Software systems often experience aging related defects which cause unexpected outages and disruption in traffic flow in a computer network affecting its availability. Complete collapse of a system due to aging related defects can be prevented by Software Rejuvenation. However, the process of rejuvenation consumes system resources during rejuvenation time, and affects the transmission of data through the node to different parts of the network during this time.In this paper, we discuss how communication disruption can be avoided and network availability improved when a node suffers from resource exhaustion. Simulation of the network proves the effectiveness of the method proposed in this paper in minimizing traffic disruption through a network. The paper also compares network availability for different software rejuvenation policies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
