摘要： A first node apparatus includes: ports; a storage device; and receiving, updating, and transmitting circuits. The storage device stores: information associating, with first identification information identifying a first frame, information distinguishing a first port having been used as a destination port when the first node apparatus has transmitted the first frame; and information associating, with each node apparatus, state information indicating whether frame transmission from each port is feasible. The receiving circuit receives, from a second node apparatus, a second frame including second identification information. When the second identification information is identical with the first, the updating circuit updates the state information associated with a node apparatus being a destination of the second frame to make the state information indicate frame transmission from the first port is not feasible. The transmitting circuit selects a second port from which transmission of the second frame is feasible, and transmits the second frame.

摘要： When stored identifying information of a transmission target frame and identifying information of a received frame are equal, a node apparatus updates transmission feasibility information stored in association with the final destination of the received frame. The transmission feasibility information indicates feasibility of transmission to each of a plurality of adjacent node apparatuses being a transmission destination, and is updated so that feasibility of transmission to the transmission destination associated with the identifying information of the received frame indicates that “the transmission is infeasible”. The node apparatus transmits the received frame, when there is no adjacent apparatus to which transmission is feasible, and when the stored identifying information of the transmission target frame is equal to the identifying information of the received frame, to the adjacent node apparatus recognized as the origin in association with the identifying information of the received frame.

摘要： In a node device 1 in a communication network, an FID management table 5 stores an FID for unique identification of a frame and the information about a destination node of the frame, and a weighting table 7 stores weighting information about another node as a destination for relay of the frame for each final destination node of the frame. When a frame transmitted to a local node is received, and if the FID of the received frame is stored in the FID management table 5, the data about the destination node associated with the FID is updated. If the FID of the frame received from the frame reception device is not stored in the FID management table 5, the FID management table 5 corresponding to the destination node of the frame is referred to, and another node as a destination for relay of the frame is determined.

摘要： A node apparatus changes a first access key unique to itself; changes a shared key same for node apparatuses; encrypts, using the shared key, the first access key and transmits it; receives an access key notification frame; decrypts it using the shared key, thereby obtaining a second access key; attaches, to a first plaintext frame, first signature data obtained by encrypting, using the shared key, data including a first value calculated from the first plaintext frame; encrypts the first plaintext frame using the second access key and transmits thus encrypted frame; receives a second encrypted frame; decrypts it by the first access key to obtain a second plaintext frame; obtains a second value by decrypting, using the shared key, a second signature data attached to the second plaintext frame; calculates a third value from the second plaintext frame; and confirms whether the second and third values are consistent.
