Shishira.S.Vasan, Dr. Anirban Basu . Improving Network Availability by Software Rejuvenation. International Journal of Computer Applications. 29, 8 ( September 2011), 1-4. DOI=10.5120/3587-4969
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.
