Abstract
A multiple counter-rotating ring computer network system having a permission control scheme for client isolation. The peripheral channel allows two rings to be folded into one longer ring so that faulty nodes can be effectively removed from the network. Or, any of the rings can be masked so that they are unoperational. The network system also allows several client isolation states ranging from complete isolation to master access. These types of isolation allow faulty client devices to be tested while maintaining a high-level of network security by configuring the client to an appropriate isolation state.
