[PROBLEMS] To enable each of links connecting rings to perform packet transmission while preventing multiple packet reception and generation of broadcast storm in a normal state when no failure has occurred. [MEANS FOR SOLVING PROBLEMS] An inter-ring connection node (101a) is connected to an inter-ring connection node (102a). Similarly, an inter-ring connection node (101b) is connected to an inter-ring connection node (102b). When the inter- ring connection nodes (102a, 102b) receive a packet to be broadcasted via links (103, 104), respectively, they perform bidirectional flooding of the broadcast packet so as to reach a predetermined cleave point. Here, the inter- ring connection nodes (102a, 102b) use the other transmission source addresses between themselves so as to indicate false transmission sources.
La présente invention permet à chacun des anneaux de connexion de liaisons de transmettre des paquets tout en empêchant la réception multiple de paquets et l~apparition d~une tempête de diffusion dans un état normal, lorsqu~aucune erreur ne s~est produite. Le nAEud de connexion inter-anneaux (101a) est connecté à un nAEud de connexion inter-anneaux (102a). De façon similaire, le nAEud de connexion inter-anneaux (101b) est connecté au nAEud de connexion inter-anneaux (102b). Lorsque les nAEuds de connexion inter-anneaux (102a, 102b) reçoivent un paquet à diffuser via les liaisons (103, 104), respectivement, ils envoient de façon bidirectionnelle le paquet à diffuser de façon à atteindre un point de diffusion prédéterminé. Ici, les nAEuds de connexion inter-anneaux (102a, 102b) utilisent les autres adresses de sources de transmission entre eux de façon à indiquer les mauvaises sources de transmission.
