We report on an experiment in combining the theorem prover Isabelle with automatic first-order arithmetic provers to increase automation on the verification of distributed protocols. As a case study for the experiment we verify several averaging clock synchronization algorithms. We present a formalization of Schneider's generalized clock synchronization protocol [Sch87] in Isabelle/HOL. Then, we verify that the convergence functions used in two clock synchronization algorithms, namely, the...[Show more]
