Standard real-time models do not consider the fact that a chosen technical deadline is different from the critical latency where the service utility becomes zero.  But this fact is rather important for engineering practice.
In this talk we present a tolerance-based refinement of the real-time model.  By doing so we make the process of deriving the estimation of the critical latency explicit.  The difference between the technical deadline and the critical latency is a measure for the safety margin of the system.  This safety margin is important for both, soft real-time and hard real-time systems, though with different quantities and qualities.  Furthermore, we explain why the critical latency can hardly be quantified by a concrete value.  However, we demonstrate how to derive reasonable estimates for it.  We use a concrete application to show how the distinctive knowledge of the critical latency and the technical deadline are useful for real-time scheduling.  As an outlook we argue by examples how this tolerance-based model is also applicable beyond just real-time performance, like optimised energy management.<\/p>\n\n\n\n

We are also inviting top experts in AI and Knowledge Technologies to discuss major socio-technological topics with an audience that comprises both members of the Knowledge Media Institute, as well as the wider staff at The Open University. Differently from our seminar series, these events follow a Q&A format.<\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
