Task Completion Timed reliability without restart, rejuvenation, or checkpointing. Task completion time is considered in general [15] in unreliable systems that are subject to failures. The three mechanisms can be evaluated by how much they improve the task completion time at what cost. To be able to value the benefit

Applicability Analysis of Restarthen a page takes too long to load in a web browser clicking the reload button in many cases helps. In [85] the technical background of this fact is discussed in detail, explaining how clicking the reload button ‘overrules’ the TCP retransmission timer, potentially improving the overall download time

Meeting Deadlines Through Restartn to let it continue. Whether restart is indeed faster depends on the completion time distribution of tasks, and on the correlation between the completion times of consecutive tries. As in the previous chapter also in this chapter we assume that the completion times of consecutive tries are independ

Practical Aspects of Preventive Maintenance and Software Rejuvenationntation the design of a new product is evaluated by means of formal and stochastic modelling. Later in the product development process prototypes are modelled, evaluated and improved. Therefore, stochastic modelling must follow or accompany the system development process. As stochastic modelling ope

Checkpointing Systemsorms transactions, or executes long-running batch processes. If the execution time of the task and the time at which processing starts is known, then the moment of completion of the task is known as well. If failures can happen the completion of a task severely depends on the underling fault model.
