Timed Runtime Monitoring for Multiparty Conversations

Neykova, Rumyana, Bocchi, Laura, Yoshida, Nobuko (2014) Timed Runtime Monitoring for Multiparty Conversations. In: Proceedings Third Workshop on Behavioural Types. Electronic Proceedings in Theoretical Computer Science . pp. 19-26. (doi:10.4204/EPTCS.162.3) (KAR id:43736)


We propose a dynamic verification framework for protocols in real-time distributed systems. The framework is based on Scribble, a tool-chain for design and verification of choreographies based on multiparty session types, developed with our industrial partners. Drawing from recent work on multiparty session types for real-time interactions, we extend Scribble with clocks, resets, and clock predicates constraining the times in which interactions should occur. We present a timed API for Python to program distributed implementations of Scribble specifications. A dynamic verification framework ensures the safe execution of applications written with our timed API: we have implemented dedicated runtime monitors that check that each interaction occurs at a correct timing with respect to the corresponding Scribble specification. The performance of our implementation and its practicability are analysed via benchmarking.
