摘要： An inspection signal to inspect forward-path or return-path communication, is transmitted from a reference node of a network. A response signal is transmitted in a priority class from a node of a forward path to the reference node. In the case of inspection of return-path communication, a replica of the response signal is transmitted in a non-priority class from the node of the forward path to the return path, and the node that receives the replica of the response signal transfers the replica in a priority class to the reference node. In the case of inspection of forward-path communication, a replica of the inspection signal is transmitted in a non-priority class from the node of the forward path to the forward path, and a replica of the response signal is transmitted in a priority class from the node that receives a replica of the inspection signal to the reference node.

摘要： The clock synchronization accuracy between a master node and a slave node is stably measured. The slave node synchronizes its own clock with the clock of the master node by means of the packets transmitted from the master node. It reproduces the clock of the slave node by means of the transmitted packets, accumulates information on the transmitted packets and the clock of the slave node and performs clock synchronization on the basis of the accumulated information.

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.
