Brunhilde was designed as a resilient bidirectional ring network for applications such as safety-critical public address (in Wagner's opera, when Brunhilde is engulfed by fire the ring survives). Some of the technology was inherited from CoRoNet, which was also a bidirectional ring and was in turn developed from Multilink and Superlink, which were unidirectional rings. As shown here, nodes had two network interfaces and were chained together to form a “segment”; the protocols (including synchronisation methods) on a segment were different from those on a link between switches. It has been superseded by Flexilink, in which the protocols used on links between switches are also suitable for use on a segment.
