    • PROBLEM TO BE SOLVED: To suppress the use of a route including a loop.SOLUTION: A first node device in a network including a plurality of node devices transmits a route information frame. The route information frame includes route information in which a destination node device to which a frame can be transmitted from the first node device is associated with a transmission destination to which the first node device transmits the frame destined to the destination node device. A second node device adjacent to the first node device receives the route information frame. The second node device decides whether a loop is included in a route from the second node device to the destination node device through the first node device and the transmission destination. The second node device stores the route information used to generate the route decided not to include a loop, to perform transmission processing using the stored route.
    • 要解决的问题:抑制包括循环的路由的使用。解决方案:包括多个节点设备的网络中的第一节点设备发送路由信息帧。 路线信息帧包括其中可以从第一节点设备发送帧的目的地节点设备与第一节点设备发送去往目的地节点设备的帧的传输目的地相关联的路由信息​​。 与第一节点设备相邻的第二节点设备接收路由信息帧。 第二节点设备通过第一节点设备和发送目的地决定在从第二节点设备到目的地节点设备的路由中是否包括循环。 第二节点设备存储用于生成决定为不包括循环的路由的路由信息​​,以使用存储的路由进行传输处理。

    • PROBLEM TO BE SOLVED: To enable accurate monitoring of a communication path state in a network.SOLUTION: A node device includes a selector unit, a transmitter unit, a decision unit and a generator unit. The selector unit selects a transmission destination of a survey frame for use for the survey of a route state from a data transmission source node device to a data transmission destination node device, from frame transfer destination node devices destined to the destination node device. The transmitter unit transmits a first survey frame to a first node device selected to be the transmission destination of the first survey frame. The decision unit decides whether the transmission of the first survey frame is successful. If the transmission of the first survey frame fails, the generator unit generates a second survey frame in which a communication failure with the first node device is recorded. The transmitter unit transmits the second survey frame to a second node device selected to be the transmission destination of the second survey frame.
    • 要解决的问题:为了能够准确地监视网络中的通信路径状态。解决方案:节点设备包括选择器单元,发送器单元,判定单元和发电机单元。 选择器单元从目的地到目的地节点设备的帧传送目的地节点设备中选择用于从数据发送源节点设备到数据发送目的地节点设备的路由状态的调查使用的调查帧的发送目的地。 发射机单元将第一测量帧发送到被选择为第一测量帧的发送目的地的第一节点设备。 决定单元决定第一测量帧的发送是否成功。 如果第一测量帧的传输失败,则发生器单元生成第二测量帧,其中记录与第一节点设备的通信故障。 发射机单元将第二测量帧发送到被选择为第二测量帧的发送目的地的第二节点设备。

    • PROBLEM TO BE SOLVED: To shorten time to access common data. SOLUTION: A management apparatus 100 stores common data, which are utilized commonly in a system, in a common data storage unit 110 while dividing the common data by classes and in a case where requests of access to the common data are accepted from a plurality of individual devices, an access content determination unit 140 correspondingly registers identification information of the accepted access requests and multicast group IDs in a multicast group ID buffer 120. A common data management unit 160 then multicast-transfers the common data of a relevant class to each of the plurality of individual devices that becomes a transmission source of the access request corresponding to the class of the common data.
