Random arrivals in fixed priority analysis

Fixed priority worst case response time analysis is well studied and is widely used in many real systems to guaran-tee deadline-based timing requirements in concurrent sys-tems. This paper addresses the use of a non-bounded in-terference function in analysis. An outline of a probabilis-tic analysis is presented which is based on a simple random arrival model. The analysis produces a probability distri-bution of response times. The analysis is derived from an analysis of random faults on CAN and inherits some limita-tions from this. 1
