Normal 802.3 Ethernet requires a tree topology. If a ring or a loop exists, then packets will be forwarded around the ring indefinitely. If the ring is broken, then there is no possibility of packets being propagated forever. This invention shows how to quickly impose a virtual break in the ring such that all nodes can communicate with each other, and how to remove the virtual break when a real failure occurs. This is accomplished by placing intelligent nodes on the ring that work together to virtually break and restore the ring. An embodiment is disclosed that handles a unidirectional break in a communication link.

L'Ethernet 802.3 normal nécessite une topologie en arbre. S'il existe un anneau ou une boucle, alors des paquets sont réacheminés autour de l'anneau indéfiniment. Si l'anneau est cassé, alors la propagation des paquets est impossible pour toujours. La présente invention concerne la manière selon laquelle imposer rapidement une rupture virtuelle dans l'anneau de sorte que l'ensemble des noeuds puisse communiquer les uns avec les autres, ainsi que la façon selon laquelle éliminer la rupture virtuelle lorsqu'une défaillance réelle se produit. Pour ce faire, des noeuds intelligents sont placés sur l'anneau, lesquels fonctionnent ensemble pour rompre et restaurer virtuellement l'anneau. Dans un mode de réalisation, l'invention concerne la gestion d'une rupture unidirectionnelle dans une liaison de communication.
