摘要： A Provider Edge PE3 replicates a received packet and relays these to virtual circuits VC1, VC2 respectively, and Provider Edges PE2, PE2 respectively receive the packets from the virtual circuits VC1, VC2, whereupon the Provider Edges PE2, PE2, on the basis of an agreement between them, decide to handle the received packets such that one of the first edges relays the packet to a Customer Edge CE1 for forwarding to a Host A, while the other edge discards the packet without relaying it to the Customer Edge CE1.

摘要： A network relay system includes a plurality of internal network relay devices. The network relay system learns multiple pieces of route information to an external network, creates a plurality of allocation route tables designed to allocate the learnt multiple pieces of route information to the internal network relay devices. The network relay system then generates address space information showing a correlation of IP address ranges on an IP address space between the allocation route tables and respectively registers the allocation route tables, along with the generated address space information, in the internal network relay devices. Each of the internal network relay devices transfers a data frame, based on the address space information and the allocation route table registered in the self-device.

摘要： In a ring network including an old master node 100, a new master node 110 is used as a replacement for the old master node 110. During replacement operation, when detecting that two ring ports of the new master node 110 are set in link-up state, the new master node 110 gives a transit node 200 an instruction to forward a health check frame H102 sent from a ring port 102 of the old master node 100 by a forwarding route going through the new master node 110. The new master node 110 can monitor the status of the ring network by receiving the health check frame H102. This configuration enables continuous monitoring for a failure occurring in the ring network during replacement of the master node.
摘要翻译：在包括旧主节点100的环网中，使用新的主节点110作为旧主节点110的替代。在替换操作期间，当检测到新的主节点110的两个环形端口被设置为链路状态下，新的主节点110向转发节点200发送通过经过新的主节点110的转发路由转发从旧主节点100的环形端口102发送的健康检查帧H102的指令。新的主节点110 可以通过接收健康检查框H102来监控环网的状态。该配置可以在主节点更换期间对环网发生故障进行持续监控。
