Communications network for use in critical control systems has hubs, with each pair of hubs connected by bidirectional link having failure handling measures

摘要

The network includes at least two nodes connected through at least a first hub. A second hub is provided identical to the first hub. Each pair of hubs is interconnected by a bidirectional link having failure handling measures. Each hub connects the contributions of the connected nodes with the contributions received by the other hubs. An independent claim is included for a network connection method.
