Publication Fault Tolerance and the Five-Second Rule(2015-05-01) Chen, Ang; Xiao, Hanjun; Haeberlen, Andreas; Phan, Linh T.X.We propose a new approach to fault tolerance that we call bounded-time recovery (BTR). BTR is intended for systems that need strong timeliness guarantees during normal operation but can tolerate short outages in an emergency, e.g., when they are under attack. We argue that BTR could be a good fit for many cyber-physical systems. We also sketch a technical approach to providing BTR, and we discuss some challenges that still remain.
