In order to verify that the use of these protocols, expressed in SDL, is transparent to the user, we explore the feasibility of their bisimulation checking. We discuss the main issues involved in translating SDL into Concurrency Workbench, a tool for performing bisimulation checking, and apply the results to verifying correctness of AR protocols.
