摘要： A repeater and method provides a technique to minimize congestion and packet loss, which may be generated when a fault is detected in a ring type packet network or when the network recovers from such a fault. A repeater having a plurality of ports for transmitting and receiving packets in a ring type network for transmitting the received packets on the basis of an address included in a received packet and a transmitting port database indicating an identifier of a port to transmit the packet having the address as the destination, comprises a control packet processing block to detect reception of a fault notifying packet transmitted from a repeater having detected a fault and a control block to update, upon reception of the fault notifying packet from an immediately adjacent repeater, a port identifier of the transmitting port database having a port identifier of the port having received said fault notifying packet into a port identifier of a port connected to another immediately adjacent repeater.

摘要： A data relay apparatus stores identification information for identifying itself. A blocking unit blocks a port to avoid an occurrence of a loop path if the data relay apparatus is a master node, and blocks a port connected to a link of the data relay apparatus if a failure occurs to the link. When the link is restored from the failure, a comparing unit compares identification information of other apparatus connected to the link, with the identification information stored. Based on a result of the comparison, a determining unit determines whether the data relay apparatus should be set as a master node.
摘要翻译：数据中继装置存储用于识别自身的识别信息。如果数据中继装置是主节点，则阻塞单元阻塞端口以避免出现循环路径，并且如果链路发生故障，则阻塞连接到数据中继装置的链路的端口。当链接从故障恢复时，比较单元将连接到链路的其他设备的识别信息与存储的识别信息进行比较。基于比较的结果，确定单元确定数据中继设备是否应当被设置为主节点。

摘要： A data relay apparatus includes a storage unit that stores information generated based on contents of data, a determining unit that determines, based on the information, whether a communication path relating to the data is in a loop state when the data is received, and a limiting unit that limits relay of the data when the determining unit determines that the communication path is in the loop state.
