On Termination for Faulty Channel Machines

Patricia Bouyer, Nicolas Markey, JoëL Ouaknine, Philippe Schnoebelen & James Worrell
A channel machine consists of a finite controller together with several fifo channels; the controller can read messages from the head of a channel and write messages to the tail of a channel. In this paper, we focus on channel machines with insertion errors, i.e., machines in whose channels messages can spontaneously appear. Such devices have been previously introduced in the study of Metric Temporal Logic. We consider the termination problem: are all the computations...
