This paper presents two Compare&Swap protocols that, with respect to omission failures, are (1) fault-tolerant and (2) gracefully degrading, respectively. shows that fault-tolerance and gracefull degradation are close but distinct concepts, and that graceful degradation is inherently more costly than fault-tolerance. These Compare&Swap protocols are derived from consensus protocols proposed by Chandra, Jayanti and Toueg.
Index Terms:
Compare&Swap, Crash Failure, Fault-Tolerance, Graceful Degradation, Omission Failure, Wait-free Synchronization.
