Recovery processing for high availability stream processing systems in local area networks

In this paper, we investigate recovery processing for stream processing systems with high availability in local area networks (LANs) in which not so many resources are available. We focus on a simple high availability distributed stream processing system model where each processing node in a query network has a backup node. We discuss pros and cons of several approaches to recovery processing from single-node fail-stop failures in the system model running in LANs with limited resources. In particular, we compare the approaches in terms of suitability to LANs, recovery cost and throughput. Some results of simulation in which recovery approaches were compared in terms of recovery cost and throughput are shown.
