Formal modeling and analysis of a critical time communication protocol
Résumé
In this paper, a communication protocol based on a local area network (fieldbus for example) in which a producer periodically sends data to a consumer (the consumer wishes to consume within a time window) is considered. Data transmission is assumed to occur with jitter. Using a Petri net based model, this protocol is formally modelled and the quality of the service is qualitatively and quantitatively assessed.
