This paper presents two software fault-tolerant real-time scheduling algorithms that are similar to EDF (earliest deadline first), called PKSA (probing K-step algorithm) and CUBA (changing utilization-based algorithm).

• 提出了两种类似EDF(earliest deadline first)的软件容错的动态实时调度算法:PKSA(probing K-step algorithm)和CUBA(changing utilization-based algorithm).
