Testing for coordination fidelity

Abstract

Operation control in modern distributed systems must rely on decentralised coordination among system participants. In particular when the operation control involves critical infrastructures such as power grids, it is vital to ensure correctness properties of such coordination mechanisms. In this paper, we present a verification technique that addresses coordination protocols for power grid operation control. Given a global protocol specification, we show how we can rely on testing semantics for the purpose of ensuring protocol fidelity, i.e., to certify that the interaction among the grid nodes follows the protocol specification.
