  • Patent number: 6785226
    Abstract: The present invention relates in general to communication networks. In particular, the invention relates to a communication network in which nodes communicate via radio connections employing Ethernet protocol in a ring configuration which provides for fault tolerance and prevention of infinite communication loops. In a preferred embodiment, the network is in a ring configuration and comprises two routers for enabling fault tolerance in the event of a malfunctioning communication link and for preventing infinite message forwarding around the ring network. VLANS may be beneficially employed to assist with rerouting of data communication traffic in the event of a communication link failure and to aid in isolating customer network data from unauthorized viewing.
