This paper addresses the use of a non-bounded interference function caused by random arrivals in worst case response time analysis. An outline of a probabilistic analysis is presented which is based on a simple random arrival model. The analysis produces a probability distribution of response times. The analysis is derived from an analysis of random faults on CAN and inherits some limitations from this. We report this analysis as a stand-alone result and observe that for some systems this analysis can be directly applied. However, work is in progress to remove these limitations.
