Abstract

Lossy channel systems (LCS's) are systems of finite state automata that communicate via unreliable unbounded fifo channels. We propose a new probabilistic model for these systems, where losses of messages are seen as faults occurring with some given probability, and where the internal behavior of the system remains nondeterministic, giving rise to a reactive Markov chains semantics. We then investigate the verification of linear-time properties on this new model.
