💍 Unidirectional vs Bidirectional
In a standard Ring, data travels in one direction (Unidirectional). If a wire breaks, the network dies.
In a Dual Ring (or Bidirectional Ring), there is a backup path. If the primary path fails, data reverses direction to reach the destination.

Click a wire to cut the ring.
Watch the system switch from Unidirectional (Clockwise) to Bidirectional (Counter-Clockwise) routing.
➡️ Unidirectional
Normal Operation. Token passes 1->2->3->4. Simple and collision-free.
🔄 Bidirectional / Dual
Emergency Operation. If 2->3 is cut, PC1 sends data 1->6->5->4->3. This requires a Dual Ring architecture (like FDDI).
