With very well-engineered hubs, the star-wiring configuration is more than just possible; it makes the system much more robust and reliable. Redundant Ring Data networks are critical for production, security, and information exchange, any system downtime is very costly – and even deadly in some situations.
With an extra self-healing redundant link, a system will not break down even if there is a breaking point in the system, as these redundant-ring networks work both clockwise and counter-clockwise. If the clockwise link is down, the counter-clockwise link will recover the system instantly.
