    • A network system includes a plurality of networks, a first internetwork apparatus having a plurality of first ports each connected to the plurality of networks, a second internetwork apparatus having a plurality of second ports each connected to the plurality of networks, and a data transmission path connected to the first and second internetwork apparatuses to transmit data mutually between the first and second internetwork apparatuses. In the normal state, each of the plurality of first ports is caused to be able to transmit and receive data to and from one of the plurality of networks and the plurality of second ports are caused not to be able to receive data from the plurality of networks and to be able to transmit data to the plurality of networks. Whether a failure occurs in any of one of the plurality of first ports and a route between one of the plurality of first ports and one of the plurality of networks connected thereto is detected and the one of the plurality of first ports is caused not to be able to transmit and receive data to and from the one of the plurality of networks in response to detection of occurrence of failure. One of the plurality of second ports connected to the one of the plurality of first ports through the one of said plurality of networks is caused to be able to transmit and receive data to and from the one of the plurality of networks in response to detection of occurrent of failure.
    • 网络系统包括多个网络,第一互联网络装置,具有各自连接到多个网络的多个第一端口;第二互联网络装置,具有各自连接到多个网络的多个第二端口,以及数据传输路径 连接到第一和第二互联网络装置,以在第一和第二互联网络装置之间相互发送数据。 在正常状态下,使多个第一端口中的每一个能够向多个网络之一发送数据,并且使多个第二端口不能从多个第一端口接收数据 并且能够将数据发送到多个网络。 检测到多个第一端口中的任何一个中的任一个中是否发生故障,并且检测到多个第一端口中的一个与连接到其的多个第一端口中的一个之间的路由,并且使多个第一端口中的一个不是 能够响应于检测到故障的发生而向多个网络中的一个网络发送数据和从多个网络中的一个网络接收数据。 通过所述多个网络之一连接到多个第一端口中的一个的多个第二端口中的一个使得能够响应于检测到多个网络中的一个而向多个网络中的一个网络发送数据 发生故障。
