摘要： The present invention discloses a method and an apparatus for recovering unicast traffic during an Ethernet ring failover, relates to the field of communication technologies, and solves the problem of interruption of the unicast traffic caused by a link failure during the Ethernet ring failover and before completion of flushing of the MAC address table. In embodiments of the present invention, because a network switch sets the broadcast flags of the ports in the loop of the Ethernet ring to the set state before completion of flushing of the MAC address table, if the broadcast flag of the destination port corresponding to the destination address in a unicast packet received by the network switch is in the set state, the network switch broadcasts the unicast packet. Therefore, the network switch in the loop of the Ethernet ring can recover the interrupted unicast traffic without waiting for completion of flushing of the MAC address table, thereby implementing recovering the unicast traffic during an Ethernet ring failover.

摘要： PROBLEM TO BE SOLVED: To reduce the problem of the disturbed sequence of a plurality of unicast packets successively transmitted in order, before the update of a MAC address table is completed in a ring failure avoidance system.SOLUTION: A network switch sets a broadcast flag of a port in the loop of an Ethernet ring to a set state before the completion of updating the MAC address table. When a broadcast flag of a destination port corresponding to the destination address of a unicast packet received by the network switch is in the set state, the network switch broadcasts the unicast packet. Accordingly, the network switch in the loop of the Ethernet ring can recover the interrupted unicast traffic without waiting for the completion of the MAC address table update. Thus, the unicast traffic can be recovered in the middle of the execution of the Ethernet ring failure avoidance system.
摘要翻译：要解决的问题：为了减少在环路故障回避系统中完成MAC地址表的更新之前依次顺序发送的多个单播分组的干扰序列的问题。解决方案：网络交换机在完成更新MAC地址表之前，将以太网环路环路中的端口的广播标志设置为设置状态。当与由网络交换机接收到的单播分组的目的地地址相对应的目的地端口的广播标志处于设置状态时，网络交换机广播单播分组。因此，以太网环路环路中的网络交换机可以恢复中断的单播流量，而无需等待MAC地址表更新的完成。因此，在以太网环路故障回避系统的执行过程中，可以恢复单播流量。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a system and a method which efficiently process accesses from nodes connected with a ring network using time division multiplexing.
SOLUTION: The system includes: a plurality of nodes 20 which receive only optical signals, the wavelength or position space of which is assigned to the nodes, and transmit optical signals, the wavelength or position space of which is assigned to other nodes, to the other nodes; and a ring network 30 which time division multiplexes a plurality of optical signals and transmits them. The ring network 30 forms slots to transmit various wavelength optical signals, and includes information which indicates whether or not each slot has optical signals to be transmitted. The node 20 includes: an update means 25 where information included in a slot corresponding to a node which receives optical signals is not checked and the information is updated to information which indicates the existence of optical signals; and a determination means 26 for operating in the same clock cycle as information update executed by the update means 25 and determining whether or not to transmit optical signals based on the information.

摘要： PROBLEM TO BE SOLVED: To improve band use efficiency and tolerance against multiple failures. SOLUTION: A network 100 is a ring-shaped network connecting communication apparatuses 110, 120, 130 and 140 via a plurality of lines to be handled as one transmission line. The communication apparatus 110 detects a fault on any one of the plurality of lines included in a relay path set with the other communication apparatus 130 on the network 100. When any fault is detected, the relay path is switched to a path in an opposite direction on the network 100. Furthermore, a fault in any one of a plurality of lines included in the switched relay path is detected. When any fault is detected, a relay path is reset using lines, where no fault is detected, among a plurality of lines. COPYRIGHT: (C)2010,JPO&INPIT
