Titre anglais : Behavioural and Structural Composition Rules Preserving Liveness by Synchronization for Coloured FIFO Nets
Abstract : This paper deals with the compositionality of liveness when synchronizing two coloured FIFO nets. The composition operator allows to merge transitions as well as some adjacent places or queues.
A behavioural sufficient condition for liveness compositionality relies on a mutual non constraining relation between component nets.
A structural sufficient condition for synchronization preserving liveness is then given in the case of a state machine at the interface of the merged elements with the non merged ones of each component net. It requires that the conflictual coloured transitions of the interface state machines satisfy the structural freeing or blocking relations.
Finally an example shows how these conditions simplify the analysis of a protocol within a layered architecture.
Key-words : blocking relation, coloured FIFO nets, compositionality, equal conflict, freeing relation, liveness, non constraining relation, state machine, synchronization, synchronization medium
