Adapter rings technology is a local area . It uses a special three-byte frame called a token that travels around the adapter rings.  Adapter ring frames travel completely around the loop.Stations on a  adapter ring  are logically organized in a adapter ring topology with data being transmitted sequentially from one adapter ring station to the next with a control  circulating around the adapter ring controlling access.
