On the Stability of Redundancy Models

The main motivation to investigate redundancy models comes from empirical evidence suggesting that can help improve the performance of real-world applications. Although there are several variants a redundancy-based system, general notion is create multiple copies same job will be sent subset servers. By allowing for redundant copies, aim minimize system latency by exploiting variability in queue lengths and capacity different In this article, stability condition multiserver systems investigated. Several popular scheduling disciplines considered, such as first-come-first-serve (FCFS), processor sharing (PS), random order service (ROS) show whereas with ROS not reduced, both PS FCFS severely degrade.
