摘要： In a communication apparatus on a network having ring topology and connecting plural communication apparatuses such that adjacent communication apparatuses are connected through plural lines, a first detecting unit detects failure occurring in a line included in a relay path set between the communication apparatus and another communication apparatus on the network. When the first detecting unit detects failure, a switching unit switches the relay path to a relay path connecting the communication apparatuses on the network in a direction opposite to the relay path originally set. A second detecting unit detects failure occurring in a line included in the relay path switched to by the switching unit; and when the second detecting unit detects failure, a resetting unit resets the relay path using a line where no failure has been detected.

摘要： In a communication device for monitoring a network system where a frame is transferred, with a maintenance frame for maintenance and management, an input-output section inputs or outputs a frame. A failure detection section detects occurrence of a failure in the network system on the basis of the inputted frame. A setting section sets the communication device according to the detection of the failure so as to terminate or transfer a data frame inputted from the input-output section. A data frame control section controls whether to terminate or transfer the data frame, according to the setting of the data frame by the setting section. A maintenance frame control section controls whether to terminate or transfer the maintenance frame inputted from the input-output section, according to the setting of the data frame by the setting section.

摘要： The relay apparatus relays frames in which a plurality of network identifiers are set and comprises a frame determining unit, a converting unit, and a sending unit. The frame determining unit determines whether a frame received at a communication port is a specific frame or not. The converting unit converts, when it is determined that the received frame is a specific frame and when the communication port is a blocking port, a network identifier set in the specific frame to another network identifier among the plurality of network identifiers. The sending unit sends the specific frame, the network identifier of which has been converted by the conversion unit, from a port opposing the communication port.

摘要： The bridge device is connected to a layer-2 network. The Query message distribution unit discriminates, distributes, and outputs the normal Query messages and abnormal Query messages among the received Query messages. The abnormal message processing unit counts the number of received abnormal Query messages, and the normal message processing unit counts the number of normal Query messages. The router connection state judgment unit judges that the bridge device is a bridge device that is adjacent to the router when only the number of normal Query messages is counted and outputs an instruction to change the bridge ID to the STP processing unit. The STP processing unit establishes the bridge ID as a minimum value and renders the bridge device a root bridge.
