSs as a first step towards implementing...
To increase their dependability, distributed control systems (DCSs) need to agree in real time about which hosts have crashed, i.e., they need a real-time membership service. In this paper, we prove that such a service cannot be implemented deterministically if, besides host crashes, communication can also fail. We define implementable probabilistic variants of membership properties, which constitute...
