Comparison of the FCFS and PS discipline in Redundancy Systems

Performance 2021-04-16 v1 Probability

Abstract

We consider the c.o.c. redundancy system with NN parallel servers where incoming jobs are immediately replicated to dd servers chosen uniformly at random (without replacement). A job finishes service as soon as the first replica is completed, after which all the remaining replicas are abandoned. We compare the performance of the first-come first-served (FCFS) and processor-sharing (PS) discipline based on the stability condition, the tail behavior of the latency and the expected latency.
