    • The network relay device of the invention carries out data transmission to and from an opposite device to relay data in a network. The network relay device includes: multiple ports connecting with corresponding multiple ports of the opposite device via multiple links; and a link aggregation control module that aggregates the multiple links to establish a link aggregation, which is regarded as one logic link, and carries out transmission of a control frame signal including a synchronization bit, as well as data transmission, at each port via the link aggregation. In response to detection of occurrence of a trouble in at least one of the aggregated multiple links, the link aggregation control module causes a port that connects with a normal link without the trouble among the multiple ports to stop the data transmission and send the control frame signal including the synchronization bit set equal to a first value. Here the first value functions to stop the data transmission at a corresponding port of the opposite device connecting with the normal link.
    • 本发明的网络中继装置对来自对方装置的数据进行数据传输,以中继网络中的数据。 网络中继设备包括:多个端口通过多个链路与相对设备的相应多个端口连接; 以及链路聚合控制模块,其聚合所述多个链路以建立被认为是一个逻辑链路的链路聚合,并且经由所述多个链路在每个端口上执行包括同步位的控制帧信号以及数据传输的传输 链接聚合。 响应于在至少一个聚合多个链路中发现故障的响应,链路聚合控制模块使得在多个端口中没有故障的与正常链路连接的端口停止数据传输并发送控制帧 包括等于第一值的同步位的信号。 这里,第一个值用于停止在与正常链路连接的相对设备的相应端口处的数据传输。
