  • Control communications in communications networks
    Patent number: 7035209
    Abstract: A communications network has data and dedicated control network communication links between nodes. The control network is automatically and reliably created by each node determining each of its neighbor nodes to which it has a direct data link, each node having at least two neighbor nodes, and establishing a control network link for communicating control network traffic directly with each of these neighbor nodes. Each control network link can, if a dedicated control network link is not available, use bandwidth of a data link between the respective nodes, a link selection protocol being based on shared risk link groups and available bandwidth.
    Type: Grant
