A cache consistency scheme is presented for a class of multiprocessors based on a hierarchy of rings. By taking advantage of the natural broadcast and ordering properties of rings, cache consistency is achieved via a simple, selective-broadcast based protocol requiring no complex hardware. Using address-trace driven simulations of the Hector shared-memory multiprocessor, it is shown that the scheme performs well
