Enforcing Availability in Failure-Aware Communicating Systems

Abstract : Choreographic programming is a programming-language design approach that drives error-safe protocol development in distributed systems. Motivated by challenging scenarios in Cyber-Physical Systems (CPS), we study how choreographic programming can cater for dynamic infrastructures where the availability of components may change at runtime. We introduce the Global Quality Calculus ($$GC_q$$), a process calculus featuring novel operators for multiparty, partial and collective communications; we provide a type discipline that controls how partial communications refer only to available components; and we show that well-typed choreographies enjoy progress.
