PACKET RING NETWORK SYSTEM, METHOD OF CONNECTING PACKET RINGS, AND INTER-RING CONNECTING NODE

摘要

[Problems] To enable each of a plurality of links connecting rings to perform packet transfer while preventing multiple reception of packets and broadcast stream in a normal state where no failure has occurred.;[Means for Solving Problems] An inter-ring connecting node 101a and an inter-ring connecting node 102a are connected, and similarly, an inter-ring connecting node 101b and the inter-ring connecting node 102b are connected. When each of the inter-ring connecting nodes 102a and 102b receives a packet to be broadcasted via a link 103 or 104, it performs bidirectional flooding of the broadcast packet such that the packet arrives at a predetermined cleave point. At this time, each of the inter-ring connecting nodes 102a and 102b uses the source address of the other node so as to falsify the source.
