Roll your own test bed for embedded real-time protocols: a haskell experience

We present by example a new application domain for functional languages: emulators for embedded real-time protocols. As a case-study, we implement a simple emulator for the Biphase Mark Protocol, a physical-layer network protocol in Haskell. The surprising result is that a pure functional language with no built-in notion of time is extremely well-suited for constructing such emulators. Furthermore, we use Haskell's property-checker QuickCheck to automatically generate real-time parameters for simulation. We also describe a novel use of QuickCheck as a "probability calculator" for reliability analysis.
